Merge tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management and ACPI updates from Rafael Wysocki:
"This includes fixes on top of the previous batch of PM+ACPI updates
and some new material as well.
From the new material perspective the most significant are the driver
core changes that should allow USB devices to stay suspended over
system suspend/resume cycles if they have been runtime-suspended
already beforehand. Apart from that, ACPICA is updated to upstream
revision 20160108 (cosmetic mostly, but including one fixup on top of
the previous ACPICA update) and there are some devfreq updates the
didn't make it before (due to timing).
A few recent regressions are fixed, most importantly in the cpuidle
menu governor and in the ACPI backlight driver and some x86 platform
drivers depending on it.
Some more bugs are fixed and cleanups are made on top of that.
Specifics:
- Modify the driver core and the USB subsystem to allow USB devices
to stay suspended over system suspend/resume cycles if they have
been runtime-suspended already beforehand and fix some bugs on top
of these changes (Tomeu Vizoso, Rafael Wysocki).
- Update ACPICA to upstream revision 20160108, including updates of
the ACPICA's copyright notices, a code fixup resulting from a
regression fix that was necessary in the upstream code only (the
regression fixed by it has never been present in Linux) and a
compiler warning fix (Bob Moore, Lv Zheng).
- Fix a recent regression in the cpuidle menu governor that broke it
on practically all architectures other than x86 and make a couple
of optimizations on top of that fix (Rafael Wysocki).
- Clean up the selection of cpuidle governors depending on whether or
not the kernel is configured for tickless systems (Jean Delvare).
- Revert a recent commit that introduced a regression in the ACPI
backlight driver, address the problem it attempted to fix in a
different way and revert one more cosmetic change depending on the
problematic commit (Hans de Goede).
- Add two more ACPI backlight quirks (Hans de Goede).
- Fix a few minor problems in the core devfreq code, clean it up a
bit and update the MAINTAINERS information related to it (Chanwoo
Choi, MyungJoo Ham).
- Improve an error message in the ACPI fan driver (Andy Lutomirski).
- Fix a recent build regression in the cpupower tool (Shreyas
Prabhu)"

- Schedule a page flip to the given frame buffer for the CRTC. This
- operation is called with the mode config mutex held.
- </para>
- <para>
- Page flipping is a synchronization mechanism that replaces the frame
- buffer being scanned out by the CRTC with a new frame buffer during
- vertical blanking, avoiding tearing. When an application requests a page
- flip the DRM core verifies that the new frame buffer is large enough to
- be scanned out by the CRTC in the currently configured mode and then
- calls the CRTC <methodname>page_flip</methodname> operation with a
- pointer to the new frame buffer.
- </para>
- <para>
- The <methodname>page_flip</methodname> operation schedules a page flip.
- Once any pending rendering targeting the new frame buffer has
- completed, the CRTC will be reprogrammed to display that frame buffer
- after the next vertical refresh. The operation must return immediately
- without waiting for rendering or page flip to complete and must block
- any new rendering to the frame buffer until the page flip completes.
- </para>
- <para>
- If a page flip can be successfully scheduled the driver must set the
- <code>drm_crtc->fb</code> field to the new framebuffer pointed to
- by <code>fb</code>. This is important so that the reference counting
- on framebuffers stays balanced.

-Samsung Exynos SYSRAM for SMP bringup:
-------------------------------------
-
-Samsung SMP-capable Exynos SoCs use part of the SYSRAM for the bringup
-of the secondary cores. Once the core gets powered up it executes the
-code that is residing at some specific location of the SYSRAM.
-
-Therefore reserved section sub-nodes have to be added to the mmio-sram
-declaration. These nodes are of two types depending upon secure or
-non-secure execution environment.
-
-Required sub-node properties:
-- compatible : depending upon boot mode, should be
- "samsung,exynos4210-sysram" : for Secure SYSRAM
- "samsung,exynos4210-sysram-ns" : for Non-secure SYSRAM
-
-The rest of the properties should follow the generic mmio-sram discription
-found in ../../misc/sysram.txt
-
-Example:
-
- sysram@02020000 {

- reg = <0x02020000 0x54000>;
- #address-cells = <1>;

+* ARM Secure world bindings
+
+ARM CPUs with TrustZone support have two distinct address spaces,
+"Normal" and "Secure". Most devicetree consumers (including the Linux
+kernel) are not TrustZone aware and run entirely in either the Normal
+world or the Secure world. However some devicetree consumers are
+TrustZone aware and need to be able to determine whether devices are
+visible only in the Secure address space, only in the Normal address
+space, or visible in both. (One example of that situation would be a
+virtual machine which boots Secure firmware and wants to tell the
+firmware about the layout of the machine via devicetree.)
+
+The general principle of the naming scheme for Secure world bindings
+is that any property that needs a different value in the Secure world
+can be supported by prefixing the property name with "secure-". So for
+instance "secure-foo" would override "foo". For property names with
+a vendor prefix, the Secure variant of "vendor,foo" would be
+"vendor,secure-foo". If there is no "secure-" property then the Secure
+world value is the same as specified for the Normal world by the
+non-prefixed property. However, only the properties listed below may
+validly have "secure-" versions; this list will be enlarged on a
+case-by-case basis.
+
+Defining the bindings in this way means that a device tree which has
+been annotated to indicate the presence of Secure-only devices can
+still be processed unmodified by existing Non-secure software (and in
+particular by the kernel).
+
+Note that it is still valid for bindings intended for purely Secure
+world consumers (like kernels that run entirely in Secure) to simply
+describe the view of Secure world using the standard bindings. These
+secure- bindings only need to be used where both the Secure and Normal
+world views need to be described in a single device tree.
+
+Valid Secure world properties:
+
+- secure-status : specifies whether the device is present and usable
+ in the secure world. The combination of this with "status" allows
+ the various possible combinations of device visibility to be
+ specified. If "secure-status" is not specified it defaults to the
+ same value as "status"; if "status" is not specified either then
+ both default to "okay". This means the following combinations are
+ possible:
+
+ /* Neither specified: default to visible in both S and NS */
+ secure-status = "okay"; /* visible in both */
+ status = "okay"; /* visible in both */
+ status = "okay"; secure-status = "okay"; /* visible in both */
+ secure-status = "disabled"; /* NS-only */
+ status = "okay"; secure-status = "disabled"; /* NS-only */
+ status = "disabled"; secure-status = "okay"; /* S-only */
+ status = "disabled"; /* disabled in both */
+ status = "disabled"; secure-status = "disabled"; /* disabled in both */

+UniPhier System Bus
+
+The UniPhier System Bus is an external bus that connects on-board devices to
+the UniPhier SoC. It is a simple (semi-)parallel bus with address, data, and
+some control signals. It supports up to 8 banks (chip selects).
+
+Before any access to the bus, the bus controller must be configured; the bus
+controller registers provide the control for the translation from the offset
+within each bank to the CPU-viewed address. The needed setup includes the base
+address, the size of each bank. Optionally, some timing parameters can be
+optimized for faster bus access.
+
+Required properties:
+- compatible: should be "socionext,uniphier-system-bus".
+- reg: offset and length of the register set for the bus controller device.
+- #address-cells: should be 2. The first cell is the bank number (chip select).
+ The second cell is the address offset within the bank.
+- #size-cells: should be 1.
+- ranges: should provide a proper address translation from the System Bus to
+ the parent bus.
+
+Note:
+The address region(s) that can be assigned for the System Bus is implementation
+defined. Some SoCs can use 0x00000000-0x0fffffff and 0x40000000-0x4fffffff,
+while other SoCs can only use 0x40000000-0x4fffffff. There might be additional
+limitations depending on SoCs and the boot mode. The address translation is
+arbitrary as long as the banks are assigned in the supported address space with
+the required alignment and they do not overlap one another.
+For example, it is possible to map:
+ bank 0 to 0x42000000-0x43ffffff, bank 5 to 0x46000000-0x46ffffff
+It is also possible to map:
+ bank 0 to 0x48000000-0x49ffffff, bank 5 to 0x44000000-0x44ffffff
+There is no reason to stick to a particular translation mapping, but the
+"ranges" property should provide a "reasonable" default that is known to work.
+The software should initialize the bus controller according to it.
+
+Example:
+
+ system-bus {
+ compatible = "socionext,uniphier-system-bus";
+ reg = <0x58c00000 0x400>;
+ #address-cells = <2>;
+ #size-cells = <1>;
+ ranges = <1 0x00000000 0x42000000 0x02000000
+ 5 0x00000000 0x46000000 0x01000000>;
+
+ ethernet@1,01f00000 {
+ compatible = "smsc,lan9115";
+ reg = <1 0x01f00000 0x1000>;
+ interrupts = <0 48 4>
+ phy-mode = "mii";
+ };
+
+ uart@5,00200000 {
+ compatible = "ns16550a";
+ reg = <5 0x00200000 0x20>;
+ interrupts = <0 49 4>
+ clock-frequency = <12288000>;
+ };
+ };
+
+In this example,
+ - the Ethernet device is connected at the offset 0x01f00000 of CS1 and
+ mapped to 0x43f00000 of the parent bus.
+ - the UART device is connected at the offset 0x00200000 of CS5 and
+ mapped to 0x46200000 of the parent bus.

+ARM System Controller ICST clocks
+
+The ICS525 and ICS307 oscillators are produced by Integrated Devices
+Technology (IDT). ARM integrated these oscillators deeply into their
+reference designs by adding special control registers that manage such
+oscillators to their system controllers.
+
+The ARM system controller contains logic to serialize and initialize
+an ICST clock request after a write to the 32 bit register at an offset
+into the system controller. Furthermore, to even be able to alter one of
+these frequencies, the system controller must first be unlocked by
+writing a special token to another offset in the system controller.
+
+The ICST oscillator must be provided inside a system controller node.
+
+Required properties:
+- lock-offset: the offset address into the system controller where the
+ unlocking register is located
+- vco-offset: the offset address into the system controller where the
+ ICST control register is located (even 32 bit address)
+- compatible: must be one of "arm,syscon-icst525" or "arm,syscon-icst307"
+- #clock-cells: must be <0>
+- clocks: parent clock, since the ICST needs a parent clock to derive its
+ frequency from, this attribute is compulsory.
+
+Example:
+
+syscon: syscon@10000000 {
+ compatible = "syscon";
+ reg = <0x10000000 0x1000>;

+Binding for Samsung S2M and S5M family clock generator block
+============================================================
+
+This is a part of device tree bindings for S2M and S5M family multi-function
+devices.
+More information can be found in bindings/mfd/sec-core.txt file.
+
+The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz
+outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs.
+
+To register these as clocks with common clock framework instantiate under
+main device node a sub-node named "clocks".
+
+It uses the common clock binding documented in:
+ - Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+
+Required properties of the "clocks" sub-node:
+ - #clock-cells: should be 1.
+ - compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk",
+ "samsung,s2mps14-clk", "samsung,s5m8767-clk"
+ The S2MPS15 uses the same compatible as S2MPS13, as both provides similar
+ clocks.
+
+
+Each clock is assigned an identifier and client nodes use this identifier
+to specify the clock which they consume.
+ Clock ID Devices
+ ----------------------------------------------------------
+ 32KhzAP 0 S2MPS11/13/14/15, S5M8767

+ 32KhzBT 2 S2MPS11/13/14/15, S5M8767
+
+Include dt-bindings/clock/samsung,s2mps11.h file to use preprocessor defines

+* STMicroelectronics STM32 DMA controller
+
+The STM32 DMA is a general-purpose direct memory access controller capable of
+supporting 8 independent DMA channels. Each channel can have up to 8 requests.
+
+Required properties:
+- compatible: Should be "st,stm32-dma"
+- reg: Should contain DMA registers location and length. This should include
+ all of the per-channel registers.
+- interrupts: Should contain all of the per-channel DMA interrupts in
+ ascending order with respect to the DMA channel index.
+- clocks: Should contain the input clock of the DMA instance.
+- #dma-cells : Must be <4>. See DMA client paragraph for more details.
+
+Optional properties:
+- resets: Reference to a reset controller asserting the DMA controller
+- st,mem2mem: boolean; if defined, it indicates that the controller supports
+ memory-to-memory transfer
+
+Example:
+
+ dma2: dma-controller@40026400 {
+ compatible = "st,stm32-dma";
+ reg = <0x40026400 0x400>;
+ interrupts = <56>,
+ <57>,
+ <58>,
+ <59>,

+ <68>,
+ <69>,
+ <70>;
+ clocks = <&clk_hclk>;
+ #dma-cells = <4>;
+ st,mem2mem;
+ resets = <&rcc 150>;
+ };
+
+* DMA client
+
+DMA clients connected to the STM32 DMA controller must use the format
+described in the dma.txt file, using a five-cell specifier for each
+channel: a phandle plus four integer cells.
+The four cells in order are:
+
+1. The channel id
+2. The request line number
+3. A 32bit mask specifying the DMA channel configuration which are device
+ dependent:
+ -bit 9: Peripheral Increment Address
+ 0x0: no address increment between transfers
+ 0x1: increment address between transfers
+ -bit 10: Memory Increment Address
+ 0x0: no address increment between transfers
+ 0x1: increment address between transfers
+ -bit 15: Peripheral Increment Offset Size
+ 0x0: offset size is linked to the peripheral bus width
+ 0x1: offset size is fixed to 4 (32-bit alignment)
+ -bit 16-17: Priority level
+ 0x0: low
+ 0x1: medium
+ 0x2: high
+ 0x3: very high
+5. A 32bit mask specifying the DMA FIFO threshold configuration which are device
+ dependent:
+ -bit 0-1: Fifo threshold
+ 0x0: 1/4 full FIFO
+ 0x1: 1/2 full FIFO
+ 0x2: 3/4 full FIFO
+ 0x3: full FIFO

+* Ingenic JZ4780 NAND/BCH
+
+This file documents the device tree bindings for NAND flash devices on the
+JZ4780. NAND devices are connected to the NEMC controller (described in
+memory-controllers/ingenic,jz4780-nemc.txt), and thus NAND device nodes must
+be children of the NEMC node.
+
+Required NAND controller device properties:
+- compatible: Should be set to "ingenic,jz4780-nand".
+- reg: For each bank with a NAND chip attached, should specify a bank number,
+ an offset of 0 and a size of 0x1000000 (i.e. the whole NEMC bank).
+
+Optional NAND controller device properties:
+- ingenic,bch-controller: To make use of the hardware BCH controller, this
+ property must contain a phandle for the BCH controller node. The required
+ properties for this node are described below. If this is not specified,
+ software BCH will be used instead.
+
+Optional children nodes:
+- Individual NAND chips are children of the NAND controller node.
+
+Required children node properties:
+- reg: An integer ranging from 1 to 6 representing the CS line to use.
+
+Optional children node properties:
+- nand-ecc-step-size: ECC block size in bytes.
+- nand-ecc-strength: ECC strength (max number of correctable bits).
+- nand-ecc-mode: String, operation mode of the NAND ecc mode. "hw" by default
+- nand-on-flash-bbt: boolean to enable on flash bbt option, if not present false
+- rb-gpios: GPIO specifier for the busy pin.
+- wp-gpios: GPIO specifier for the write protect pin.
+
+Optional child node of NAND chip nodes:
+- partitions: see Documentation/devicetree/bindings/mtd/partition.txt
+
+Example:
+
+nemc: nemc@13410000 {
+ ...
+
+ nandc: nand-controller@1 {
+ compatible = "ingenic,jz4780-nand";
+ reg = <1 0 0x1000000>; /* Bank 1 */
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ingenic,bch-controller = <&bch>;
+
+ nand@1 {
+ reg = <1>;
+
+ nand-ecc-step-size = <1024>;
+ nand-ecc-strength = <24>;
+ nand-ecc-mode = "hw";
+ nand-on-flash-bbt;
+
+ rb-gpios = <&gpa 20 GPIO_ACTIVE_LOW>;
+ wp-gpios = <&gpf 22 GPIO_ACTIVE_LOW>;
+
+ partitions {
+ #address-cells = <2>;
+ #size-cells = <2>;
+ ...
+ }
+ };
+ };
+};
+
+The BCH controller is a separate SoC component used for error correction on
+NAND devices. The following is a description of the device properties for a
+BCH controller.
+
+Required BCH properties:
+- compatible: Should be set to "ingenic,jz4780-bch".
+- reg: Should specify the BCH controller registers location and length.
+- clocks: Clock for the BCH controller.
+
+Example:
+
+bch: bch@134d0000 {
+ compatible = "ingenic,jz4780-bch";
+ reg = <0x134d0000 0x10000>;

+QCOM SMD RPM REGULATOR
+
+The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
+Because SMD is used as the communication transport mechanism, the RPM resides as
+a subnode of the SMD. As such, the SMD-RPM regulator requires that the SMD and
+RPM nodes be present.
+
+Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.txt for
+information pertaining to the SMD node.

-* Samsung S5M8767 Voltage and Current Regulator
-
-The Samsung S5M8767 is a multi-function device which includes voltage and
-current regulators, rtc, charger controller and other sub-blocks. It is
-interfaced to the host controller using a i2c interface. Each sub-block is
-addressed by the host system using different i2c slave address. This document
-describes the bindings for 'pmic' sub-block of s5m8767.
-
-Required properties:
-- compatible: Should be "samsung,s5m8767-pmic".
-- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
-
-- s5m8767,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
- units for buck2 when changing voltage using gpio dvs. Refer to [1] below
- for additional information.
-
-- s5m8767,pmic-buck3-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
- units for buck3 when changing voltage using gpio dvs. Refer to [1] below
- for additional information.
-
-- s5m8767,pmic-buck4-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
- units for buck4 when changing voltage using gpio dvs. Refer to [1] below
- for additional information.
-
-- s5m8767,pmic-buck-ds-gpios: GPIO specifiers for three host gpio's used
- for selecting GPIO DVS lines. It is one-to-one mapped to dvs gpio lines.
-
-[1] If none of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
- property is specified, the 's5m8767,pmic-buck[2/3/4]-dvs-voltage'
- property should specify atleast one voltage level (which would be a
- safe operating voltage).
-
- If either of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
- property is specified, then all the eight voltage values for the
- 's5m8767,pmic-buck[2/3/4]-dvs-voltage' should be specified.
-
-Optional properties:
-- interrupt-parent: Specifies the phandle of the interrupt controller to which
- the interrupts from s5m8767 are delivered to.
-- interrupts: Interrupt specifiers for two interrupt sources.
- - First interrupt specifier is for 'irq1' interrupt.
- - Second interrupt specifier is for 'alert' interrupt.
-- s5m8767,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
-- s5m8767,pmic-buck3-uses-gpio-dvs: 'buck3' can be controlled by gpio dvs.
-- s5m8767,pmic-buck4-uses-gpio-dvs: 'buck4' can be controlled by gpio dvs.
-
-Additional properties required if either of the optional properties are used:
-
-- s5m8767,pmic-buck234-default-dvs-idx: Default voltage setting selected from
- the possible 8 options selectable by the dvs gpios. The value of this
- property should be between 0 and 7. If not specified or if out of range, the
- default value of this property is set to 0.
-
-- s5m8767,pmic-buck-dvs-gpios: GPIO specifiers for three host gpio's used
- for dvs. The format of the gpio specifier depends in the gpio controller.
-
-Regulators: The regulators of s5m8767 that have to be instantiated should be
-included in a sub-node named 'regulators'. Regulator nodes included in this
-sub-node should be of the format as listed below.
-
- regulator_name {
- ldo1_reg: LDO1 {
- regulator-name = "VDD_ALIVE_1.0V";
- regulator-min-microvolt = <1100000>;
- regulator-max-microvolt = <1100000>;
- regulator-always-on;
- regulator-boot-on;
- op_mode = <1>; /* Normal Mode */
- };
- };
-The above regulator entries are defined in regulator bindings documentation
-except these properties:
- - op_mode: describes the different operating modes of the LDO's with
- power mode change in SOC. The different possible values are,
- 0 - always off mode
- 1 - on in normal mode
- 2 - low power mode
- 3 - suspend mode
- - s5m8767,pmic-ext-control-gpios: (optional) GPIO specifier for one
- GPIO controlling this regulator (enable/disable); This is
- valid only for buck9.
-
-The following are the names of the regulators that the s5m8767 pmic block
-supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
-as per the datasheet of s5m8767.
-
- - LDOn
- - valid values for n are 1 to 28
- - Example: LDO1, LDO2, LDO28
- - BUCKn
- - valid values for n are 1 to 9.
- - Example: BUCK1, BUCK2, BUCK9
-
-The bindings inside the regulator nodes use the standard regulator bindings
-which are documented elsewhere.

+Binding for Samsung S2MPA01 regulator block
+===========================================
+
+This is a part of device tree bindings for S2M family multi-function devices.
+More information can be found in bindings/mfd/sec-core.txt file.
+
+The S2MPA01 device provide buck and LDO regulators.
+
+To register these with regulator framework instantiate under main device node
+a sub-node named "regulators" with more sub-nodes for each regulator using the
+common regulator binding documented in:
+ - Documentation/devicetree/bindings/regulator/regulator.txt
+
+
+Names of regulators supported by S2MPA01 device:
+ - LDOn
+ - valid values for n are 1 to 26
+ - Example: LDO1, LD02, LDO26
+ - BUCKn
+ - valid values for n are 1 to 10.
+ - Example: BUCK1, BUCK2, BUCK9
+Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
+as per the datasheet of device.
+
+
+Optional properties of buck regulator nodes under "regulators" sub-node:
+ - regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
+ (default), 25000, or 50000. May be 0 for disabling the ramp delay on
+ BUCK{1,2,3,4}.
+
+ In the absence of the regulator-ramp-delay property, the default ramp
+ delay will be used.
+
+ Note: Some bucks share the ramp rate setting i.e. same ramp value
+ will be set for a particular group of bucks so provide the same
+ regulator-ramp-delay value for them.
+ Groups sharing ramp rate:
+ - buck{1,6},
+ - buck{2,4},
+ - buck{8,9,10}.
+
+Example:
+
+ s2mpa01_pmic@66 {
+ compatible = "samsung,s2mpa01-pmic";
+ reg = <0x66>;
+
+ regulators {
+ ldo1_reg: LDO1 {

+Binding for Samsung S2M family regulator block
+==============================================
+
+This is a part of device tree bindings for S2M family multi-function devices.
+More information can be found in bindings/mfd/sec-core.txt file.
+
+The S2MPS11/13/14/15 and S2MPU02 devices provide buck and LDO regulators.
+
+To register these with regulator framework instantiate under main device node
+a sub-node named "regulators" with more sub-nodes for each regulator using the
+common regulator binding documented in:
+ - Documentation/devicetree/bindings/regulator/regulator.txt
+
+
+Names of regulators supported by different devices:
+ - LDOn
+ - valid values for n are:
+ - S2MPS11: 1 to 38
+ - S2MPS13: 1 to 40
+ - S2MPS14: 1 to 25
+ - S2MPS15: 1 to 27
+ - S2MPU02: 1 to 28
+ - Example: LDO1, LDO2, LDO28
+ - BUCKn
+ - valid values for n are:
+ - S2MPS11: 1 to 10
+ - S2MPS13: 1 to 10
+ - S2MPS14: 1 to 5
+ - S2MPS15: 1 to 10
+ - S2MPU02: 1 to 7
+ - Example: BUCK1, BUCK2, BUCK9
+Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
+as per the datasheet of device.
+
+
+Optional properties of the nodes under "regulators" sub-node:
+ - regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500,
+ 25000 (default) or 50000.
+
+ Additionally S2MPS11 supports disabling ramp delay for BUCK{2,3,4,6}
+ by setting it to <0>.
+
+ Note: On S2MPS11 some bucks share the ramp rate setting i.e. same ramp value
+ will be set for a particular group of bucks so provide the same
+ regulator-ramp-delay value for them.
+ Groups sharing ramp rate:
+ - buck{1,6},
+ - buck{3,4},
+ - buck{7,8,10}.
+
+ - samsung,ext-control-gpios: On S2MPS14 the LDO10, LDO11 and LDO12 can be
+ configured to external control over GPIO. To turn this feature on this
+ property must be added to the regulator sub-node:
+ - samsung,ext-control-gpios: GPIO specifier for one GPIO
+ controlling this regulator (enable/disable)
+ Example:
+ LDO12 {
+ regulator-name = "V_EMMC_2.8V";
+ regulator-min-microvolt = <2800000>;
+ regulator-max-microvolt = <2800000>;
+ samsung,ext-control-gpios = <&gpk0 2 0>;
+ };
+
+
+Example:
+
+ s2mps11_pmic@66 {
+ compatible = "samsung,s2mps11-pmic";
+ reg = <0x66>;
+
+ regulators {
+ ldo1_reg: LDO1 {
+ regulator-name = "VDD_ABB_3.3V";
+ regulator-min-microvolt = <3300000>;

+ regulator-min-microvolt = <1100000>;
+ regulator-max-microvolt = <1100000>;
+ regulator-always-on;
+ };
+
+ buck1_reg: BUCK1 {
+ regulator-name = "vdd_mif";
+ regulator-min-microvolt = <950000>;

+ - Documentation/devicetree/bindings/regulator/regulator.txt
+
+
+Required properties of the main device node (the parent!):

+ property is specified, the 's5m8767,pmic-buck[2/3/4]-dvs-voltage'
+ property should specify atleast one voltage level (which would be a
+ safe operating voltage).
+
+ If either of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional

+Optional properties of the nodes under "regulators" sub-node:
+ - op_mode: describes the different operating modes of the LDO's with
+ power mode change in SOC. The different possible values are,
+ 0 - always off mode

+ - queue-count : number of delivery and completion queues in the controller
+ - phy-count : number of phys accessible by the controller
+ - interrupts : Interrupts for phys, completion queues, and fatal
+ sources; the interrupts are ordered in 3 groups, as follows:

+ - Completion queue interrupts
+ - Fatal interrupts
+ Phy interrupts : Each phy has 3 interrupt sources:
+ - broadcast
+ - phyup
+ - abnormal
+ The phy interrupts are ordered into groups of 3 per phy
+ (broadcast, phyup, and abnormal) in increasing order.

-
-SRAM nodes
-----------
-
-Each SRAM is described using the mmio-sram bindings documented in
-Documentation/devicetree/bindings/misc/sram.txt
-
-Each SRAM will have SRAM sections that are going to be handled by the
-SRAM controller as subnodes. These sections are represented following

- - allwinner,sun4i-a10-sram-d
-
-Devices using SRAM sections
----------------------------
-
-Some devices need to request to the SRAM controller to map an SRAM for
-their exclusive use.
-
-The relationship between such a device and an SRAM section is
-expressed through the allwinner,sram property, that will take a

+Wakeup M3 IPC Driver
+=====================
+
+The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
+(commonly referred to as Wakeup M3 or CM3) to help with various low power tasks
+that cannot be controlled from the MPU, like suspend/resume and certain deep
+C-states for CPU Idle. Once the wkup_m3_ipc driver uses the wkup_m3_rproc driver
+to boot the wkup_m3, it handles communication with the CM3 using IPC registers
+present in the SoC's control module and a mailbox. The wkup_m3_ipc exposes an
+API to allow the SoC PM code to execute specific PM tasks.
+
+Wkup M3 Device Node:
+====================
+A wkup_m3_ipc device node is used to represent the IPC registers within an
+SoC.
+
+Required properties:
+--------------------
+- compatible: Should be,
+ "ti,am3352-wkup-m3-ipc" for AM33xx SoCs
+ "ti,am4372-wkup-m3-ipc" for AM43xx SoCs
+- reg: Contains the IPC register address space to communicate
+ with the Wakeup M3 processor
+- interrupts: Contains the interrupt information for the wkup_m3
+ interrupt that signals the MPU.
+- ti,rproc: phandle to the wkup_m3 rproc node so the IPC driver
+ can boot it.
+- mboxes: phandles used by IPC framework to get correct mbox
+ channel for communication. Must point to appropriate
+ mbox_wkupm3 child node.
+
+Example:
+--------
+/* AM33xx */
+ l4_wkup: l4_wkup@44c00000 {
+ ...
+
+ scm: scm@210000 {
+ compatible = "ti,am3-scm", "simple-bus";

+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x210000 0x2000>;
+
+ ...
+
+ wkup_m3_ipc: wkup_m3_ipc@1324 {
+ compatible = "ti,am3352-wkup-m3-ipc";

+Allwinnner SoC SRAM controllers
+-----------------------------------------------------
+
+The SRAM controller found on most Allwinner devices is represented by
+a regular node for the SRAM controller itself, with sub-nodes
+reprensenting the SRAM handled by the SRAM controller.
+
+Controller Node
+---------------
+
+Required properties:
+- compatible : "allwinner,sun4i-a10-sram-controller"
+- reg : sram controller register offset + length
+
+SRAM nodes
+----------
+
+Each SRAM is described using the mmio-sram bindings documented in
+Documentation/devicetree/bindings/sram/sram.txt
+
+Each SRAM will have SRAM sections that are going to be handled by the
+SRAM controller as subnodes. These sections are represented following
+once again the representation described in the mmio-sram binding.
+
+The valid sections compatible are:
+ - allwinner,sun4i-a10-sram-a3-a4
+ - allwinner,sun4i-a10-sram-d
+
+Devices using SRAM sections
+---------------------------
+
+Some devices need to request to the SRAM controller to map an SRAM for
+their exclusive use.
+
+The relationship between such a device and an SRAM section is
+expressed through the allwinner,sram property, that will take a
+phandle and an argument.
+
+This valid values for this argument are:
+ - 0: CPU
+ - 1: Device
+
+Example
+-------
+sram-controller@01c00000 {
+ compatible = "allwinner,sun4i-a10-sram-controller";
+ reg = <0x01c00000 0x30>;

+Industrial IIO configfs support
+
+1. Overview
+
+Configfs is a filesystem-based manager of kernel objects. IIO uses some
+objects that could be easily configured using configfs (e.g.: devices,
+triggers).
+
+See Documentation/filesystems/configfs/configfs.txt for more information
+about how configfs works.
+
+2. Usage
+
+In order to use configfs support in IIO we need to select it at compile
+time via CONFIG_IIO_CONFIGFS config option.
+
+Then, mount the configfs filesystem (usually under /config directory):
+
+$ mkdir /config
+$ mount -t configfs none /config
+
+At this point, all default IIO groups will be created and can be accessed
+under /config/iio. Next chapters will describe available IIO configuration
+objects.
+
+3. Software triggers
+
+One of the IIO default configfs groups is the "triggers" group. It is
+automagically accessible when the configfs is mounted and can be found
+under /config/iio/triggers.
+
+IIO software triggers implementation offers support for creating multiple
+trigger types. A new trigger type is usually implemented as a separate
+kernel module following the interface in include/linux/iio/sw_trigger.h:
+
+/*
+ * drivers/iio/trigger/iio-trig-sample.c
+ * sample kernel module implementing a new trigger type
+ */
+#include <linux/iio/sw_trigger.h>
+
+
+static struct iio_sw_trigger *iio_trig_sample_probe(const char *name)
+{
+ /*
+ * This allocates and registers an IIO trigger plus other
+ * trigger type specific initialization.
+ */
+}
+
+static int iio_trig_hrtimer_remove(struct iio_sw_trigger *swt)
+{
+ /*
+ * This undoes the actions in iio_trig_sample_probe
+ */
+}
+
+static const struct iio_sw_trigger_ops iio_trig_sample_ops = {
+ .probe = iio_trig_sample_probe,
+ .remove = iio_trig_sample_remove,
+};
+
+static struct iio_sw_trigger_type iio_trig_sample = {
+ .name = "trig-sample",
+ .owner = THIS_MODULE,
+ .ops = &iio_trig_sample_ops,
+};
+
+module_iio_sw_trigger_driver(iio_trig_sample);
+
+Each trigger type has its own directory under /config/iio/triggers. Loading
+iio-trig-sample module will create 'trig-sample' trigger type directory
+/config/iio/triggers/trig-sample.
+
+We support the following interrupt sources (trigger types):
+ * hrtimer, uses high resolution timers as interrupt source
+
+3.1 Hrtimer triggers creation and destruction
+
+Loading iio-trig-hrtimer module will register hrtimer trigger types allowing
+users to create hrtimer triggers under /config/iio/triggers/hrtimer.
+
+e.g:
+
+$ mkdir /config/triggers/hrtimer/instance1
+$ rmdir /config/triggers/hrtimer/instance1
+
+Each trigger can have one or more attributes specific to the trigger type.
+
+3.2 "hrtimer" trigger types attributes
+
+"hrtimer" trigger type doesn't have any configurable attribute from /config dir.
+It does introduce the sampling_frequency attribute to trigger directory.

2. DLM Locks for management

+There are three groups of locks for managing the device:
2.1 Bitmap lock resource (bm_lockres)
- The bm_lockres protects individual node bitmaps. They are named in the
- form bitmap001 for node 1, bitmap002 for node and so on. When a node
- joins the cluster, it acquires the lock in PW mode and it stays so
- during the lifetime the node is part of the cluster. The lock resource
- number is based on the slot number returned by the DLM subsystem. Since
- DLM starts node count from one and bitmap slots start from zero, one is

+ The bm_lockres protects individual node bitmaps. They are named in
+ the form bitmap000 for node 1, bitmap001 for node 2 and so on. When a
+ node joins the cluster, it acquires the lock in PW mode and it stays
+ so during the lifetime the node is part of the cluster. The lock
+ resource number is based on the slot number returned by the DLM
+ subsystem. Since DLM starts node count from one and bitmap slots
+ start from zero, one is subtracted from the DLM slot number to arrive
+ at the bitmap slot number.
+
+ The LVB of the bitmap lock for a particular node records the range
+ of sectors that are being re-synced by that node. No other
+ node may write to those sectors. This is used when a new nodes
+ joins the cluster.
+
+2.2 Message passing locks
+
+ Each node has to communicate with other nodes when starting or ending
+ resync, and for metadata superblock updates. This communication is
+ managed through three locks: "token", "message", and "ack", together
+ with the Lock Value Block (LVB) of one of the "message" lock.
+
+2.3 new-device management
+
+ A single lock: "no-new-dev" is used to co-ordinate the addition of
+ new devices - this must be synchronized across the array.
+ Normally all nodes hold a concurrent-read lock on this device.
3. Communication
-Each node has to communicate with other nodes when starting or ending
-resync, and metadata superblock updates.
+ Messages can be broadcast to all nodes, and the sender waits for all
+ other nodes to acknowledge the message before proceeding. Only one
+ message can be processed at a time.
3.1 Message Types
- There are 3 types, of messages which are passed
+ There are six types of messages which are passed:
- 3.1.1 METADATA_UPDATED: informs other nodes that the metadata has been
- updated, and the node must re-read the md superblock. This is performed
- synchronously.
+ 3.1.1 METADATA_UPDATED: informs other nodes that the metadata has
+ been updated, and the node must re-read the md superblock. This is
+ performed synchronously. It is primarily used to signal device
+ failure.
- 3.1.2 RESYNC: informs other nodes that a resync is initiated or ended
- so that each node may suspend or resume the region.
+ 3.1.2 RESYNCING: informs other nodes that a resync is initiated or
+ ended so that each node may suspend or resume the region. Each
+ RESYNCING message identifies a range of the devices that the
+ sending node is about to resync. This over-rides any pervious
+ notification from that node: only one ranged can be resynced at a
+ time per-node.
+
+ 3.1.3 NEWDISK: informs other nodes that a device is being added to
+ the array. Message contains an identifier for that device. See
+ below for further details.
+
+ 3.1.4 REMOVE: A failed or spare device is being removed from the
+ array. The slot-number of the device is included in the message.
+
+ 3.1.5 RE_ADD: A failed device is being re-activated - the assumption
+ is that it has been determined to be working again.
+
+ 3.1.6 BITMAP_NEEDS_SYNC: if a node is stopped locally but the bitmap
+ isn't clean, then another node is informed to take the ownership of
+ resync.
3.2 Communication mechanism
The DLM LVB is used to communicate within nodes of the cluster. There
are three resources used for the purpose:
- 3.2.1 Token: The resource which protects the entire communication
+ 3.2.1 token: The resource which protects the entire communication
system. The node having the token resource is allowed to

+
+ There are 17 call-backs which the md core can make to the cluster
+ module. Understanding these can give a good overview of the whole
+ process.
+
+6.1 join(nodes) and leave()
+
+ These are called when an array is started with a clustered bitmap,
+ and when the array is stopped. join() ensures the cluster is
+ available and initializes the various resources.
+ Only the first 'nodes' nodes in the cluster can use the array.
+
+6.2 slot_number()
+
+ Reports the slot number advised by the cluster infrastructure.
+ Range is from 0 to nodes-1.
+
+6.3 resync_info_update()
+
+ This updates the resync range that is stored in the bitmap lock.
+ The starting point is updated as the resync progresses. The
+ end point is always the end of the array.
+ It does *not* send a RESYNCING message.
+
+6.4 resync_start(), resync_finish()
+
+ These are called when resync/recovery/reshape starts or stops.
+ They update the resyncing range in the bitmap lock and also
+ send a RESYNCING message. resync_start reports the whole
+ array as resyncing, resync_finish reports none of it.
+
+ resync_finish() also sends a BITMAP_NEEDS_SYNC message which
+ allows some other node to take over.
+
+6.5 metadata_update_start(), metadata_update_finish(),
+ metadata_update_cancel().
+
+ metadata_update_start is used to get exclusive access to
+ the metadata. If a change is still needed once that access is
+ gained, metadata_update_finish() will send a METADATA_UPDATE
+ message to all other nodes, otherwise metadata_update_cancel()
+ can be used to release the lock.
+
+6.6 area_resyncing()
+
+ This combines two elements of functionality.
+
+ Firstly, it will check if any node is currently resyncing
+ anything in a given range of sectors. If any resync is found,
+ then the caller will avoid writing or read-balancing in that
+ range.
+
+ Secondly, while node recovery is happening it reports that
+ all areas are resyncing for READ requests. This avoids races
+ between the cluster-filesystem and the cluster-RAID handling
+ a node failure.
+
+6.7 add_new_disk_start(), add_new_disk_finish(), new_disk_ack()
+
+ These are used to manage the new-disk protocol described above.
+ When a new device is added, add_new_disk_start() is called before
+ it is bound to the array and, if that succeeds, add_new_disk_finish()
+ is called the device is fully added.
+
+ When a device is added in acknowledgement to a previous
+ request, or when the device is declared "unavailable",
+ new_disk_ack() is called.
+
+6.8 remove_disk()
+
+ This is called when a spare or failed device is removed from
+ the array. It causes a REMOVE message to be send to other nodes.
+
+6.9 gather_bitmaps()
+
+ This sends a RE_ADD message to all other nodes and then
+ gathers bitmap information from all bitmaps. This combined
+ bitmap is then used to recovery the re-added device.
+
+6.10 lock_all_bitmaps() and unlock_all_bitmaps()
+
+ These are called when change bitmap to none. If a node plans
+ to clear the cluster raid's bitmap, it need to make sure no other
+ nodes are using the raid which is achieved by lock all bitmap
+ locks within the cluster, and also those locks are unlocked
+ accordingly.

-Linux kernel media framework
-============================
-
-This document describes the Linux kernel media framework, its data structures,
-functions and their usage.
-
-
-Introduction
-------------
-
-The media controller API is documented in DocBook format in
-Documentation/DocBook/media/v4l/media-controller.xml. This document will focus
-on the kernel-side implementation of the media framework.
-
-
-Abstract media device model
----------------------------
-
-Discovering a device internal topology, and configuring it at runtime, is one
-of the goals of the media framework. To achieve this, hardware devices are
-modelled as an oriented graph of building blocks called entities connected
-through pads.
-
-An entity is a basic media hardware building block. It can correspond to
-a large variety of logical blocks such as physical hardware devices
-(CMOS sensor for instance), logical hardware devices (a building block
-in a System-on-Chip image processing pipeline), DMA channels or physical
-connectors.
-
-A pad is a connection endpoint through which an entity can interact with
-other entities. Data (not restricted to video) produced by an entity
-flows from the entity's output to one or more entity inputs. Pads should
-not be confused with physical pins at chip boundaries.
-
-A link is a point-to-point oriented connection between two pads, either
-on the same entity or on different entities. Data flows from a source
-pad to a sink pad.
-
-
-Media device
-------------
-
-A media device is represented by a struct media_device instance, defined in
-include/media/media-device.h. Allocation of the structure is handled by the
-media device driver, usually by embedding the media_device instance in a
-larger driver-specific structure.
-
-Drivers register media device instances by calling
-
- media_device_register(struct media_device *mdev);
-
-The caller is responsible for initializing the media_device structure before
-registration. The following fields must be set:
-
- - dev must point to the parent device (usually a pci_dev, usb_interface or
- platform_device instance).
-
- - model must be filled with the device model name as a NUL-terminated UTF-8
- string. The device/model revision must not be stored in this field.
-
-The following fields are optional:
-
- - serial is a unique serial number stored as a NUL-terminated ASCII string.
- The field is big enough to store a GUID in text form. If the hardware
- doesn't provide a unique serial number this field must be left empty.
-
- - bus_info represents the location of the device in the system as a
- NUL-terminated ASCII string. For PCI/PCIe devices bus_info must be set to
- "PCI:" (or "PCIe:") followed by the value of pci_name(). For USB devices,
- the usb_make_path() function must be used. This field is used by
- applications to distinguish between otherwise identical devices that don't
- provide a serial number.
-
- - hw_revision is the hardware device revision in a driver-specific format.
- When possible the revision should be formatted with the KERNEL_VERSION
- macro.
-
- - driver_version is formatted with the KERNEL_VERSION macro. The version
- minor must be incremented when new features are added to the userspace API
- without breaking binary compatibility. The version major must be
- incremented when binary compatibility is broken.
-
-Upon successful registration a character device named media[0-9]+ is created.
-The device major and minor numbers are dynamic. The model name is exported as
-a sysfs attribute.
-
-Drivers unregister media device instances by calling
-
- media_device_unregister(struct media_device *mdev);
-
-Unregistering a media device that hasn't been registered is *NOT* safe.
-
-
-Entities, pads and links
-------------------------
-
-- Entities
-
-Entities are represented by a struct media_entity instance, defined in
-include/media/media-entity.h. The structure is usually embedded into a
-higher-level structure, such as a v4l2_subdev or video_device instance,
-although drivers can allocate entities directly.
-
-Drivers initialize entities by calling
-
- media_entity_init(struct media_entity *entity, u16 num_pads,
- struct media_pad *pads, u16 extra_links);
-
-The media_entity name, type, flags, revision and group_id fields can be
-initialized before or after calling media_entity_init. Entities embedded in
-higher-level standard structures can have some of those fields set by the
-higher-level framework.
-
-As the number of pads is known in advance, the pads array is not allocated
-dynamically but is managed by the entity driver. Most drivers will embed the
-pads array in a driver-specific structure, avoiding dynamic allocation.
-
-Drivers must set the direction of every pad in the pads array before calling
-media_entity_init. The function will initialize the other pads fields.
-
-Unlike the number of pads, the total number of links isn't always known in
-advance by the entity driver. As an initial estimate, media_entity_init
-pre-allocates a number of links equal to the number of pads plus an optional
-number of extra links. The links array will be reallocated if it grows beyond
-the initial estimate.
-
-Drivers register entities with a media device by calling
-
- media_device_register_entity(struct media_device *mdev,
- struct media_entity *entity);
-
-Entities are identified by a unique positive integer ID. Drivers can provide an
-ID by filling the media_entity id field prior to registration, or request the
-media controller framework to assign an ID automatically. Drivers that provide
-IDs manually must ensure that all IDs are unique. IDs are not guaranteed to be
-contiguous even when they are all assigned automatically by the framework.
-
-Drivers unregister entities by calling
-
- media_device_unregister_entity(struct media_entity *entity);
-
-Unregistering an entity will not change the IDs of the other entities, and the
-ID will never be reused for a newly registered entity.
-
-When a media device is unregistered, all its entities are unregistered
-automatically. No manual entities unregistration is then required.
-
-Drivers free resources associated with an entity by calling
-
- media_entity_cleanup(struct media_entity *entity);
-
-This function must be called during the cleanup phase after unregistering the
-entity. Note that the media_entity instance itself must be freed explicitly by
-the driver if required.
-
-Entities have flags that describe the entity capabilities and state.
-
- MEDIA_ENT_FL_DEFAULT indicates the default entity for a given type.
- This can be used to report the default audio and video devices or the
- default camera sensor.
-
-Logical entity groups can be defined by setting the group ID of all member
-entities to the same non-zero value. An entity group serves no purpose in the
-kernel, but is reported to userspace during entities enumeration. The group_id
-field belongs to the media device driver and must not by touched by entity
-drivers.
-
-Media device drivers should define groups if several entities are logically
-bound together. Example usages include reporting
-
- - ALSA, VBI and video nodes that carry the same media stream
- - lens and flash controllers associated with a sensor
-
-- Pads
-
-Pads are represented by a struct media_pad instance, defined in
-include/media/media-entity.h. Each entity stores its pads in a pads array
-managed by the entity driver. Drivers usually embed the array in a
-driver-specific structure.
-
-Pads are identified by their entity and their 0-based index in the pads array.
-Both information are stored in the media_pad structure, making the media_pad
-pointer the canonical way to store and pass link references.
-
-Pads have flags that describe the pad capabilities and state.
-
- MEDIA_PAD_FL_SINK indicates that the pad supports sinking data.
- MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data.
-
-One and only one of MEDIA_PAD_FL_SINK and MEDIA_PAD_FL_SOURCE must be set for
-each pad.
-
-- Links
-
-Links are represented by a struct media_link instance, defined in
-include/media/media-entity.h. Each entity stores all links originating at or
-targeting any of its pads in a links array. A given link is thus stored
-twice, once in the source entity and once in the target entity. The array is
-pre-allocated and grows dynamically as needed.
-
-Drivers create links by calling
-
- media_entity_create_link(struct media_entity *source, u16 source_pad,
- struct media_entity *sink, u16 sink_pad,
- u32 flags);
-
-An entry in the link array of each entity is allocated and stores pointers
-to source and sink pads.
-
-Links have flags that describe the link capabilities and state.
-
- MEDIA_LNK_FL_ENABLED indicates that the link is enabled and can be used
- to transfer media data. When two or more links target a sink pad, only
- one of them can be enabled at a time.
- MEDIA_LNK_FL_IMMUTABLE indicates that the link enabled state can't be
- modified at runtime. If MEDIA_LNK_FL_IMMUTABLE is set, then
- MEDIA_LNK_FL_ENABLED must also be set since an immutable link is always
- enabled.
-
-
-Graph traversal
----------------
-
-The media framework provides APIs to iterate over entities in a graph.
-
-To iterate over all entities belonging to a media device, drivers can use the
-media_device_for_each_entity macro, defined in include/media/media-device.h.
-
- struct media_entity *entity;
-
- media_device_for_each_entity(entity, mdev) {
- /* entity will point to each entity in turn */
- ...
- }
-
-Drivers might also need to iterate over all entities in a graph that can be
-reached only through enabled links starting at a given entity. The media
-framework provides a depth-first graph traversal API for that purpose.
-
-Note that graphs with cycles (whether directed or undirected) are *NOT*
-supported by the graph traversal API. To prevent infinite loops, the graph
-traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH,
-currently defined as 16.
-
-Drivers initiate a graph traversal by calling
-
- media_entity_graph_walk_start(struct media_entity_graph *graph,
- struct media_entity *entity);
-
-The graph structure, provided by the caller, is initialized to start graph
-traversal at the given entity.
-
-Drivers can then retrieve the next entity by calling
-
- media_entity_graph_walk_next(struct media_entity_graph *graph);
-
-When the graph traversal is complete the function will return NULL.
-
-Graph traversal can be interrupted at any moment. No cleanup function call is
-required and the graph structure can be freed normally.
-
-Helper functions can be used to find a link between two given pads, or a pad
-connected to another pad through an enabled link
-
- media_entity_find_link(struct media_pad *source,
- struct media_pad *sink);
-
- media_entity_remote_pad(struct media_pad *pad);
-
-Refer to the kerneldoc documentation for more information.
-
-
-Use count and power handling
-----------------------------
-
-Due to the wide differences between drivers regarding power management needs,
-the media controller does not implement power management. However, the
-media_entity structure includes a use_count field that media drivers can use to
-track the number of users of every entity for power management needs.
-
-The use_count field is owned by media drivers and must not be touched by entity
-drivers. Access to the field must be protected by the media device graph_mutex
-lock.
-
-
-Links setup
------------
-
-Link properties can be modified at runtime by calling
-
- media_entity_setup_link(struct media_link *link, u32 flags);
-
-The flags argument contains the requested new link flags.
-
-The only configurable property is the ENABLED link flag to enable/disable a
-link. Links marked with the IMMUTABLE link flag can not be enabled or disabled.
-
-When a link is enabled or disabled, the media framework calls the
-link_setup operation for the two entities at the source and sink of the link,
-in that order. If the second link_setup call fails, another link_setup call is
-made on the first entity to restore the original link flags.
-
-Media device drivers can be notified of link setup operations by setting the
-media_device::link_notify pointer to a callback function. If provided, the
-notification callback will be called before enabling and after disabling
-links.
-
-Entity drivers must implement the link_setup operation if any of their links
-is non-immutable. The operation must either configure the hardware or store
-the configuration information to be applied later.
-
-Link configuration must not have any side effect on other links. If an enabled
-link at a sink pad prevents another link at the same pad from being enabled,
-the link_setup operation must return -EBUSY and can't implicitly disable the
-first enabled link.
-
-
-Pipelines and media streams
----------------------------
-
-When starting streaming, drivers must notify all entities in the pipeline to
-prevent link states from being modified during streaming by calling
-
- media_entity_pipeline_start(struct media_entity *entity,
- struct media_pipeline *pipe);
-
-The function will mark all entities connected to the given entity through
-enabled links, either directly or indirectly, as streaming.
-
-The media_pipeline instance pointed to by the pipe argument will be stored in
-every entity in the pipeline. Drivers should embed the media_pipeline structure
-in higher-level pipeline structures and can then access the pipeline through
-the media_entity pipe field.
-
-Calls to media_entity_pipeline_start() can be nested. The pipeline pointer must
-be identical for all nested calls to the function.
-
-media_entity_pipeline_start() may return an error. In that case, it will
-clean up any of the changes it did by itself.
-
-When stopping the stream, drivers must notify the entities with
-
- media_entity_pipeline_stop(struct media_entity *entity);
-
-If multiple calls to media_entity_pipeline_start() have been made the same
-number of media_entity_pipeline_stop() calls are required to stop streaming. The
-media_entity pipe field is reset to NULL on the last nested stop call.
-
-Link configuration will fail with -EBUSY by default if either end of the link is
-a streaming entity. Links that can be modified while streaming must be marked
-with the MEDIA_LNK_FL_DYNAMIC flag.
-
-If other operations need to be disallowed on streaming entities (such as
-changing entities configuration parameters) drivers can explicitly check the
-media_entity stream_count field to find out if an entity is streaming. This
-operation must be done with the media_device graph_mutex held.
-
-
-Link validation
----------------
-
-Link validation is performed by media_entity_pipeline_start() for any
-entity which has sink pads in the pipeline. The
-media_entity::link_validate() callback is used for that purpose. In
-link_validate() callback, entity driver should check that the properties of
-the source pad of the connected entity and its own sink pad match. It is up
-to the type of the entity (and in the end, the properties of the hardware)
-what matching actually means.
-
-Subsystems should facilitate link validation by providing subsystem specific
-helper functions to provide easy access for commonly needed information, and
-in the end provide a way to use driver-specific callbacks.

-== compound_lock, get_user_pages and put_page ==
+== Refcounts and transparent huge pages ==
+
+Refcounting on THP is mostly consistent with refcounting on other compound
+pages:
+
+ - get_page()/put_page() and GUP operate in head page's ->_count.
+
+ - ->_count in tail pages is always zero: get_page_unless_zero() never
+ succeed on tail pages.
+
+ - map/unmap of the pages with PTE entry increment/decrement ->_mapcount
+ on relevant sub-page of the compound page.
+
+ - map/unmap of the whole compound page accounted in compound_mapcount
+ (stored in first tail page).
+
+PageDoubleMap() indicates that ->_mapcount in all subpages is offset up by one.
+This additional reference is required to get race-free detection of unmap of
+subpages when we have them mapped with both PMDs and PTEs.
+
+This is optimization required to lower overhead of per-subpage mapcount
+tracking. The alternative is alter ->_mapcount in all subpages on each
+map/unmap of the whole compound page.
+
+We set PG_double_map when a PMD of the page got split for the first time,
+but still have PMD mapping. The addtional references go away with last
+compound_mapcount.
split_huge_page internally has to distribute the refcounts in the head
-page to the tail pages before clearing all PG_head/tail bits from the
-page structures. It can do that easily for refcounts taken by huge pmd
-mappings. But the GUI API as created by hugetlbfs (that returns head
-and tail pages if running get_user_pages on an address backed by any
-hugepage), requires the refcount to be accounted on the tail pages and
-not only in the head pages, if we want to be able to run
-split_huge_page while there are gup pins established on any tail
-page. Failure to be able to run split_huge_page if there's any gup pin
-on any tail page, would mean having to split all hugepages upfront in
-get_user_pages which is unacceptable as too many gup users are
-performance critical and they must work natively on hugepages like
-they work natively on hugetlbfs already (hugetlbfs is simpler because
-hugetlbfs pages cannot be split so there wouldn't be requirement of
-accounting the pins on the tail pages for hugetlbfs). If we wouldn't
-account the gup refcounts on the tail pages during gup, we won't know
-anymore which tail page is pinned by gup and which is not while we run
-split_huge_page. But we still have to add the gup pin to the head page
-too, to know when we can free the compound page in case it's never
-split during its lifetime. That requires changing not just
-get_page, but put_page as well so that when put_page runs on a tail
-page (and only on a tail page) it will find its respective head page,
-and then it will decrease the head page refcount in addition to the
-tail page refcount. To obtain a head page reliably and to decrease its
-refcount without race conditions, put_page has to serialize against
-__split_huge_page_refcount using a special per-page lock called
-compound_lock.
+page to the tail pages before clearing all PG_head/tail bits from the page
+structures. It can be done easily for refcounts taken by page table
+entries. But we don't have enough information on how to distribute any
+additional pins (i.e. from get_user_pages). split_huge_page() fails any
+requests to split pinned huge page: it expects page count to be equal to
+sum of mapcount of all sub-pages plus one (split_huge_page caller must
+have reference for head page).
+
+split_huge_page uses migration entries to stabilize page->_count and
+page->_mapcount.
+
+We safe against physical memory scanners too: the only legitimate way
+scanner can get reference to a page is get_page_unless_zero().
+
+All tail pages has zero ->_count until atomic_add(). It prevent scanner
+from geting reference to tail page up to the point. After the atomic_add()
+we don't care about ->_count value. We already known how many references
+with should uncharge from head page.
+
+For head page get_page_unless_zero() will succeed and we don't mind. It's
+clear where reference should go after split: it will stay on head page.
+
+Note that split_huge_pmd() doesn't have any limitation on refcounting:
+pmd can be split at any point and never fails.
+
+== Partial unmap and deferred_split_huge_page() ==
+
+Unmapping part of THP (with munmap() or other way) is not going to free
+memory immediately. Instead, we detect that a subpage of THP is not in use
+in page_remove_rmap() and queue the THP for splitting if memory pressure
+comes. Splitting will free up unused subpages.
+
+Splitting the page right away is not an option due to locking context in
+the place where we can detect partial unmap. It's also might be
+counterproductive since in many cases partial unmap unmap happens during
+exit(2) if an THP crosses VMA boundary.
+
+Function deferred_split_huge_page() is used to queue page for splitting.
+The splitting itself will happen when we get memory pressure via shrinker
+interface.

+ * At present, all PowerPC 400-class processors share a similar TLB

+ * and ITLB, respectively (see "mmu.h" for definitions).
+ *
+ * There are several potential gotchas here. The 40x hardware TLBLO

+ * Where possible we make the Linux PTE bits match up with this
+ *
+ * - bits 20 and 21 must be cleared, because we use 4k pages (40x can
+ * support down to 1k pages), this is done in the TLBMiss exception
+ * handler.
+ * - We use only zones 0 (for kernel pages) and 1 (for user pages)
+ * of the 16 available. Bit 24-26 of the TLB are cleared in the TLB
+ * miss handler. Bit 27 is PAGE_USER, thus selecting the correct
+ * zone.
+ * - PRESENT *must* be in the bottom two bits because swap cache
+ * entries use the top 30 bits. Because 40x doesn't support SMP
+ * anyway, M is irrelevant so we borrow it for PAGE_PRESENT. Bit 30
+ * is cleared in the TLB miss handler before the TLB entry is loaded.
+ * - All other bits of the PTE are loaded into TLBLO without
+ * modification, leaving us only the bits 20, 21, 24, 25, 26, 30 for
+ * software PTE bits. We actually use use bits 21, 24, 25, and

+ * Because of the 3 word TLB entries to support 36-bit addressing,
+ * the attribute are difficult to map in such a fashion that they
+ * are easily loaded during exception processing. I decided to
+ * organize the entry so the ERPN is the only portion in the
+ * upper word of the PTE and the attribute bits below are packed
+ * in as sensibly as they can be in the area below a 4KB page size
+ * oriented RPN. This at least makes it easy to load the RPN and
+ * ERPN fields in the TLB. -Matt
+ *
+ * This isn't entirely true anymore, at least some bits are now
+ * easier to move into the TLB from the PTE. -BenH.
+ *
+ * Note that these bits preclude future use of a page size
+ * less than 4KB.
+ *
+ *
+ * PPC 440 core has following TLB attribute fields;
+ *
+ * TLB1:
+ * 0 1 2 3 4 ... 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
+ * RPN................................. - - - - - - ERPN.......
+ *
+ * TLB2:
+ * 0 1 2 3 4 ... 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
+ * - - - - - - U0 U1 U2 U3 W I M G E - UX UW UR SX SW SR
+ *
+ * Newer 440 cores (440x6 as used on AMCC 460EX/460GT) have additional
+ * TLB2 storage attibute fields. Those are:
+ *
+ * TLB2:
+ * 0...10 11 12 13 14 15 16...31
+ * no change WL1 IL1I IL1D IL2I IL2D no change
+ *
+ * There are some constrains and options, to decide mapping software bits
+ * into TLB entry.
+ *
+ * - PRESENT *must* be in the bottom three bits because swap cache
+ * entries use the top 29 bits for TLB2.
+ *
+ * - CACHE COHERENT bit (M) has no effect on original PPC440 cores,
+ * because it doesn't support SMP. However, some later 460 variants
+ * have -some- form of SMP support and so I keep the bit there for
+ * future use
+ *
+ * With the PPC 44x Linux implementation, the 0-11th LSBs of the PTE are used
+ * for memory protection related functions (see PTE structure in
+ * include/asm-ppc/mmu.h). The _PAGE_XXX definitions in this file map to the
+ * above bits. Note that the bit values are CPU specific, not architecture
+ * specific.
+ *
+ * The kernel PTE entry holds an arch-dependent swp_entry structure under
+ * certain situations. In other words, in such situations some portion of
+ * the PTE bits are used as a swp_entry. In the PPC implementation, the
+ * 3-24th LSB are shared with swp_entry, however the 0-2nd three LSB still
+ * hold protection values. That means the three protection bits are
+ * reserved for both PTE and SWAP entry at the most significant three
+ * LSBs.
+ *
+ * There are three protection bits available for SWAP entry:
+ * _PAGE_PRESENT
+ * _PAGE_HASHPTE (if HW has)
+ *
+ * So those three bits have to be inside of 0-2nd LSB of PTE.

- * At present, all PowerPC 400-class processors share a similar TLB
- * architecture. The instruction and data sides share a unified,
- * 64-entry, fully-associative TLB which is maintained totally under
- * software control. In addition, the instruction side has a
- * hardware-managed, 4-entry, fully-associative TLB which serves as a
- * first level to the shared TLB. These two TLBs are known as the UTLB
- * and ITLB, respectively (see "mmu.h" for definitions).
- *
- * There are several potential gotchas here. The 40x hardware TLBLO
- * field looks like this:
- *
- * 0 1 2 3 4 ... 18 19 20 21 22 23 24 25 26 27 28 29 30 31
- * RPN..................... 0 0 EX WR ZSEL....... W I M G
- *
- * Where possible we make the Linux PTE bits match up with this
- *
- * - bits 20 and 21 must be cleared, because we use 4k pages (40x can
- * support down to 1k pages), this is done in the TLBMiss exception
- * handler.
- * - We use only zones 0 (for kernel pages) and 1 (for user pages)
- * of the 16 available. Bit 24-26 of the TLB are cleared in the TLB
- * miss handler. Bit 27 is PAGE_USER, thus selecting the correct
- * zone.
- * - PRESENT *must* be in the bottom two bits because swap cache
- * entries use the top 30 bits. Because 40x doesn't support SMP
- * anyway, M is irrelevant so we borrow it for PAGE_PRESENT. Bit 30
- * is cleared in the TLB miss handler before the TLB entry is loaded.
- * - All other bits of the PTE are loaded into TLBLO without
- * modification, leaving us only the bits 20, 21, 24, 25, 26, 30 for
- * software PTE bits. We actually use use bits 21, 24, 25, and
- * 30 respectively for the software bits: ACCESSED, DIRTY, RW, and

- * Definitions for PPC440
- *
- * Because of the 3 word TLB entries to support 36-bit addressing,
- * the attribute are difficult to map in such a fashion that they
- * are easily loaded during exception processing. I decided to
- * organize the entry so the ERPN is the only portion in the
- * upper word of the PTE and the attribute bits below are packed
- * in as sensibly as they can be in the area below a 4KB page size
- * oriented RPN. This at least makes it easy to load the RPN and
- * ERPN fields in the TLB. -Matt
- *
- * This isn't entirely true anymore, at least some bits are now
- * easier to move into the TLB from the PTE. -BenH.
- *
- * Note that these bits preclude future use of a page size
- * less than 4KB.
- *
- *
- * PPC 440 core has following TLB attribute fields;
- *
- * TLB1:
- * 0 1 2 3 4 ... 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
- * RPN................................. - - - - - - ERPN.......
- *
- * TLB2:
- * 0 1 2 3 4 ... 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
- * - - - - - - U0 U1 U2 U3 W I M G E - UX UW UR SX SW SR
- *
- * Newer 440 cores (440x6 as used on AMCC 460EX/460GT) have additional
- * TLB2 storage attibute fields. Those are:
- *
- * TLB2:
- * 0...10 11 12 13 14 15 16...31
- * no change WL1 IL1I IL1D IL2I IL2D no change
- *
- * There are some constrains and options, to decide mapping software bits
- * into TLB entry.
- *
- * - PRESENT *must* be in the bottom three bits because swap cache
- * entries use the top 29 bits for TLB2.
- *
- * - CACHE COHERENT bit (M) has no effect on original PPC440 cores,
- * because it doesn't support SMP. However, some later 460 variants
- * have -some- form of SMP support and so I keep the bit there for
- * future use
- *
- * With the PPC 44x Linux implementation, the 0-11th LSBs of the PTE are used
- * for memory protection related functions (see PTE structure in
- * include/asm-ppc/mmu.h). The _PAGE_XXX definitions in this file map to the
- * above bits. Note that the bit values are CPU specific, not architecture
- * specific.
- *
- * The kernel PTE entry holds an arch-dependent swp_entry structure under
- * certain situations. In other words, in such situations some portion of
- * the PTE bits are used as a swp_entry. In the PPC implementation, the
- * 3-24th LSB are shared with swp_entry, however the 0-2nd three LSB still
- * hold protection values. That means the three protection bits are
- * reserved for both PTE and SWAP entry at the most significant three
- * LSBs.
- *
- * There are three protection bits available for SWAP entry:
- * _PAGE_PRESENT
- * _PAGE_HASHPTE (if HW has)
- *
- * So those three bits have to be inside of 0-2nd LSB of PTE.

- * register when the TLB entry is loaded. We will use bit 27 for guard, since
- * that is where it exists in the MD_TWC, and bit 26 for writethrough.
- * These will get masked from the level 2 descriptor at TLB load time, and
- * copied to the MD_TWC before it gets loaded.
- * Large page sizes added. We currently support two sizes, 4K and 8M.

-/* AMD hw uses four ACPI control methods:
- * 1. ATIF
- * ARG0: (ACPI_INTEGER) function code
- * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
- * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
- * ATIF provides an entry point for the gfx driver to interact with the sbios.
- * The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom
- * notification. Which notification is used as indicated by the ATIF Control
- * Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or
- * a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS
- * to identify pending System BIOS requests and associated parameters. For
- * example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver
- * will perform display device detection and invoke ATIF Control Method
- * SELECT_ACTIVE_DISPLAYS.
- *
- * 2. ATPX
- * ARG0: (ACPI_INTEGER) function code
- * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
- * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
- * ATPX methods are used on PowerXpress systems to handle mux switching and
- * discrete GPU power control.
- *
- * 3. ATRM
- * ARG0: (ACPI_INTEGER) offset of vbios rom data
- * ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K).
- * OUTPUT: (ACPI_BUFFER) output buffer
- * ATRM provides an interfacess to access the discrete GPU vbios image on
- * PowerXpress systems with multiple GPUs.
- *
- * 4. ATCS
- * ARG0: (ACPI_INTEGER) function code
- * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
- * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
- * ATCS provides an interface to AMD chipset specific functionality.

+/* AMD hw uses four ACPI control methods:
+ * 1. ATIF
+ * ARG0: (ACPI_INTEGER) function code
+ * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
+ * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
+ * ATIF provides an entry point for the gfx driver to interact with the sbios.
+ * The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom
+ * notification. Which notification is used as indicated by the ATIF Control
+ * Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or
+ * a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS
+ * to identify pending System BIOS requests and associated parameters. For
+ * example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver
+ * will perform display device detection and invoke ATIF Control Method
+ * SELECT_ACTIVE_DISPLAYS.
+ *
+ * 2. ATPX
+ * ARG0: (ACPI_INTEGER) function code
+ * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
+ * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
+ * ATPX methods are used on PowerXpress systems to handle mux switching and
+ * discrete GPU power control.
+ *
+ * 3. ATRM
+ * ARG0: (ACPI_INTEGER) offset of vbios rom data
+ * ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K).
+ * OUTPUT: (ACPI_BUFFER) output buffer
+ * ATRM provides an interfacess to access the discrete GPU vbios image on
+ * PowerXpress systems with multiple GPUs.
+ *
+ * 4. ATCS
+ * ARG0: (ACPI_INTEGER) function code
+ * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
+ * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
+ * ATCS provides an interface to AMD chipset specific functionality.

+ *
+ * Based on the helper callbacks implemented by @connector in struct

+ *
+ * The basic procedure is as follows
+ *
+ * 1. All modes currently on the connector's modes list are marked as stale
+ *
+ * 2. New modes are added to the connector's probed_modes list with
+ * drm_mode_probed_add(). New modes start their life with status as OK.
+ * Modes are added from a single source using the following priority order.
+ *
+ * - debugfs 'override_edid' (used for testing only)
+ * - firmware EDID (drm_load_edid_firmware())
+ * - connector helper ->get_modes() vfunc
+ * - if the connector status is connector_status_connected, standard
+ * VESA DMT modes up to 1024x768 are automatically added
+ * (drm_add_modes_noedid())
+ *
+ * Finally modes specified via the kernel command line (video=...) are
+ * added in addition to what the earlier probes produced
+ * (drm_helper_probe_add_cmdline_mode()). These modes are generated
+ * using the VESA GTF/CVT formulas.
+ *
+ * 3. Modes are moved from the probed_modes list to the modes list. Potential
+ * duplicates are merged together (see drm_mode_connector_list_update()).
+ * After this step the probed_modes list will be empty again.
+ *
+ * 4. Any non-stale mode on the modes list then undergoes validation
+ *
+ * - drm_mode_validate_basic() performs basic sanity checks
+ * - drm_mode_validate_size() filters out modes larger than @maxX and @maxY
+ * (if specified)
+ * - drm_mode_validate_flag() checks the modes againt basic connector
+ * capabilites (interlace_allowed,doublescan_allowed,stereo_allowed)
+ * - the optional connector ->mode_valid() helper can perform driver and/or
+ * hardware specific checks
+ *
+ * 5. Any mode whose status is not OK is pruned from the connector's modes list,

+ * reading system memory it shouldn't (reading it as a texture, or

+ * This validates command lists to ensure that all accesses are within
+ * the bounds of the GEM objects referenced. It explicitly whitelists

+ *
+ * Note that because of the validation that's happening anyway, this

+ * mode feature is disabled with bit GPADC_AUTO_CTRL. AUTO_CONV1_EN = 0
+ * or bit GPADC_AUTO_CTRL. AUTO_CONV0_EN = 0 during a conversion, the

+ * conversion will give 0 as a result. Bit GPADC_STATUS.GPADC_AVAILABLE
+ * will stay at 0 meaning that GPADC is busy. An RT conversion can unlock
+ * the GPADC.
+ *
+ * Workaround(s):
+ * To avoid the lock mechanism, the workaround to follow before any stop
+ * conversion request is:
+ * Force the GPADC state machine to be ON by using the GPADC_CTRL1.
+ * GPADC_FORCE bit = 1
+ * Shutdown the GPADC AUTO conversion using

+ * After 100us, force the GPADC state machine to be OFF by using the
+ * GPADC_CTRL1. GPADC_FORCE bit = 0

+/*
+ * For DMA buffers the storage is sub-divided into so called blocks. Each block
+ * has its own memory buffer. The size of the block is the granularity at which
+ * memory is exchanged between the hardware and the application. Increasing the
+ * basic unit of data exchange from one sample to one block decreases the
+ * management overhead that is associated with each sample. E.g. if we say the
+ * management overhead for one exchange is x and the unit of exchange is one
+ * sample the overhead will be x for each sample. Whereas when using a block
+ * which contains n samples the overhead per sample is reduced to x/n. This
+ * allows to achieve much higher samplerates than what can be sustained with
+ * the one sample approach.
+ *
+ * Blocks are exchanged between the DMA controller and the application via the
+ * means of two queues. The incoming queue and the outgoing queue. Blocks on the
+ * incoming queue are waiting for the DMA controller to pick them up and fill
+ * them with data. Block on the outgoing queue have been filled with data and
+ * are waiting for the application to dequeue them and read the data.
+ *
+ * A block can be in one of the following states:
+ * * Owned by the application. In this state the application can read data from
+ * the block.
+ * * On the incoming list: Blocks on the incoming list are queued up to be
+ * processed by the DMA controller.
+ * * Owned by the DMA controller: The DMA controller is processing the block
+ * and filling it with data.
+ * * On the outgoing list: Blocks on the outgoing list have been successfully
+ * processed by the DMA controller and contain data. They can be dequeued by
+ * the application.
+ * * Dead: A block that is dead has been marked as to be freed. It might still
+ * be owned by either the application or the DMA controller at the moment.
+ * But once they are done processing it instead of going to either the
+ * incoming or outgoing queue the block will be freed.
+ *
+ * In addition to this blocks are reference counted and the memory associated
+ * with both the block structure as well as the storage memory for the block
+ * will be freed when the last reference to the block is dropped. This means a
+ * block must not be accessed without holding a reference.
+ *
+ * The iio_dma_buffer implementation provides a generic infrastructure for
+ * managing the blocks.
+ *
+ * A driver for a specific piece of hardware that has DMA capabilities need to
+ * implement the submit() callback from the iio_dma_buffer_ops structure. This
+ * callback is supposed to initiate the DMA transfer copying data from the
+ * converter to the memory region of the block. Once the DMA transfer has been
+ * completed the driver must call iio_dma_buffer_block_done() for the completed
+ * block.
+ *
+ * Prior to this it must set the bytes_used field of the block contains
+ * the actual number of bytes in the buffer. Typically this will be equal to the
+ * size of the block, but if the DMA hardware has certain alignment requirements
+ * for the transfer length it might choose to use less than the full size. In
+ * either case it is expected that bytes_used is a multiple of the bytes per
+ * datum, i.e. the block must not contain partial samples.
+ *
+ * The driver must call iio_dma_buffer_block_done() for each block it has
+ * received through its submit_block() callback, even if it does not actually
+ * perform a DMA transfer for the block, e.g. because the buffer was disabled
+ * before the block transfer was started. In this case it should set bytes_used
+ * to 0.
+ *
+ * In addition it is recommended that a driver implements the abort() callback.
+ * It will be called when the buffer is disabled and can be used to cancel
+ * pending and stop active transfers.
+ *
+ * The specific driver implementation should use the default callback
+ * implementations provided by this module for the iio_buffer_access_funcs
+ * struct. It may overload some callbacks with custom variants if the hardware
+ * has special requirements that are not handled by the generic functions. If a
+ * driver chooses to overload a callback it has to ensure that the generic
+ * callback is called from within the custom callback.

+ *
+ * On pre-retinas, the LVDS outputs of both GPUs feed into gmux which muxes
+ * either of them to the panel. One of the tricks gmux has up its sleeve is
+ * to lengthen the blanking interval of its output during a switch to
+ * synchronize it with the GPU switched to. This allows for a flicker-free
+ * switch that is imperceptible by the user ({5}[US 8,687,007 B2]).
+ *
+ * On retinas, muxing is no longer done by gmux itself, but by a separate
+ * chip which is controlled by gmux. The chip is triple sourced, it is
+ * either an {6}[NXP CBTL06142], {7}[TI HD3SS212] or {8}[Pericom PI3VDP12412].
+ * The panel is driven with eDP instead of LVDS since the pixel clock
+ * required for retina resolution exceeds LVDS' limits.
+ *
+ * Pre-retinas are able to switch the panel's DDC pins separately.
+ * This is handled by a {9}[TI SN74LV4066A] which is controlled by gmux.
+ * The inactive GPU can thus probe the panel's EDID without switching over
+ * the entire panel. Retinas lack this functionality as the chips used for
+ * eDP muxing are incapable of switching the AUX channel separately (see
+ * the linked data sheets, Pericom would be capable but this is unused).
+ * However the retina panel has the NO_AUX_HANDSHAKE_LINK_TRAINING bit set
+ * in its DPCD, allowing the inactive GPU to skip the AUX handshake and
+ * set up the output with link parameters pre-calibrated by the active GPU.
+ *
+ * The external DP port is only fully switchable on the first two unibody
+ * MacBook Pro generations, MBP5 2008/09 and MBP6 2010. This is done by an
+ * {6}[NXP CBTL06141] which is controlled by gmux. It's the predecessor of the
+ * eDP mux on retinas, the difference being support for 2.7 versus 5.4 Gbit/s.
+ *
+ * The following MacBook Pro generations replaced the external DP port with a
+ * combined DP/Thunderbolt port and lost the ability to switch it between GPUs,
+ * connecting it either to the discrete GPU or the Thunderbolt controller.
+ * Oddly enough, while the full port is no longer switchable, AUX and HPD
+ * are still switchable by way of an {10}[NXP CBTL03062] (on pre-retinas
+ * MBP8 2011 and MBP9 2012) or two {11}[TI TS3DS10224] (on retinas) under the
+ * control of gmux. Since the integrated GPU is missing the main link,
+ * external displays appear to it as phantoms which fail to link-train.
+ *
+ * gmux receives the HPD signal of all display connectors and sends an
+ * interrupt on hotplug. On generations which cannot switch external ports,
+ * the discrete GPU can then be woken to drive the newly connected display.
+ * The ability to switch AUX on these generations could be used to improve
+ * reliability of hotplug detection by having the integrated GPU poll the
+ * ports while the discrete GPU is asleep, but currently we do not make use
+ * of this feature.
+ *
+ * gmux' initial switch state on bootup is user configurable via the EFI
+ * variable `gpu-power-prefs-fa4ce28d-b62f-4c99-9cc3-6815686e30f9` (5th byte,
+ * 1 = IGD, 0 = DIS). Based on this setting, the EFI firmware tells gmux to
+ * switch the panel and the external DP connector and allocates a framebuffer
+ * for the selected GPU.

+ * uniquely identified in the system by the directed edge (local processor ID
+ * to remote processor ID) and a string identifier.
+ *
+ * Each processor is responsible for creating the outgoing SMEM items and each

+ * processor. By using two separate SMEM items that are single-reader and
+ * single-writer, SMP2P does not require any remote locking mechanisms.

+ *
+ * The state bits are structured in entries of 32 bits, each belonging to one
+ * system in the SoC. The entry belonging to the local system is considered

+ *
+ * The subscription matrix consists of N bitmaps per entry, denoting interest
+ * in updates of the entry for each of the N hosts. Upon updating a state bit
+ * each host's subscription bitmap should be queried and the remote system
+ * should be interrupted if they request so.
+ *
+ * The subscription matrix is laid out in entry-major order:
+ * entry0: [host0 ... hostN]
+ * .
+ * .
+ * entryM: [host0 ... hostN]

+ * A third, optional, shared memory region might contain information regarding
+ * the number of entries in the state bitmap as well as number of columns in

+ * Author: H Hartley Sweeten <hsweeten@visionengravers.com>
+ * Updated: Fri, 29 Oct 2015 17:19:35 -0700
+ * Status: untested
+ *
+ * Configuration options: not applicable, uses PCI auto config
+ *
+ * The PCI-1720 has 4 isolated 12-bit analog output channels with multiple
+ * output ranges. It also has a BoardID switch to allow differentiating
+ * multiple boards in the system.
+ *
+ * The analog outputs can operate in two modes, immediate and synchronized.
+ * This driver currently does not support the synchronized output mode.
+ *
+ * Jumpers JP1 to JP4 are used to set the current sink ranges for each
+ * analog output channel. In order to use the current sink ranges, the
+ * unipolar 5V range must be used. The voltage output and sink output for
+ * each channel is available on the connector as separate pins.
+ *
+ * Jumper JP5 controls the "hot" reset state of the analog outputs.
+ * Depending on its setting, the analog outputs will either keep the
+ * last settings and output values or reset to the default state after
+ * a "hot" reset. The default state for all channels is uniploar 5V range
+ * and all the output values are 0V. To allow this feature to work, the
+ * analog outputs are not "reset" when the driver attaches.

---help---
- If you say Y here, you will enable the Unisys visorbus driver.
+ The visorbus driver is a virtualized bus for the Unisys s-Par firmware.
+ Virtualized devices allow Linux guests on a system to share disks and
+ network cards that do not have SR-IOV support, and to be accessed using
+ the partition desktop application. The visorbus driver is required to
+ discover devices on an s-Par guest, and must be present for any other
+ s-Par guest driver to function correctly.

---help---
- If you say Y here, you will enable the Unisys visorinput driver.
+ The Unisys s-Par visorinput driver provides a virtualized system
+ console (keyboard and mouse) that is accessible through the
+ s-Par firmware's user interface. s-Par provides video using the EFI
+ GOP protocol, so If this driver is not present, the Linux guest should
+ still boot with visible output in the partition desktop, but keyboard
+ and mouse interaction will not be available.

+ help
+ VFIO is built on the ability to isolate devices using the IOMMU.
+ Only with an IOMMU can userspace access to DMA capable devices be
+ considered secure. VFIO No-IOMMU mode enables IOMMU groups for
+ devices without IOMMU backing for the purpose of re-using the VFIO
+ infrastructure in a non-secure mode. Use of this mode will result
+ in an unsupportable kernel and will therefore taint the kernel.
+ Device assignment to virtual machines is also not possible with
+ this mode since there is no IOMMU to provide DMA translation.

+
+ With this you can make sure that DISPC FCK is at least
+ n x PCK. Video plane scaling requires higher FCK than
+ normally.
+
+ If this is set to 0, there's no extra constraint on the
+ DISPC FCK. However, the FCK will at minimum be

+ on what platforms this happens.
+
+ This option enables the sleep, and is enabled by default. You can
+ disable the sleep if it doesn't cause problems on your platform.

+ * Page flipping is a synchronization mechanism that replaces the frame

+ * vertical blanking, avoiding tearing (except when requested otherwise
+ * through the DRM_MODE_PAGE_FLIP_ASYNC flag). When an application
+ * requests a page flip the DRM core verifies that the new frame buffer
+ * is large enough to be scanned out by the CRTC in the currently
+ * configured mode and then calls the CRTC ->page_flip() operation with a
+ * pointer to the new frame buffer.
+ *
+ * The driver must wait for any pending rendering to the new framebuffer
+ * to complete before executing the flip. It should also wait for any
+ * pending rendering from other drivers if the underlying buffer is a
+ * shared dma-buf.
+ *
+ * An application can request to be notified when the page flip has
+ * completed. The drm core will supply a struct &drm_event in the event
+ * parameter in this case. This can be handled by the
+ * drm_crtc_send_vblank_event() function, which the driver should call on
+ * the provided event upon completion of the flip. Note that if
+ * the driver supports vblank signalling and timestamping the vblank

+ * - Checking that any hidden shared resources are not oversubscribed.

+ *
+ * - Checking that virtualized resources exported to userspace are not
+ * oversubscribed. For various reasons it can make sense to expose
+ * more planes, crtcs or encoders than which are physically there. One
+ * example is dual-pipe operations (which generally should be hidden
+ * from userspace if when lockstepped in hardware, exposed otherwise),

+ * at least pausing updates for a substantial amount of time) if
+ * userspace has disallowed that in its request.

+ *
+ * See the documentation for struct &drm_atomic_state for how exactly

+ * Asynchronous commits (as indicated with the async parameter) must

+ * errors resulting in -EIO. But even in that case the driver must

+ * The drm core will supply a struct &drm_event in the event

+ * the provided event upon completion of the atomic commit. Note that if
+ * the driver supports vblank signalling and timestamping the vblank
+ * counters and timestamps must agree with the ones returned from page
+ * flip events. With the current vblank helper infrastructure this can
+ * be achieved by holding a vblank reference while the page flip is
+ * pending, acquired through drm_crtc_vblank_get() and released with
+ * drm_crtc_vblank_put(). Drivers are free to implement their own vblank
+ * counter and timestamp tracking though, e.g. if they have accurate
+ * timestamp registers in hardware.
+ *
+ * NOTE:
+ *
+ * Drivers are not allowed to shut down any display pipe successfully
+ * enabled through an atomic commit on their own. Doing so can result in
+ * compositors crashing if a page flip is suddenly rejected because the
+ * pipe is off.
+ *
+ * RETURNS:
+ *
+ * 0 on success or one of the below negative error codes:
+ *
+ * - -EBUSY, if an asynchronous updated is requested and there is
+ * an earlier updated pending. Drivers are allowed to support a queue
+ * of outstanding updates, but currently no driver supports that.
+ * Note that drivers must wait for preceding updates to complete if a
+ * synchronous update is requested, they are not allowed to fail the
+ * commit in that case.
+ *
+ * - -ENOMEM, if the driver failed to allocate memory. Specifically
+ * this can happen when trying to pin framebuffers, which must only
+ * be done when committing the state.
+ *
+ * - -ENOSPC, as a refinement of the more generic -ENOMEM to indicate
+ * that the driver has run out of vram, iommu space or similar GPU
+ * address space needed for framebuffer.
+ *
+ * - -EIO, if the hardware completely died.
+ *
+ * - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted.

+/**
+ * DOC: Media Controller
+ *
+ * The media controller userspace API is documented in DocBook format in
+ * Documentation/DocBook/media/v4l/media-controller.xml. This document focus
+ * on the kernel-side implementation of the media framework.
+ *
+ * * Abstract media device model:
+ *
+ * Discovering a device internal topology, and configuring it at runtime, is one
+ * of the goals of the media framework. To achieve this, hardware devices are
+ * modelled as an oriented graph of building blocks called entities connected
+ * through pads.
+ *
+ * An entity is a basic media hardware building block. It can correspond to
+ * a large variety of logical blocks such as physical hardware devices
+ * (CMOS sensor for instance), logical hardware devices (a building block
+ * in a System-on-Chip image processing pipeline), DMA channels or physical
+ * connectors.
+ *
+ * A pad is a connection endpoint through which an entity can interact with
+ * other entities. Data (not restricted to video) produced by an entity
+ * flows from the entity's output to one or more entity inputs. Pads should
+ * not be confused with physical pins at chip boundaries.
+ *
+ * A link is a point-to-point oriented connection between two pads, either
+ * on the same entity or on different entities. Data flows from a source
+ * pad to a sink pad.
+ *
+ *
+ * * Media device:
+ *
+ * A media device is represented by a struct &media_device instance, defined in
+ * include/media/media-device.h. Allocation of the structure is handled by the
+ * media device driver, usually by embedding the &media_device instance in a
+ * larger driver-specific structure.
+ *
+ * Drivers register media device instances by calling
+ * __media_device_register() via the macro media_device_register()
+ * and unregistered by calling
+ * media_device_unregister().
+ *
+ * * Entities, pads and links:
+ *
+ * - Entities
+ *
+ * Entities are represented by a struct &media_entity instance, defined in
+ * include/media/media-entity.h. The structure is usually embedded into a
+ * higher-level structure, such as a v4l2_subdev or video_device instance,
+ * although drivers can allocate entities directly.
+ *
+ * Drivers initialize entity pads by calling
+ * media_entity_pads_init().
+ *
+ * Drivers register entities with a media device by calling
+ * media_device_register_entity()
+ * and unregistred by calling
+ * media_device_unregister_entity().
+ *
+ * - Interfaces
+ *
+ * Interfaces are represented by a struct &media_interface instance, defined in
+ * include/media/media-entity.h. Currently, only one type of interface is
+ * defined: a device node. Such interfaces are represented by a struct
+ * &media_intf_devnode.
+ *
+ * Drivers initialize and create device node interfaces by calling
+ * media_devnode_create()
+ * and remove them by calling:
+ * media_devnode_remove().
+ *
+ * - Pads
+ *
+ * Pads are represented by a struct &media_pad instance, defined in
+ * include/media/media-entity.h. Each entity stores its pads in a pads array
+ * managed by the entity driver. Drivers usually embed the array in a
+ * driver-specific structure.
+ *
+ * Pads are identified by their entity and their 0-based index in the pads
+ * array.
+ * Both information are stored in the &media_pad structure, making the
+ * &media_pad pointer the canonical way to store and pass link references.
+ *
+ * Pads have flags that describe the pad capabilities and state.
+ *
+ * %MEDIA_PAD_FL_SINK indicates that the pad supports sinking data.
+ * %MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data.
+ *
+ * NOTE: One and only one of %MEDIA_PAD_FL_SINK and %MEDIA_PAD_FL_SOURCE must
+ * be set for each pad.
+ *
+ * - Links
+ *
+ * Links are represented by a struct &media_link instance, defined in
+ * include/media/media-entity.h. There are two types of links:
+ *
+ * 1. pad to pad links:
+ *
+ * Associate two entities via their PADs. Each entity has a list that points
+ * to all links originating at or targeting any of its pads.
+ * A given link is thus stored twice, once in the source entity and once in
+ * the target entity.
+ *
+ * Drivers create pad to pad links by calling:
+ * media_create_pad_link() and remove with media_entity_remove_links().
+ *
+ * 2. interface to entity links:
+ *
+ * Associate one interface to a Link.
+ *
+ * Drivers create interface to entity links by calling:
+ * media_create_intf_link() and remove with media_remove_intf_links().
+ *
+ * NOTE:
+ *
+ * Links can only be created after having both ends already created.
+ *
+ * Links have flags that describe the link capabilities and state. The
+ * valid values are described at media_create_pad_link() and
+ * media_create_intf_link().
+ *
+ * Graph traversal:
+ *
+ * The media framework provides APIs to iterate over entities in a graph.
+ *
+ * To iterate over all entities belonging to a media device, drivers can use
+ * the media_device_for_each_entity macro, defined in
+ * include/media/media-device.h.
+ *
+ * struct media_entity *entity;
+ *
+ * media_device_for_each_entity(entity, mdev) {
+ * // entity will point to each entity in turn
+ * ...
+ * }
+ *
+ * Drivers might also need to iterate over all entities in a graph that can be
+ * reached only through enabled links starting at a given entity. The media
+ * framework provides a depth-first graph traversal API for that purpose.
+ *
+ * Note that graphs with cycles (whether directed or undirected) are *NOT*
+ * supported by the graph traversal API. To prevent infinite loops, the graph
+ * traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH,
+ * currently defined as 16.
+ *
+ * Drivers initiate a graph traversal by calling
+ * media_entity_graph_walk_start()
+ *
+ * The graph structure, provided by the caller, is initialized to start graph
+ * traversal at the given entity.
+ *
+ * Drivers can then retrieve the next entity by calling
+ * media_entity_graph_walk_next()
+ *
+ * When the graph traversal is complete the function will return NULL.
+ *
+ * Graph traversal can be interrupted at any moment. No cleanup function call
+ * is required and the graph structure can be freed normally.
+ *
+ * Helper functions can be used to find a link between two given pads, or a pad
+ * connected to another pad through an enabled link
+ * media_entity_find_link() and media_entity_remote_pad()
+ *
+ * Use count and power handling:
+ *
+ * Due to the wide differences between drivers regarding power management
+ * needs, the media controller does not implement power management. However,
+ * the &media_entity structure includes a use_count field that media drivers
+ * can use to track the number of users of every entity for power management
+ * needs.
+ *
+ * The &media_entity.@use_count field is owned by media drivers and must not be
+ * touched by entity drivers. Access to the field must be protected by the
+ * &media_device.@graph_mutex lock.
+ *
+ * Links setup:
+ *
+ * Link properties can be modified at runtime by calling
+ * media_entity_setup_link()
+ *
+ * Pipelines and media streams:
+ *
+ * When starting streaming, drivers must notify all entities in the pipeline to
+ * prevent link states from being modified during streaming by calling
+ * media_entity_pipeline_start().
+ *
+ * The function will mark all entities connected to the given entity through
+ * enabled links, either directly or indirectly, as streaming.
+ *
+ * The &media_pipeline instance pointed to by the pipe argument will be stored
+ * in every entity in the pipeline. Drivers should embed the &media_pipeline
+ * structure in higher-level pipeline structures and can then access the
+ * pipeline through the &media_entity pipe field.
+ *
+ * Calls to media_entity_pipeline_start() can be nested. The pipeline pointer
+ * must be identical for all nested calls to the function.
+ *
+ * media_entity_pipeline_start() may return an error. In that case, it will
+ * clean up any of the changes it did by itself.
+ *
+ * When stopping the stream, drivers must notify the entities with
+ * media_entity_pipeline_stop().
+ *
+ * If multiple calls to media_entity_pipeline_start() have been made the same
+ * number of media_entity_pipeline_stop() calls are required to stop streaming.
+ * The &media_entity pipe field is reset to NULL on the last nested stop call.
+ *
+ * Link configuration will fail with -%EBUSY by default if either end of the
+ * link is a streaming entity. Links that can be modified while streaming must
+ * be marked with the %MEDIA_LNK_FL_DYNAMIC flag.
+ *
+ * If other operations need to be disallowed on streaming entities (such as
+ * changing entities configuration parameters) drivers can explicitly check the
+ * media_entity stream_count field to find out if an entity is streaming. This
+ * operation must be done with the media_device graph_mutex held.
+ *
+ * Link validation:
+ *
+ * Link validation is performed by media_entity_pipeline_start() for any
+ * entity which has sink pads in the pipeline. The
+ * &media_entity.@link_validate() callback is used for that purpose. In
+ * @link_validate() callback, entity driver should check that the properties of
+ * the source pad of the connected entity and its own sink pad match. It is up
+ * to the type of the entity (and in the end, the properties of the hardware)
+ * what matching actually means.
+ *
+ * Subsystems should facilitate link validation by providing subsystem specific
+ * helper functions to provide easy access for commonly needed information, and
+ * in the end provide a way to use driver-specific callbacks.

+ * engine.
+ *
+ * Drivers typically use GPU BOs to store batchbuffers / command lists and
+ * their associated state. However, because the VC4 lacks an MMU, we have to
+ * do validation of memory accesses by the GPU commands. If we were to store
+ * our commands in BOs, we'd need to do uncached readback from them to do the
+ * validation process, which is too expensive. Instead, userspace accumulates
+ * commands and associated state in plain memory, then the kernel copies the
+ * data to its own address space, and then validates and stores it in a GPU
+ * BO.

+# This test runs on Intel x86 based hardware which support the intel_pstate
+# driver. The test checks the frequency settings from the maximum turbo
+# state to the minimum supported frequency, in decrements of 100MHz. The
+# test runs the aperf.c program to put load on each processor.
+#
+# The results are displayed in a table which indicate the "Target" state,
+# or the requested frequency in MHz, the Actual frequency, as read from
+# /proc/cpuinfo, the difference between the Target and Actual frequencies,
+# and the value of MSR 0x199 (MSR_IA32_PERF_CTL) which indicates what
+# pstate the cpu is in, and the value of
+# /sys/devices/system/cpu/intel_pstate/max_perf_pct X maximum turbo state
+#
+# Notes: In some cases several frequency values may be placed in the
+# /tmp/result.X files. This is done on purpose in order to catch cases
+# where the pstate driver may not be working at all. There is the case
+# where, for example, several "similar" frequencies are in the file:
+#
+#
+#/tmp/result.3100:1:cpu MHz : 2899.980
+#/tmp/result.3100:2:cpu MHz : 2900.000
+#/tmp/result.3100:3:msr 0x199: 0x1e00
+#/tmp/result.3100:4:max_perf_pct 94
+#
+# and the test will error out in those cases. The result.X file can be checked
+# for consistency and modified to remove the extra MHz values. The result.X
+# files can be re-evaluated by setting EVALUATE_ONLY to 1 below.
