+ The node name must be "cpus".
+
+ A cpus node must define the following properties:

+ # On uniprocessor ARM architectures previous to v7
+ value must be 1, to enable a simple enumeration
+ scheme for processors that do not have a HW CPU
+ identification register.

+ that corresponds to the MPIDR_EL1 register size.
+ If MPIDR_EL1[63:32] value is equal to 0 on all CPUs

+ARM topology binding description
+===========================================
+
+===========================================
+1 - Introduction
+===========================================
+
+In an ARM system, the hierarchy of CPUs is defined through three entities that
+are used to describe the layout of physical CPUs in the system:
+
+- cluster
+- core
+- thread
+
+The cpu nodes (bindings defined in [1]) represent the devices that
+correspond to physical CPUs and are to be mapped to the hierarchy levels.
+
+The bottom hierarchy level sits at core or thread level depending on whether
+symmetric multi-threading (SMT) is supported or not.
+
+For instance in a system where CPUs support SMT, "cpu" nodes represent all
+threads existing in the system and map to the hierarchy level "thread" above.
+In systems where SMT is not supported "cpu" nodes represent all cores present
+in the system and map to the hierarchy level "core" above.
+
+ARM topology bindings allow one to associate cpu nodes with hierarchical groups
+corresponding to the system hierarchy; syntactically they are defined as device
+tree nodes.
+
+The remainder of this document provides the topology bindings for ARM, based
+on the ePAPR standard, available from:
+
+http://www.power.org/documentation/epapr-version-1-1/
+
+If not stated otherwise, whenever a reference to a cpu node phandle is made its
+value must point to a cpu node compliant with the cpu node bindings as
+documented in [1].
+A topology description containing phandles to cpu nodes that are not compliant
+with bindings standardized in [1] is therefore considered invalid.
+
+===========================================
+2 - cpu-map node
+===========================================
+
+The ARM CPU topology is defined within the cpu-map node, which is a direct
+child of the cpus node and provides a container where the actual topology
+nodes are listed.
+
+- cpu-map node
+
+ Usage: Optional - On ARM SMP systems provide CPUs topology to the OS.
+ ARM uniprocessor systems do not require a topology
+ description and therefore should not define a
+ cpu-map node.
+
+ Description: The cpu-map node is just a container node where its
+ subnodes describe the CPU topology.
+
+ Node name must be "cpu-map".
+
+ The cpu-map node's parent node must be the cpus node.
+
+ The cpu-map node's child nodes can be:
+
+ - one or more cluster nodes
+
+ Any other configuration is considered invalid.
+
+The cpu-map node can only contain three types of child nodes:
+
+- cluster node
+- core node
+- thread node
+
+whose bindings are described in paragraph 3.
+
+The nodes describing the CPU topology (cluster/core/thread) can only be
+defined within the cpu-map node.
+Any other configuration is consider invalid and therefore must be ignored.
+
+===========================================
+2.1 - cpu-map child nodes naming convention
+===========================================
+
+cpu-map child nodes must follow a naming convention where the node name
+must be "clusterN", "coreN", "threadN" depending on the node type (ie
+cluster/core/thread) (where N = {0, 1, ...} is the node number; nodes which
+are siblings within a single common parent node must be given a unique and
+sequential N value, starting from 0).
+cpu-map child nodes which do not share a common parent node can have the same
+name (ie same number N as other cpu-map child nodes at different device tree
+levels) since name uniqueness will be guaranteed by the device tree hierarchy.
+
+===========================================
+3 - cluster/core/thread node bindings
+===========================================
+
+Bindings for cluster/cpu/thread nodes are defined as follows:
+
+- cluster node
+
+ Description: must be declared within a cpu-map node, one node
+ per cluster. A system can contain several layers of
+ clustering and cluster nodes can be contained in parent
+ cluster nodes.
+
+ The cluster node name must be "clusterN" as described in 2.1 above.
+ A cluster node can not be a leaf node.
+
+ A cluster node's child nodes must be:
+
+ - one or more cluster nodes; or
+ - one or more core nodes
+
+ Any other configuration is considered invalid.
+
+- core node
+
+ Description: must be declared in a cluster node, one node per core in
+ the cluster. If the system does not support SMT, core
+ nodes are leaf nodes, otherwise they become containers of
+ thread nodes.
+
+ The core node name must be "coreN" as described in 2.1 above.
+
+ A core node must be a leaf node if SMT is not supported.
+
+ Properties for core nodes that are leaf nodes:
+
+ - cpu
+ Usage: required
+ Value type: <phandle>
+ Definition: a phandle to the cpu node that corresponds to the
+ core node.
+
+ If a core node is not a leaf node (CPUs supporting SMT) a core node's
+ child nodes can be:
+
+ - one or more thread nodes
+
+ Any other configuration is considered invalid.
+
+- thread node
+
+ Description: must be declared in a core node, one node per thread
+ in the core if the system supports SMT. Thread nodes are
+ always leaf nodes in the device tree.
+
+ The thread node name must be "threadN" as described in 2.1 above.
+
+ A thread node must be a leaf node.
+
+ A thread node must contain the following property:
+
+ - cpu
+ Usage: required
+ Value type: <phandle>
+ Definition: a phandle to the cpu node that corresponds to
+ the thread node.

+Broadcom Kona Family GPIO
+=========================
+
+This GPIO driver is used in the following Broadcom SoCs:
+ BCM11130, BCM11140, BCM11351, BCM28145, BCM28155
+
+The Broadcom GPIO Controller IP can be configured prior to synthesis to
+support up to 8 banks of 32 GPIOs where each bank has its own IRQ. The
+GPIO controller only supports edge, not level, triggering of interrupts.
+
+Required properties
+-------------------
+
+- compatible: "brcm,bcm11351-gpio", "brcm,kona-gpio"
+- reg: Physical base address and length of the controller's registers.
+- interrupts: The interrupt outputs from the controller. There is one GPIO
+ interrupt per GPIO bank. The number of interrupts listed depends on the
+ number of GPIO banks on the SoC. The interrupts must be ordered by bank,
+ starting with bank 0. There is always a 1:1 mapping between banks and
+ IRQs.
+- #gpio-cells: Should be <2>. The first cell is the pin number, the second
+ cell is used to specify optional parameters:
+ - bit 0 specifies polarity (0 for normal, 1 for inverted)
+ See also "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
+- #interrupt-cells: Should be <2>. The first cell is the GPIO number. The
+ second cell is used to specify flags. The following subset of flags is
+ supported:
+ - trigger type (bits[1:0]):
+ 1 = low-to-high edge triggered.
+ 2 = high-to-low edge triggered.
+ 3 = low-to-high or high-to-low edge triggered
+ Valid values are 1, 2, 3
+ See also .../devicetree/bindings/interrupt-controller/interrupts.txt.
+- gpio-controller: Marks the device node as a GPIO controller.
+- interrupt-controller: Marks the device node as an interrupt controller.
+

+* PCF857x-compatible I/O expanders
+
+The PCF857x-compatible chips have "quasi-bidirectional" I/O lines that can be
+driven high by a pull-up current source or driven low to ground. This combines
+the direction and output level into a single bit per line, which can't be read
+back. We can't actually know at initialization time whether a line is configured
+(a) as output and driving the signal low/high, or (b) as input and reporting a
+low/high value, without knowing the last value written since the chip came out
+of reset (if any). The only reliable solution for setting up line direction is
+thus to do it explicitly.
+
+Required Properties:
+
+ - compatible: should be one of the following.
+ - "maxim,max7328": For the Maxim MAX7378
+ - "maxim,max7329": For the Maxim MAX7329
+ - "nxp,pca8574": For the NXP PCA8574
+ - "nxp,pca8575": For the NXP PCA8575
+ - "nxp,pca9670": For the NXP PCA9670

+ - "nxp,pcf8574a": For the NXP PCF8574A
+ - "nxp,pcf8575": For the NXP PCF8575
+ - "ti,tca9554": For the TI TCA9554
+
+ - reg: I2C slave address.
+
+ - gpio-controller: Marks the device node as a gpio controller.
+ - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
+ cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
+ GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
+
+Optional Properties:
+
+ - lines-initial-states: Bitmask that specifies the initial state of each
+ line. When a bit is set to zero, the corresponding line will be initialized to
+ the input (pulled-up) state. When the bit is set to one, the line will be
+ initialized the the low-level output state. If the property is not specified
+ all lines will be initialized to the input state.
+
+ The I/O expander can detect input state changes, and thus optionally act as
+ an interrupt controller. When the expander interrupt line is connected all the
+ following properties must be set. For more information please see the
+ interrupt controller device tree bindings documentation available at
+ Documentation/devicetree/bindings/interrupt-controller/interrupts.txt.

-*** Memory binding ***
-
-The /memory node provides basic information about the address and size
-of the physical memory. This node is usually filled or updated by the
-bootloader, depending on the actual memory configuration of the given
-hardware.
-
-The memory layout is described by the following node:
-
-/ {
- #address-cells = <(n)>;
- #size-cells = <(m)>;
- memory {
- device_type = "memory";
- reg = <(baseaddr1) (size1)
- (baseaddr2) (size2)
- ...
- (baseaddrN) (sizeN)>;
- };
- ...
-};
-
-A memory node follows the typical device tree rules for "reg" property:
-n: number of cells used to store base address value
-m: number of cells used to store size value
-baseaddrX: defines a base address of the defined memory bank
-sizeX: the size of the defined memory bank
-
-
-More than one memory bank can be defined.
-
-
-*** Reserved memory regions ***
-
-In /memory/reserved-memory node one can create child nodes describing
-particular reserved (excluded from normal use) memory regions. Such
-memory regions are usually designed for the special usage by various
-device drivers. A good example are contiguous memory allocations or
-memory sharing with other operating system on the same hardware board.
-Those special memory regions might depend on the board configuration and
-devices used on the target system.
-
-Parameters for each memory region can be encoded into the device tree
-with the following convention:
-
-[(label):] (name) {
- compatible = "linux,contiguous-memory-region", "reserved-memory-region";
- reg = <(address) (size)>;
- (linux,default-contiguous-region);
-};
-
-compatible: one or more of:
- - "linux,contiguous-memory-region" - enables binding of this
- region to Contiguous Memory Allocator (special region for
- contiguous memory allocations, shared with movable system
- memory, Linux kernel-specific).
- - "reserved-memory-region" - compatibility is defined, given
- region is assigned for exclusive usage for by the respective
- devices.
-
-reg: standard property defining the base address and size of
- the memory region
-
-linux,default-contiguous-region: property indicating that the region
- is the default region for all contiguous memory
- allocations, Linux specific (optional)
-
-It is optional to specify the base address, so if one wants to use
-autoconfiguration of the base address, '0' can be specified as a base
-address in the 'reg' property.
-
-The /memory/reserved-memory node must contain the same #address-cells
-and #size-cells value as the root node.
-
-
-*** Device node's properties ***
-
-Once regions in the /memory/reserved-memory node have been defined, they
-may be referenced by other device nodes. Bindings that wish to reference
-memory regions should explicitly document their use of the following
-property:
-
-memory-region = <&phandle_to_defined_region>;
-
-This property indicates that the device driver should use the memory
-region pointed by the given phandle.
-
-
-*** Example ***
-
-This example defines a memory consisting of 4 memory banks. 3 contiguous
-regions are defined for Linux kernel, one default of all device drivers
-(named contig_mem, placed at 0x72000000, 64MiB), one dedicated to the
-framebuffer device (labelled display_mem, placed at 0x78000000, 8MiB)
-and one for multimedia processing (labelled multimedia_mem, placed at
-0x77000000, 64MiB). 'display_mem' region is then assigned to fb@12300000
-device for DMA memory allocations (Linux kernel drivers will use CMA is
-available or dma-exclusive usage otherwise). 'multimedia_mem' is
-assigned to scaler@12500000 and codec@12600000 devices for contiguous
-memory allocations when CMA driver is enabled.
-
-The reason for creating a separate region for framebuffer device is to
-match the framebuffer base address to the one configured by bootloader,
-so once Linux kernel drivers starts no glitches on the displayed boot
-logo appears. Scaller and codec drivers should share the memory
-allocations.

+
+PHY device node
+===============
+
+Required Properties:
+#phy-cells: Number of cells in a PHY specifier; The meaning of all those
+ cells is defined by the binding for the phy node. The PHY
+ provider can use the values in cells to find the appropriate
+ PHY.
+
+For example:
+
+phys: phy {
+ compatible = "xxx";
+ reg = <...>;
+ .
+ .
+ #phy-cells = <1>;
+ .
+ .
+};
+
+That node describes an IP block (PHY provider) that implements 2 different PHYs.
+In order to differentiate between these 2 PHYs, an additonal specifier should be
+given while trying to get a reference to it.
+
+PHY user node
+=============
+
+Required Properties:
+phys : the phandle for the PHY device (used by the PHY subsystem)
+phy-names : the names of the PHY corresponding to the PHYs present in the
+ *phys* phandle
+
+Example 1:
+usb1: usb_otg_ss@xxx {
+ compatible = "xxx";
+ reg = <xxx>;
+ .
+ .
+ phys = <&usb2_phy>, <&usb3_phy>;
+ phy-names = "usb2phy", "usb3phy";
+ .
+ .
+};
+
+This node represents a controller that uses two PHYs, one for usb2 and one for
+usb3.
+
+Example 2:
+usb2: usb_otg_ss@xxx {
+ compatible = "xxx";
+ reg = <xxx>;
+ .
+ .
+ phys = <&phys 1>;
+ phy-names = "usbphy";
+ .
+ .
+};
+
+This node represents a controller that uses one of the PHYs of the PHY provider
+device defined previously. Note that the phy handle has an additional specifier
+"1" to differentiate between the two PHYs.

+-------------------
+
+- compatible: should be "abilis,tb10x-iomux";
+- reg: should contain the physical address and size of the pin controller's
+ register range.
+
+
+Function definitions
+--------------------
+
+Functions are defined (and referenced) by sub-nodes of the pin controller.
+Every sub-node defines exactly one function (implying a set of pins).
+Every function is associated to one named pin group inside the pin controller
+driver and these names are used to associate pin group predefinitions to pin
+controller sub-nodes.
+
+Required function definition subnode properties:
+ - abilis,function: should be set to the name of the function's pin group.
+
+The following pin groups are available:
+ - GPIO ports: gpioa, gpiob, gpioc, gpiod, gpioe, gpiof, gpiog,
+ gpioh, gpioi, gpioj, gpiok, gpiol, gpiom, gpion
+ - Serial TS input ports: mis0, mis1, mis2, mis3, mis4, mis5, mis6, mis7
+ - Parallel TS input ports: mip1, mip3, mip5, mip7
+ - Serial TS output ports: mos0, mos1, mos2, mos3
+ - Parallel TS output port: mop
+ - CI+ port: ciplus
+ - CableCard (Mcard) port: mcard
+ - Smart card ports: stc0, stc1
+ - UART ports: uart0, uart1
+ - SPI ports: spi1, spi3
+ - JTAG: jtag
+
+All other ports of the chip are not multiplexed and thus not managed by this
+driver.
+
+
+GPIO ranges definition
+----------------------
+
+The named pin groups of GPIO ports can be used to define GPIO ranges as
+explained in Documentation/devicetree/bindings/gpio/gpio.txt.
+
+
+Example

+
+Required properties:
+- compatible: "fsl,imx27-iomuxc"
+
+The iomuxc driver node should define subnodes containing of pinctrl configuration subnodes.
+
+Required properties for pin configuration node:
+- fsl,pins: three integers array, represents a group of pins mux and config
+ setting. The format is fsl,pins = <PIN MUX_ID CONFIG>.
+
+ PIN is an integer between 0 and 0xbf. imx27 has 6 ports with 32 configurable
+ configurable pins each. PIN is PORT * 32 + PORT_PIN, PORT_PIN is the pin
+ number on the specific port (between 0 and 31).
+
+ MUX_ID is
+ function + (direction << 2) + (gpio_oconf << 4) + (gpio_iconfa << 8) + (gpio_iconfb << 10)
+
+ function value is used to select the pin function.
+ Possible values:
+ 0 - Primary function
+ 1 - Alternate function
+ 2 - GPIO
+ Registers: GIUS (GPIO In Use), GPR (General Purpose Register)
+
+ direction defines the data direction of the pin.
+ Possible values:
+ 0 - Input
+ 1 - Output
+ Register: DDIR
+
+ gpio_oconf configures the gpio submodule output signal. This does not
+ have any effect unless GPIO function is selected. A/B/C_IN are output
+ signals of function blocks A,B and C. Specific function blocks are
+ described in the reference manual.
+ Possible values:
+ 0 - A_IN
+ 1 - B_IN
+ 2 - C_IN
+ 3 - Data Register
+ Registers: OCR1, OCR2
+
+ gpio_iconfa/b configures the gpio submodule input to functionblocks A and
+ B. GPIO function should be selected if this is configured.
+ Possible values:
+ 0 - GPIO_IN
+ 1 - Interrupt Status Register
+ 2 - Pulldown
+ 3 - Pullup
+ Registers ICONFA1, ICONFA2, ICONFB1 and ICONFB2
+
+ CONFIG can be 0 or 1, meaning Pullup disable/enable.
+
+
+
+Example:
+
+iomuxc: iomuxc@10015000 {
+ compatible = "fsl,imx27-iomuxc";
+ reg = <0x10015000 0x600>;

+ 0x8f 0x000 0x0 /* UART1_RTS__UART1_RTS */
+ >;
+ };
+
+ ...

+
+
+For convenience there are macros defined in imx27-pinfunc.h which provide PIN
+and MUX_ID. They are structured as MX27_PAD_<Pad name>__<Signal name>. The names

+COOKIE ENABLEMENT
+=================
+
+Cookies exist in one of two states: enabled and disabled. If a cookie is
+disabled, it ignores all attempts to acquire child cookies; check, update or
+invalidate its state; allocate, read or write backing pages - though it is
+still possible to uncache pages and relinquish the cookie.
+
+The initial enablement state is set by fscache_acquire_cookie(), but the cookie
+can be enabled or disabled later. To disable a cookie, call:
+
+ void fscache_disable_cookie(struct fscache_cookie *cookie,
+ bool invalidate);
+
+If the cookie is not already disabled, this locks the cookie against other
+enable and disable ops, marks the cookie as being disabled, discards or
+invalidates any backing objects and waits for cessation of activity on any
+associated object before unlocking the cookie.
+
+All possible failures are handled internally. The caller should consider
+calling fscache_uncache_all_inode_pages() afterwards to make sure all page
+markings are cleared up.
+
+Cookies can be enabled or reenabled with:
+
+ void fscache_enable_cookie(struct fscache_cookie *cookie,
+ bool (*can_enable)(void *data),
+ void *data)
+
+If the cookie is not already enabled, this locks the cookie against other
+enable and disable ops, invokes can_enable() and, if the cookie is not an index
+cookie, will begin the procedure of acquiring backing objects.
+
+The optional can_enable() function is passed the data argument and returns a
+ruling as to whether or not enablement should actually be permitted to begin.

+An Intel MIC X100 device is a PCIe form factor add-in coprocessor
+card based on the Intel Many Integrated Core (MIC) architecture
+that runs a Linux OS. It is a PCIe endpoint in a platform and therefore
+implements the three required standard address spaces i.e. configuration,
+memory and I/O. The host OS loads a device driver as is typical for
+PCIe devices. The card itself runs a bootstrap after reset that
+transfers control to the card OS downloaded from the host driver. The
+host driver supports OSPM suspend and resume operations. It shuts down
+the card during suspend and reboots the card OS during resume.
+The card OS as shipped by Intel is a Linux kernel with modifications
+for the X100 devices.
+
+Since it is a PCIe card, it does not have the ability to host hardware
+devices for networking, storage and console. We provide these devices
+on X100 coprocessors thus enabling a self-bootable equivalent environment
+for applications. A key benefit of our solution is that it leverages
+the standard virtio framework for network, disk and console devices,
+though in our case the virtio framework is used across a PCIe bus.
+
+Here is a block diagram of the various components described above. The
+virtio backends are situated on the host rather than the card given better
+single threaded performance for the host compared to MIC, the ability of
+the host to initiate DMA's to/from the card using the MIC DMA engine and
+the fact that the virtio block storage backend can only be on the host.

+ PHY SUBSYSTEM
+ Kishon Vijay Abraham I <kishon@ti.com>
+
+This document explains the Generic PHY Framework along with the APIs provided,
+and how-to-use.
+
+1. Introduction
+
+*PHY* is the abbreviation for physical layer. It is used to connect a device
+to the physical medium e.g., the USB controller has a PHY to provide functions
+such as serialization, de-serialization, encoding, decoding and is responsible
+for obtaining the required data transmission rate. Note that some USB
+controllers have PHY functionality embedded into it and others use an external
+PHY. Other peripherals that use PHY include Wireless LAN, Ethernet,
+SATA etc.
+
+The intention of creating this framework is to bring the PHY drivers spread
+all over the Linux kernel to drivers/phy to increase code re-use and for
+better code maintainability.
+
+This framework will be of use only to devices that use external PHY (PHY
+functionality is not embedded within the controller).
+
+2. Registering/Unregistering the PHY provider
+
+PHY provider refers to an entity that implements one or more PHY instances.
+For the simple case where the PHY provider implements only a single instance of
+the PHY, the framework provides its own implementation of of_xlate in
+of_phy_simple_xlate. If the PHY provider implements multiple instances, it
+should provide its own implementation of of_xlate. of_xlate is used only for
+dt boot case.
+
+#define of_phy_provider_register(dev, xlate) \
+ __of_phy_provider_register((dev), THIS_MODULE, (xlate))
+
+#define devm_of_phy_provider_register(dev, xlate) \
+ __devm_of_phy_provider_register((dev), THIS_MODULE, (xlate))
+
+of_phy_provider_register and devm_of_phy_provider_register macros can be used to
+register the phy_provider and it takes device and of_xlate as
+arguments. For the dt boot case, all PHY providers should use one of the above
+2 macros to register the PHY provider.
+
+void devm_of_phy_provider_unregister(struct device *dev,
+ struct phy_provider *phy_provider);
+void of_phy_provider_unregister(struct phy_provider *phy_provider);
+
+devm_of_phy_provider_unregister and of_phy_provider_unregister can be used to
+unregister the PHY.
+
+3. Creating the PHY
+
+The PHY driver should create the PHY in order for other peripheral controllers
+to make use of it. The PHY framework provides 2 APIs to create the PHY.
+
+struct phy *phy_create(struct device *dev, const struct phy_ops *ops,
+ struct phy_init_data *init_data);
+struct phy *devm_phy_create(struct device *dev, const struct phy_ops *ops,
+ struct phy_init_data *init_data);
+
+The PHY drivers can use one of the above 2 APIs to create the PHY by passing
+the device pointer, phy ops and init_data.
+phy_ops is a set of function pointers for performing PHY operations such as
+init, exit, power_on and power_off. *init_data* is mandatory to get a reference
+to the PHY in the case of non-dt boot. See section *Board File Initialization*
+on how init_data should be used.
+
+Inorder to dereference the private data (in phy_ops), the phy provider driver
+can use phy_set_drvdata() after creating the PHY and use phy_get_drvdata() in
+phy_ops to get back the private data.
+
+4. Getting a reference to the PHY
+
+Before the controller can make use of the PHY, it has to get a reference to
+it. This framework provides the following APIs to get a reference to the PHY.
+
+struct phy *phy_get(struct device *dev, const char *string);
+struct phy *devm_phy_get(struct device *dev, const char *string);
+
+phy_get and devm_phy_get can be used to get the PHY. In the case of dt boot,
+the string arguments should contain the phy name as given in the dt data and
+in the case of non-dt boot, it should contain the label of the PHY.
+The only difference between the two APIs is that devm_phy_get associates the
+device with the PHY using devres on successful PHY get. On driver detach,
+release function is invoked on the the devres data and devres data is freed.
+
+5. Releasing a reference to the PHY
+
+When the controller no longer needs the PHY, it has to release the reference
+to the PHY it has obtained using the APIs mentioned in the above section. The
+PHY framework provides 2 APIs to release a reference to the PHY.
+
+void phy_put(struct phy *phy);
+void devm_phy_put(struct device *dev, struct phy *phy);
+
+Both these APIs are used to release a reference to the PHY and devm_phy_put
+destroys the devres associated with this PHY.
+
+6. Destroying the PHY
+
+When the driver that created the PHY is unloaded, it should destroy the PHY it
+created using one of the following 2 APIs.
+
+void phy_destroy(struct phy *phy);
+void devm_phy_destroy(struct device *dev, struct phy *phy);
+
+Both these APIs destroy the PHY and devm_phy_destroy destroys the devres
+associated with this PHY.
+
+7. PM Runtime
+
+This subsystem is pm runtime enabled. So while creating the PHY,
+pm_runtime_enable of the phy device created by this subsystem is called and
+while destroying the PHY, pm_runtime_disable is called. Note that the phy
+device created by this subsystem will be a child of the device that calls
+phy_create (PHY provider device).
+
+So pm_runtime_get_sync of the phy_device created by this subsystem will invoke
+pm_runtime_get_sync of PHY provider device because of parent-child relationship.
+It should also be noted that phy_power_on and phy_power_off performs
+phy_pm_runtime_get_sync and phy_pm_runtime_put respectively.
+There are exported APIs like phy_pm_runtime_get, phy_pm_runtime_get_sync,
+phy_pm_runtime_put, phy_pm_runtime_put_sync, phy_pm_runtime_allow and
+phy_pm_runtime_forbid for performing PM operations.
+
+8. Board File Initialization
+
+Certain board file initialization is necessary in order to get a reference
+to the PHY in the case of non-dt boot.
+Say we have a single device that implements 3 PHYs that of USB, SATA and PCIe,
+then in the board file the following initialization should be done.
+
+struct phy_consumer consumers[] = {
+ PHY_CONSUMER("dwc3.0", "usb"),
+ PHY_CONSUMER("pcie.0", "pcie"),
+ PHY_CONSUMER("sata.0", "sata"),
+};
+PHY_CONSUMER takes 2 parameters, first is the device name of the controller
+(PHY consumer) and second is the port name.
+
+struct phy_init_data init_data = {
+ .consumers = consumers,
+ .num_consumers = ARRAY_SIZE(consumers),
+};
+
+static const struct platform_device pipe3_phy_dev = {
+ .name = "pipe3-phy",
+ .id = -1,
+ .dev = {
+ .platform_data = {
+ .init_data = &init_data,
+ },
+ },
+};
+
+then, while doing phy_create, the PHY driver should pass this init_data
+ phy_create(dev, ops, pdata->init_data);
+
+and the controller driver (phy consumer) should pass the port name along with
+the device to get a reference to the PHY
+ phy_get(dev, "pcie");
+
+9. DeviceTree Binding
+
+The documentation for PHY dt binding can be found @

+PPS with USB to serial devices
+------------------------------
+
+It is possible to grab the PPS from an USB to serial device. However,
+you should take into account the latencies and jitter introduced by
+the USB stack. Users has reported clock instability around +-1ms when
+synchronized with PPS through USB. This isn't suited for time server
+synchronization.
+
+If your device doesn't report PPS, you can check that the feature is

+Dynamic PCM
+===========
+
+1. Description
+==============
+
+Dynamic PCM allows an ALSA PCM device to digitally route its PCM audio to
+various digital endpoints during the PCM stream runtime. e.g. PCM0 can route
+digital audio to I2S DAI0, I2S DAI1 or PDM DAI2. This is useful for on SoC DSP
+drivers that expose several ALSA PCMs and can route to multiple DAIs.
+
+The DPCM runtime routing is determined by the ALSA mixer settings in the same
+way as the analog signal is routed in an ASoC codec driver. DPCM uses a DAPM
+graph representing the DSP internal audio paths and uses the mixer settings to
+determine the patch used by each ALSA PCM.
+
+DPCM re-uses all the existing component codec, platform and DAI drivers without
+any modifications.
+
+
+Phone Audio System with SoC based DSP
+-------------------------------------
+
+Consider the following phone audio subsystem. This will be used in this
+document for all examples :-
+
+| Front End PCMs | SoC DSP | Back End DAIs | Audio devices |
+
+ *************
+PCM0 <------------> * * <----DAI0-----> Codec Headset
+ * *
+PCM1 <------------> * * <----DAI1-----> Codec Speakers
+ * DSP *
+PCM2 <------------> * * <----DAI2-----> MODEM
+ * *
+PCM3 <------------> * * <----DAI3-----> BT
+ * *
+ * * <----DAI4-----> DMIC
+ * *
+ * * <----DAI5-----> FM
+ *************
+
+This diagram shows a simple smart phone audio subsystem. It supports Bluetooth,
+FM digital radio, Speakers, Headset Jack, digital microphones and cellular
+modem. This sound card exposes 4 DSP front end (FE) ALSA PCM devices and
+supports 6 back end (BE) DAIs. Each FE PCM can digitally route audio data to any
+of the BE DAIs. The FE PCM devices can also route audio to more than 1 BE DAI.
+
+
+
+Example - DPCM Switching playback from DAI0 to DAI1
+---------------------------------------------------
+
+Audio is being played to the Headset. After a while the user removes the headset
+and audio continues playing on the speakers.
+
+Playback on PCM0 to Headset would look like :-
+
+ *************
+PCM0 <============> * * <====DAI0=====> Codec Headset
+ * *
+PCM1 <------------> * * <----DAI1-----> Codec Speakers
+ * DSP *
+PCM2 <------------> * * <----DAI2-----> MODEM
+ * *
+PCM3 <------------> * * <----DAI3-----> BT
+ * *
+ * * <----DAI4-----> DMIC
+ * *
+ * * <----DAI5-----> FM
+ *************
+
+The headset is removed from the jack by user so the speakers must now be used :-
+
+ *************
+PCM0 <============> * * <----DAI0-----> Codec Headset
+ * *
+PCM1 <------------> * * <====DAI1=====> Codec Speakers
+ * DSP *
+PCM2 <------------> * * <----DAI2-----> MODEM
+ * *
+PCM3 <------------> * * <----DAI3-----> BT
+ * *
+ * * <----DAI4-----> DMIC
+ * *
+ * * <----DAI5-----> FM
+ *************
+
+The audio driver processes this as follows :-
+
+ 1) Machine driver receives Jack removal event.
+
+ 2) Machine driver OR audio HAL disables the Headset path.
+
+ 3) DPCM runs the PCM trigger(stop), hw_free(), shutdown() operations on DAI0
+ for headset since the path is now disabled.
+
+ 4) Machine driver or audio HAL enables the speaker path.
+
+ 5) DPCM runs the PCM ops for startup(), hw_params(), prepapre() and
+ trigger(start) for DAI1 Speakers since the path is enabled.
+
+In this example, the machine driver or userspace audio HAL can alter the routing
+and then DPCM will take care of managing the DAI PCM operations to either bring
+the link up or down. Audio playback does not stop during this transition.
+
+
+
+DPCM machine driver
+===================
+
+The DPCM enabled ASoC machine driver is similar to normal machine drivers
+except that we also have to :-
+
+ 1) Define the FE and BE DAI links.
+
+ 2) Define any FE/BE PCM operations.
+
+ 3) Define widget graph connections.
+
+
+1 FE and BE DAI links
+---------------------
+
+| Front End PCMs | SoC DSP | Back End DAIs | Audio devices |
+
+ *************
+PCM0 <------------> * * <----DAI0-----> Codec Headset
+ * *
+PCM1 <------------> * * <----DAI1-----> Codec Speakers
+ * DSP *
+PCM2 <------------> * * <----DAI2-----> MODEM
+ * *
+PCM3 <------------> * * <----DAI3-----> BT
+ * *
+ * * <----DAI4-----> DMIC
+ * *
+ * * <----DAI5-----> FM
+ *************
+
+For the example above we have to define 4 FE DAI links and 6 BE DAI links. The
+FE DAI links are defined as follows :-
+
+static struct snd_soc_dai_link machine_dais[] = {
+ {
+ .name = "PCM0 System",
+ .stream_name = "System Playback",
+ .cpu_dai_name = "System Pin",
+ .platform_name = "dsp-audio",
+ .codec_name = "snd-soc-dummy",
+ .codec_dai_name = "snd-soc-dummy-dai",
+ .dynamic = 1,
+ .trigger = {SND_SOC_DPCM_TRIGGER_POST, SND_SOC_DPCM_TRIGGER_POST},
+ .dpcm_playback = 1,
+ },
+ .....< other FE and BE DAI links here >
+};
+
+This FE DAI link is pretty similar to a regular DAI link except that we also
+set the DAI link to a DPCM FE with the "dynamic = 1". The supported FE stream
+directions should also be set with the "dpcm_playback" and "dpcm_capture"
+flags. There is also an option to specify the ordering of the trigger call for
+each FE. This allows the ASoC core to trigger the DSP before or after the other
+components (as some DSPs have strong requirements for the ordering DAI/DSP
+start and stop sequences).
+
+The FE DAI above sets the codec and code DAIs to dummy devices since the BE is
+dynamic and will change depending on runtime config.
+
+The BE DAIs are configured as follows :-
+
+static struct snd_soc_dai_link machine_dais[] = {
+ .....< FE DAI links here >
+ {
+ .name = "Codec Headset",
+ .cpu_dai_name = "ssp-dai.0",
+ .platform_name = "snd-soc-dummy",
+ .no_pcm = 1,
+ .codec_name = "rt5640.0-001c",
+ .codec_dai_name = "rt5640-aif1",
+ .ignore_suspend = 1,
+ .ignore_pmdown_time = 1,
+ .be_hw_params_fixup = hswult_ssp0_fixup,
+ .ops = &haswell_ops,
+ .dpcm_playback = 1,
+ .dpcm_capture = 1,
+ },
+ .....< other BE DAI links here >
+};
+
+This BE DAI link connects DAI0 to the codec (in this case RT5460 AIF1). It sets
+the "no_pcm" flag to mark it has a BE and sets flags for supported stream
+directions using "dpcm_playback" and "dpcm_capture" above.
+
+The BE has also flags set for ignoring suspend and PM down time. This allows
+the BE to work in a hostless mode where the host CPU is not transferring data
+like a BT phone call :-
+
+ *************
+PCM0 <------------> * * <----DAI0-----> Codec Headset
+ * *
+PCM1 <------------> * * <----DAI1-----> Codec Speakers
+ * DSP *
+PCM2 <------------> * * <====DAI2=====> MODEM
+ * *
+PCM3 <------------> * * <====DAI3=====> BT
+ * *
+ * * <----DAI4-----> DMIC
+ * *
+ * * <----DAI5-----> FM
+ *************
+
+This allows the host CPU to sleep whilst the DSP, MODEM DAI and the BT DAI are
+still in operation.
+
+A BE DAI link can also set the codec to a dummy device if the code is a device
+that is managed externally.
+
+Likewise a BE DAI can also set a dummy cpu DAI if the CPU DAI is managed by the
+DSP firmware.
+
+
+2 FE/BE PCM operations
+----------------------
+
+The BE above also exports some PCM operations and a "fixup" callback. The fixup
+callback is used by the machine driver to (re)configure the DAI based upon the
+FE hw params. i.e. the DSP may perform SRC or ASRC from the FE to BE.
+
+e.g. DSP converts all FE hw params to run at fixed rate of 48k, 16bit, stereo for
+DAI0. This means all FE hw_params have to be fixed in the machine driver for
+DAI0 so that the DAI is running at desired configuration regardless of the FE
+configuration.
+
+static int dai0_fixup(struct snd_soc_pcm_runtime *rtd,
+ struct snd_pcm_hw_params *params)
+{
+ struct snd_interval *rate = hw_param_interval(params,
+ SNDRV_PCM_HW_PARAM_RATE);
+ struct snd_interval *channels = hw_param_interval(params,
+ SNDRV_PCM_HW_PARAM_CHANNELS);
+
+ /* The DSP will covert the FE rate to 48k, stereo */
+ rate->min = rate->max = 48000;
+ channels->min = channels->max = 2;
+
+ /* set DAI0 to 16 bit */
+ snd_mask_set(¶ms->masks[SNDRV_PCM_HW_PARAM_FORMAT -
+ SNDRV_PCM_HW_PARAM_FIRST_MASK],
+ SNDRV_PCM_FORMAT_S16_LE);
+ return 0;
+}
+
+The other PCM operation are the same as for regular DAI links. Use as necessary.
+
+
+3 Widget graph connections
+--------------------------
+
+The BE DAI links will normally be connected to the graph at initialisation time
+by the ASoC DAPM core. However, if the BE codec or BE DAI is a dummy then this
+has to be set explicitly in the driver :-
+
+/* BE for codec Headset - DAI0 is dummy and managed by DSP FW */
+{"DAI0 CODEC IN", NULL, "AIF1 Capture"},
+{"AIF1 Playback", NULL, "DAI0 CODEC OUT"},
+
+
+Writing a DPCM DSP driver
+=========================
+
+The DPCM DSP driver looks much like a standard platform class ASoC driver
+combined with elements from a codec class driver. A DSP platform driver must
+implement :-
+
+ 1) Front End PCM DAIs - i.e. struct snd_soc_dai_driver.
+
+ 2) DAPM graph showing DSP audio routing from FE DAIs to BEs.
+
+ 3) DAPM widgets from DSP graph.
+
+ 4) Mixers for gains, routing, etc.
+
+ 5) DMA configuration.
+
+ 6) BE AIF widgets.
+
+Items 6 is important for routing the audio outside of the DSP. AIF need to be
+defined for each BE and each stream direction. e.g for BE DAI0 above we would
+have :-
+
+SND_SOC_DAPM_AIF_IN("DAI0 RX", NULL, 0, SND_SOC_NOPM, 0, 0),
+SND_SOC_DAPM_AIF_OUT("DAI0 TX", NULL, 0, SND_SOC_NOPM, 0, 0),
+
+The BE AIF are used to connect the DSP graph to the graphs for the other
+component drivers (e.g. codec graph).
+
+
+Hostless PCM streams
+====================
+
+A hostless PCM stream is a stream that is not routed through the host CPU. An
+example of this would be a phone call from handset to modem.
+
+
+ *************
+PCM0 <------------> * * <----DAI0-----> Codec Headset
+ * *
+PCM1 <------------> * * <====DAI1=====> Codec Speakers/Mic
+ * DSP *
+PCM2 <------------> * * <====DAI2=====> MODEM
+ * *
+PCM3 <------------> * * <----DAI3-----> BT
+ * *
+ * * <----DAI4-----> DMIC
+ * *
+ * * <----DAI5-----> FM
+ *************
+
+In this case the PCM data is routed via the DSP. The host CPU in this use case
+is only used for control and can sleep during the runtime of the stream.
+
+The host can control the hostless link either by :-
+
+ 1) Configuring the link as a CODEC <-> CODEC style link. In this case the link
+ is enabled or disabled by the state of the DAPM graph. This usually means
+ there is a mixer control that can be used to connect or disconnect the path
+ between both DAIs.
+
+ 2) Hostless FE. This FE has a virtual connection to the BE DAI links on the DAPM
+ graph. Control is then carried out by the FE as regular PCM operations.
+ This method gives more control over the DAI links, but requires much more
+ userspace code to control the link. Its recommended to use CODEC<->CODEC
+ unless your HW needs more fine grained sequencing of the PCM ops.
+
+
+CODEC <-> CODEC link
+--------------------
+
+This DAI link is enabled when DAPM detects a valid path within the DAPM graph.
+The machine driver sets some additional parameters to the DAI link i.e.
+
+static const struct snd_soc_pcm_stream dai_params = {
+ .formats = SNDRV_PCM_FMTBIT_S32_LE,
+ .rate_min = 8000,
+ .rate_max = 8000,
+ .channels_min = 2,
+ .channels_max = 2,
+};
+
+static struct snd_soc_dai_link dais[] = {
+ < ... more DAI links above ... >
+ {
+ .name = "MODEM",
+ .stream_name = "MODEM",
+ .cpu_dai_name = "dai2",
+ .codec_dai_name = "modem-aif1",
+ .codec_name = "modem",
+ .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_NB_NF
+ | SND_SOC_DAIFMT_CBM_CFM,
+ .params = &dai_params,
+ }
+ < ... more DAI links here ... >
+
+These parameters are used to configure the DAI hw_params() when DAPM detects a
+valid path and then calls the PCM operations to start the link. DAPM will also
+call the appropriate PCM operations to disable the DAI when the path is no
+longer valid.
+
+
+Hostless FE
+-----------
+
+The DAI link(s) are enabled by a FE that does not read or write any PCM data.
+This means creating a new FE that is connected with a virtual path to both
+DAI links. The DAI links will be started when the FE PCM is started and stopped
+when the FE PCM is stopped. Note that the FE PCM cannot read or write data in
+this configuration.

+
+Enables/disables automatic NUMA memory balancing. On NUMA machines, there
+is a performance penalty if remote memory is accessed by a CPU. When this
+feature is enabled the kernel samples what task thread is accessing memory
+by periodically unmapping pages and later trapping a page fault. At the
+time of the page fault, it is determined if the data being accessed should
+be migrated to a local memory node.
+
+The unmapping of pages and trapping faults incur additional overhead that
+ideally is offset by improved memory locality but there is no universal
+guarantee. If the target workload is already bound to NUMA nodes then this
+feature should be disabled. Otherwise, if the system overhead from the
+feature is too high then the rate the kernel samples for NUMA hinting
+faults may be controlled by the numa_balancing_scan_period_min_ms,
+numa_balancing_scan_delay_ms, numa_balancing_scan_period_max_ms,
+numa_balancing_scan_size_mb, numa_balancing_settle_count sysctls and

+==============================================================
+
+numa_balancing_scan_period_min_ms, numa_balancing_scan_delay_ms,
+numa_balancing_scan_period_max_ms, numa_balancing_scan_size_mb
+
+Automatic NUMA balancing scans tasks address space and unmaps pages to
+detect if pages are properly placed or if the data should be migrated to a
+memory node local to where the task is running. Every "scan delay" the task
+scans the next "scan size" number of pages in its address space. When the
+end of the address space is reached the scanner restarts from the beginning.
+
+In combination, the "scan delay" and "scan size" determine the scan rate.
+When "scan delay" decreases, the scan rate increases. The scan delay and
+hence the scan rate of every task is adaptive and depends on historical
+behaviour. If pages are properly placed then the scan delay increases,
+otherwise the scan delay decreases. The "scan size" is not adaptive but
+the higher the "scan size", the higher the scan rate.
+
+Higher scan rates incur higher system overhead as page faults must be
+trapped and potentially data must be migrated. However, the higher the scan
+rate, the more quickly a tasks memory is migrated to a local node if the
+workload pattern changes and minimises performance impact due to remote
+memory accesses. These sysctls control the thresholds for scan delays and
+the number of pages scanned.
+
+numa_balancing_scan_period_min_ms is the minimum time in milliseconds to
+scan a tasks virtual memory. It effectively controls the maximum scanning
+rate for each task.
+
+numa_balancing_scan_delay_ms is the starting "scan delay" used for a task
+when it initially forks.
+
+numa_balancing_scan_period_max_ms is the maximum time in milliseconds to
+scan a tasks virtual memory. It effectively controls the minimum scanning
+rate for each task.
+
+numa_balancing_scan_size_mb is how many megabytes worth of pages are
+scanned for a given scan.
+
+numa_balancing_settle_count is how many scan periods must complete before
+the schedule balancer stops pushing the task towards a preferred node. This
+gives the scheduler a chance to place the task on an alternative node if the
+preferred node is overloaded.
+
+numa_balancing_migrate_deferred is how many page migrations get skipped
+unconditionally, after a page migration is skipped because a page is shared
+with other tasks. This reduces page migration overhead, and determines
+how much stronger the "move task near its memory" policy scheduler becomes,
+versus the "move memory near its task" memory management policy, for workloads
+with shared memory.

-/* Core file format: The core file is written in such a way that gdb
- can understand it and provide useful information to the user (under
- linux we use the 'trad-core' bfd). There are quite a number of
- obstacles to being able to view the contents of the floating point
- registers, and until these are solved you will not be able to view the
- contents of them. Actually, you can read in the core file and look at
- the contents of the user struct to find out what the floating point
- registers contain.
- The actual file contents are as follows:
- UPAGE: 1 page consisting of a user struct that tells gdb what is present
- in the file. Directly after this is a copy of the task_struct, which
- is currently not used by gdb, but it may come in useful at some point.
- All of the registers are stored as part of the upage. The upage should
- always be only one page.
- DATA: The data area is stored. We use current->end_text to
- current->brk to pick up all of the user variables, plus any memory
- that may have been malloced. No attempt is made to determine if a page
- is demand-zero or if a page is totally unused, we just cover the entire
- range. All of the addresses are rounded in such a way that an integral
- number of pages is written.
- STACK: We need the stack information in order to get a meaningful
- backtrace. We need to write the data from (esp) to
- current->start_stack, so we round each of these off in order to be able
- to write an integer number of pages.
- The minimum core file size is 3 pages, or 12288 bytes.

- * A: At some points, the sum (%0) was used as

- * (%1). Thanks to Roman Hodek for pointing this out.
- * B: GCC seems to mess up if one uses too many

- * @addr: Pointer to six-byte array containing the Ethernet address
- * Generates an Ethernet MAC address that is highly likely to be unique for
- * this particular system on a network with other systems of the same type.
- *
- * The problem we are solving is that, when eth_random_addr() is used to
- * generate MAC addresses at startup, there isn't much entropy for the random
- * number generator to use and the addresses it produces are fairly likely to
- * be the same as those of other identical systems on the same local network.
- * This is true even for relatively small numbers of systems (for the reason
- * why, see the Wikipedia entry for "Birthday problem" at:
- * http://en.wikipedia.org/wiki/Birthday_problem
- *
- * The good news is that we already have a MAC address known to be unique, the
- * RF MAC address. The bad news is that this address is already in use on the
- * RF interface. Worse, the obvious trick, taking the RF MAC address and
- * turning on the locally managed bit, has already been used for other devices.
- * Still, this does give us something to work with.
- *
- * The approach we take is:
- * 1. If we can't get the RF MAC Address, just call eth_random_addr.
- * 2. Use the 24-bit NIC-specific bits of the RF MAC address as the last 24
- * bits of the new address. This is very likely to be unique, except for
- * the current box.
- * 3. To avoid using addresses already on the current box, we set the top
- * six bits of the address with a value different from any currently
- * registered Scientific Atlanta organizationally unique identifyer
- * (OUI). This avoids duplication with any addresses on the system that
- * were generated from valid Scientific Atlanta-registered address by
- * simply flipping the locally managed bit.
- * 4. We aren't generating a multicast address, so we leave the multicast
- * bit off. Since we aren't using a registered address, we have to set
- * the locally managed bit.
- * 5. We then randomly generate the remaining 16-bits. This does two
- * things:
- * a. It allows us to call this function for more than one device
- * in this system
- * b. It ensures that things will probably still work even if
- * some device on the device network has a locally managed

- * Author(s): Martin Schwidefsky (schwidefsky@de.ibm.com)
+ * Copyright IBM Corp. 1999,2013
*
- * Derived from "include/asm-i386/bitops.h"

+ * Author(s): Martin Schwidefsky <schwidefsky@de.ibm.com>,
+ *
+ * The description below was taken in large parts from the powerpc
+ * bitops header file:
+ * Within a word, bits are numbered LSB first. Lot's of places make
+ * this assumption by directly testing bits with (val & (1<<nr)).
+ * This can cause confusion for large (> 1 word) bitmaps on a
+ * big-endian system because, unlike little endian, the number of each
+ * bit depends on the word size.
+ *
+ * The bitop functions are defined to work on unsigned longs, so for an
+ * s390x system the bits end up numbered:
+ * |63..............0|127............64|191...........128|255...........196|
+ * and on s390:
+ * |31.....0|63....31|95....64|127...96|159..128|191..160|223..192|255..224|
+ *
+ * There are a few little-endian macros used mostly for filesystem
+ * bitmaps, these work on similar bit arrays layouts, but
+ * byte-oriented:
+ * |7...0|15...8|23...16|31...24|39...32|47...40|55...48|63...56|
+ *
+ * The main difference is that bit 3-5 (64b) or 3-4 (32b) in the bit
+ * number field needs to be reversed compared to the big-endian bit
+ * fields. This can be achieved by XOR with 0x38 (64b) or 0x18 (32b).
+ *
+ * We also have special functions which work with an MSB0 encoding:
+ * on an s390x system the bits are numbered:
+ * |0..............63|64............127|128...........191|192...........255|
+ * and on s390:
+ * |0.....31|31....63|64....95|96...127|128..159|160..191|192..223|224..255|
+ *
+ * The main difference is that bit 0-63 (64b) or 0-31 (32b) in the bit
+ * number field needs to be reversed compared to the LSB0 encoded bit
+ * fields. This can be achieved by XOR with 0x3f (64b) or 0x1f (32b).

-/*
- * the clockevent devices on Moorestown/Medfield can be APBT or LAPIC clock,
- * cmdline option x86_mrst_timer can be used to override the configuration
- * to prefer one or the other.
- * at runtime, there are basically three timer configurations:
- * 1. per cpu apbt clock only
- * 2. per cpu always-on lapic clocks only, this is Penwell/Medfield only
- * 3. per cpu lapic clock (C3STOP) and one apbt clock, with broadcast.
- *
- * by default (without cmdline option), platform code first detects cpu type
- * to see if we are on lincroft or penwell, then set up both lapic or apbt
- * clocks accordingly.
- * i.e. by default, medfield uses configuration #2, moorestown uses #1.
- * config #3 is supported but not recommended on medfield.
- *
- * rating and feature summary:
- * lapic (with C3STOP) --------- 100
- * apbt (always-on) ------------ 110
- * lapic (always-on,ARAT) ------ 150

+ * UV handler for NMI

+ * Handle system-wide NMI events generated by the global 'power nmi' command.

+ * Basic operation is to field the NMI interrupt on each cpu and wait

+ * make it into the handler, try and force them in with the IPI(NMI) signal.
+ *
+ * We also have to lessen UV Hub MMR accesses as much as possible as this
+ * disrupts the UV Hub's primary mission of directing NumaLink traffic and
+ * can cause system problems to occur.
+ *
+ * To do this we register our primary NMI notifier on the NMI_UNKNOWN
+ * chain. This reduces the number of false NMI calls when the perf
+ * tools are running which generate an enormous number of NMIs per
+ * second (~4M/s for 1024 cpu threads). Our secondary NMI handler is
+ * very short as it only checks that if it has been "pinged" with the
+ * IPI(NMI) signal as mentioned above, and does not read the UV Hub's MMR.

+ Certain usages such as Predictive Failure Analysis (PFA) require

+ processor machine check banks. Most server processors log

+ readily make use of them. To complicate matters further, some of
+ the additional error information cannot be constructed without
+ detailed knowledge about platform topology.

+ Enhanced MCA Logging allows firmware to provide additional error
+ information to system software, synchronous with MCE or CMCI. This
+ driver adds support for that functionality.

+ the wfe instruction at a frequency represented as a power-of-2

+ The main use of the event stream is wfe-based timeouts of userspace
+ locking implementations. It might also be useful for imposing timeout

+ * IIO features supported by the driver:
+ *
+ * Read-only raw channels:
+ * - illiminance_clear [lux]
+ * - illiminance_ir
+ * - proximity
+ *
+ * Triggered buffer:
+ * - illiminance_clear
+ * - illiminance_ir
+ * - proximity
+ *
+ * Events:
+ * - illuminance_clear (rising and falling)
+ * - proximity (rising and falling)
+ * - both falling and rising thresholds for the proximity events
+ * must be set to the values greater than 0.
+ *
+ * The driver supports triggered buffers for all the three
+ * channels as well as high and low threshold events for the
+ * illuminance_clear and proxmimity channels. Triggers
+ * can be enabled simultaneously with both illuminance_clear
+ * events. Proximity events cannot be enabled simultaneously
+ * with any triggers or illuminance events. Enabling/disabling
+ * one of the proximity events automatically enables/disables
+ * the other one.

+
+ Due to the potential risks involved with changing e-fuses,

+
+ This driver can also be built as a module. If so, the module

+According to the BF54x HRM, pint means "pin interrupt".
+http://www.analog.com/static/imported-files/processor_manuals/ADSP-BF54x_hwr_rev1.2.pdf
+
+ADSP-BF54x processor Blackfin processors have four SIC interrupt chan-
+nels dedicated to pin interrupt purposes. These channels are managed by
+four hardware blocks, called PINT0, PINT1, PINT2, and PINT3. Every PINTx
+block can sense to up to 32 pins. While PINT0 and PINT1 can sense the
+pins of port A and port B, PINT2 and PINT3 manage all the pins from port
+C to port J as shown in Figure 9-2.
+
+n BF54x HRM:
+The ten GPIO ports are subdivided into 8-bit half ports, resulting in lower and
+upper half 8-bit units. The PINTx_ASSIGN registers control the 8-bit multi-
+plexers shown in Figure 9-3. Lower half units of eight pins can be
+forwarded to either byte 0 or byte 2 of either associated PINTx block.
+Upper half units can be forwarded to either byte 1 or byte 3 of the pin
+interrupt blocks, without further restrictions.
+
+All MMR registers in the pin interrupt module are 32 bits wide. To simply the
+mapping logic, this driver only maps a 16-bit gpio port to the upper or lower
+16 bits of a PINTx block. You can find the Figure 9-3 on page 583.
+
+Each IRQ domain is binding to a GPIO bank device. 2 GPIO bank devices can map
+to one PINT device. Two in "struct gpio_pint" are used to ease the PINT
+interrupt handler.
+
+The GPIO bank mapping to the lower 16 bits of the PINT device set its IRQ
+domain pointer in domain[0]. The IRQ domain pointer of the other bank is set
+to domain[1]. PINT interrupt handler adi_gpio_handle_pint_irq() finds out
+the current domain pointer according to whether the interrupt request mask
+is in lower 16 bits (domain[0]) or upper 16bits (domain[1]).
+
+A PINT device is not part of a GPIO port device in Blackfin. Multiple GPIO
+port devices can be mapped to the same PINT device.

-Driver: comedi_parport
-Description: Standard PC parallel port
-Author: ds
-Status: works in immediate mode
-Devices: [standard] parallel port (comedi_parport)
-Updated: Tue, 30 Apr 2002 21:11:45 -0700
-
-A cheap and easy way to get a few more digital I/O lines. Steal
-additional parallel ports from old computers or your neighbors'
-computers.
-
-Option list:
- 0: I/O port base for the parallel port.
- 1: IRQ
-
-Parallel Port Lines:
-
-pin subdev chan aka
---- ------ ---- ---
-1 2 0 strobe
-2 0 0 data 0
-3 0 1 data 1
-4 0 2 data 2
-5 0 3 data 3
-6 0 4 data 4
-7 0 5 data 5
-8 0 6 data 6
-9 0 7 data 7
-10 1 3 acknowledge
-11 1 4 busy
-12 1 2 output
-13 1 1 printer selected
-14 2 1 auto LF
-15 1 0 error
-16 2 2 init
-17 2 3 select printer
-18-25 ground
-
-Notes:
-
-Subdevices 0 is digital I/O, subdevice 1 is digital input, and
-subdevice 2 is digital output. Unlike other Comedi devices,
-subdevice 0 defaults to output.
-
-Pins 13 and 14 are inverted once by Comedi and once by the
-hardware, thus cancelling the effect.
-
-Pin 1 is a strobe, thus acts like one. There's no way in software
-to change this, at least on a standard parallel port.
-
-Subdevice 3 pretends to be a digital input subdevice, but it always
-returns 0 when read. However, if you run a command with
-scan_begin_src=TRIG_EXT, it uses pin 10 as a external triggering
-pin, which can be used to wake up tasks.

-
-*/
/*
- Dave Andruczyk <dave@tech.buffalostate.edu> also wrote a
- driver for the PCL-711. I used a few ideas from his driver
- here. His driver also has more comments, if you are
- interested in understanding how this driver works.
- http://tech.buffalostate.edu/~dave/driver/
-
- The ACL-8112 driver was hacked from the sources of the PCL-711
- driver (the 744 chip used on the 8112 is almost the same as
- the 711b chip, but it has more I/O channels) by
- Janne Jalkanen (jalkanen@cs.hut.fi) and
- Erik Bunn (ebu@cs.hut.fi). Remerged with the PCL-711 driver
- by ds.
-
- [acl-8112]
- This driver supports both TRIGNOW and TRIGCLK,
- but does not yet support DMA transfers. It also supports
- both high (HG) and low (DG) versions of the card, though
- the HG version has been untested.

+TODO:
+ - Dan Carpenter would like to see some cleanups to the microframe
+ scheduler code:
+ http://www.mail-archive.com/linux-usb@vger.kernel.org/msg26650.html
+
+ - Should merge the NAK holdoff patch from Raspberry Pi
+ (http://marc.info/?l=linux-usb&m=137625067103833). But as it stands
+ that patch is incomplete, it needs more investigation to see if it
+ can be made to work for non-Raspberry Pi platforms that lack the
+ special FIQ interrupt that the Pi has. Without this patch, the driver
+ has a high interrupt rate (8K/sec).
+
+ - The Raspberry Pi platform needs to have support for its FIQ interrupt
+ added, to get the same level of functionality as the downstream
+ driver. The raspberrypi.org developers have indicated they are
+ willing to help with that.
+
+ - Some of the default driver parameters (see 'struct dwc2_core_params'
+ in core.h) won't work for many platforms. So DT attributes will need
+ to be added for some of these. But that can be done as-needed as new
+ platforms are added.
+
+ - Eventually the driver should be merged with the s3c-hsotg peripheral
+ mode driver, so that both modes of operation can be supported with a
+ single driver. But I think that can wait till after the driver has
+ been moved to mainline.
+
+ - After that, OTG support can be added. I'm not sure how much demand
+ there is for that, though, so I have that as a low priority.
+
+Please send any patches for this driver to Paul Zimmerman <paulz@synopsys.com>
+and Greg Kroah-Hartman <gregkh@linuxfoundation.org>. And please CC linux-usb
+<linux-usb@vger.kernel.org> too.

+MXS LRADC driver:
+This is a classic MFD device as it combines the following subdevices
+ - touchscreen controller (input subsystem related device)
+ - general purpose ADC channels
+ - battery voltage monitor (power subsystem related device)
+ - die temperature monitor (thermal management)
+
+At least the battery voltage and die temperature feature is required in-kernel
+by a driver of the SoC's battery charging unit to avoid any damage to the
+silicon and the battery.

1) Open question of userspace vs kernel space balance when

- *
- * @state: USB device state populated by

- * @flags: Optional pipe flags defined in

- * @device_addr:
- * USB device address to open the pipe to
- * (0-127).
- * @endpoint_num:
- * USB endpoint number to open the pipe to
- * (0-15).
- * @device_speed:
- * The speed of the device the pipe is going
- * to. This must match the device's speed,
- * which may be different than the port speed.
- * @max_packet: The maximum packet length the device can
- * transmit/receive (low speed=0-8, full
- * speed=0-1023, high speed=0-1024). This value
- * comes from the standard endpoint descriptor
- * field wMaxPacketSize bits <10:0>.
- * @transfer_type:
- * The type of transfer this pipe is for.
- * @transfer_dir:
- * The direction the pipe is in. This is not
- * used for control pipes.
- * @interval: For ISOCHRONOUS and INTERRUPT transfers,
- * this is how often the transfer is scheduled
- * for. All other transfers should specify
- * zero. The units are in frames (8000/sec at
- * high speed, 1000/sec for full speed).
- * @multi_count:
- * For high speed devices, this is the maximum
- * allowed number of packet per microframe.
- * Specify zero for non high speed devices. This
- * value comes from the standard endpoint descriptor
- * field wMaxPacketSize bits <12:11>.
- * @hub_device_addr:
- * Hub device address this device is connected
- * to. Devices connected directly to Octeon
- * use zero. This is only used when the device
- * is full/low speed behind a high speed hub.
- * The address will be of the high speed hub,
- * not and full speed hubs after it.
- * @hub_port: Which port on the hub the device is
- * connected. Use zero for devices connected
- * directly to Octeon. Like hub_device_addr,
- * this is only used for full/low speed
- * devices behind a high speed hub.
- *
- * Returns: A non negative value is a pipe handle. Negative
- * values are error codes.

-/**
- * "cvmx-usb.h" defines a set of low level USB functions to help
- * developers create Octeon USB drivers for various operating
- * systems. These functions provide a generic API to the Octeon
- * USB blocks, hiding the internal hardware specific
- * operations.
- *
- * At a high level the device driver needs to:
- *
- * - Call cvmx_usb_get_num_ports() to get the number of
- * supported ports.
- * - Call cvmx_usb_initialize() for each Octeon USB port.
- * - Enable the port using cvmx_usb_enable().
- * - Either periodically, or in an interrupt handler, call
- * cvmx_usb_poll() to service USB events.
- * - Manage pipes using cvmx_usb_open_pipe() and
- * cvmx_usb_close_pipe().
- * - Manage transfers using cvmx_usb_submit_*() and
- * cvmx_usb_cancel*().
- * - Shutdown USB on unload using cvmx_usb_shutdown().
- *
- * To monitor USB status changes, the device driver must use
- * cvmx_usb_register_callback() to register for events that it
- * is interested in. Below are a few hints on successfully
- * implementing a driver on top of this API.
- *
- * == Initialization ==
- *
- * When a driver is first loaded, it is normally not necessary
- * to bring up the USB port completely. Most operating systems
- * expect to initialize and enable the port in two independent
- * steps. Normally an operating system will probe hardware,
- * initialize anything found, and then enable the hardware.
- *
- * In the probe phase you should:
- * - Use cvmx_usb_get_num_ports() to determine the number of
- * USB port to be supported.
- * - Allocate space for a struct cvmx_usb_state for each
- * port.
- * - Tell the operating system about each port
- *
- * In the initialization phase you should:
- * - Use cvmx_usb_initialize() on each port.
- * - Do not call cvmx_usb_enable(). This leaves the USB port in
- * the disabled state until the operating system is ready.
- *
- * Finally, in the enable phase you should:
- * - Call cvmx_usb_enable() on the appropriate port.
- * - Note that some operating system use a RESET instead of an
- * enable call. To implement RESET, you should call
- * cvmx_usb_disable() followed by cvmx_usb_enable().
- *
- * == Locking ==
- *
- * All of the functions in the cvmx-usb API assume exclusive
- * access to the USB hardware and internal data structures. This
- * means that the driver must provide locking as necessary.
- *
- * In the single CPU state it is normally enough to disable
- * interrupts before every call to cvmx_usb*() and enable them
- * again after the call is complete. Keep in mind that it is
- * very common for the callback handlers to make additional
- * calls into cvmx-usb, so the disable/enable must be protected
- * against recursion. As an example, the Linux kernel
- * local_irq_save() and local_irq_restore() are perfect for this
- * in the non SMP case.
- *
- * In the SMP case, locking is more complicated. For SMP you not
- * only need to disable interrupts on the local core, but also
- * take a lock to make sure that another core cannot call
- * cvmx-usb.
- *
- * == Port callback ==
- *
- * The port callback prototype needs to look as follows:
- *
- * void port_callback(struct cvmx_usb_state *usb,
- * enum cvmx_usb_callback reason,
- * enum cvmx_usb_complete status,
- * int pipe_handle,
- * int submit_handle,
- * int bytes_transferred,
- * void *user_data);
- * - "usb" is the struct cvmx_usb_state for the port.
- * - "reason" will always be CVMX_USB_CALLBACK_PORT_CHANGED.
- * - "status" will always be CVMX_USB_COMPLETE_SUCCESS.
- * - "pipe_handle" will always be -1.
- * - "submit_handle" will always be -1.
- * - "bytes_transferred" will always be 0.
- * - "user_data" is the void pointer originally passed along
- * with the callback. Use this for any state information you
- * need.
- *
- * The port callback will be called whenever the user plugs /
- * unplugs a device from the port. It will not be called when a
- * device is plugged / unplugged from a hub connected to the
- * root port. Normally all the callback needs to do is tell the
- * operating system to poll the root hub for status. Under
- * Linux, this is performed by calling usb_hcd_poll_rh_status().
- * In the Linux driver we use "user_data". to pass around the
- * Linux "hcd" structure. Once the port callback completes,
- * Linux automatically calls octeon_usb_hub_status_data() which
- * uses cvmx_usb_get_status() to determine the root port status.
- *
- * == Complete callback ==
- *
- * The completion callback prototype needs to look as follows:
- *
- * void complete_callback(struct cvmx_usb_state *usb,
- * enum cvmx_usb_callback reason,
- * enum cvmx_usb_complete status,
- * int pipe_handle,
- * int submit_handle,
- * int bytes_transferred,
- * void *user_data);
- * - "usb" is the struct cvmx_usb_state for the port.
- * - "reason" will always be CVMX_USB_CALLBACK_TRANSFER_COMPLETE.
- * - "status" will be one of the cvmx_usb_complete enumerations.
- * - "pipe_handle" is the handle to the pipe the transaction
- * was originally submitted on.
- * - "submit_handle" is the handle returned by the original
- * cvmx_usb_submit_* call.
- * - "bytes_transferred" is the number of bytes successfully
- * transferred in the transaction. This will be zero on most
- * error conditions.
- * - "user_data" is the void pointer originally passed along
- * with the callback. Use this for any state information you
- * need. For example, the Linux "urb" is stored in here in the
- * Linux driver.
- *
- * In general your callback handler should use "status" and
- * "bytes_transferred" to tell the operating system the how the
- * transaction completed. Normally the pipe is not changed in
- * this callback.
- *
- * == Canceling transactions ==
- *
- * When a transaction is cancelled using cvmx_usb_cancel*(), the
- * actual length of time until the complete callback is called
- * can vary greatly. It may be called before cvmx_usb_cancel*()
- * returns, or it may be called a number of usb frames in the
- * future once the hardware frees the transaction. In either of
- * these cases, the complete handler will receive
- * CVMX_USB_COMPLETE_CANCEL.
- *
- * == Handling pipes ==
- *
- * USB "pipes" is a software construct created by this API to
- * enable the ordering of usb transactions to a device endpoint.
- * Octeon's underlying hardware doesn't have any concept
- * equivalent to "pipes". The hardware instead has eight
- * channels that can be used simultaneously to have up to eight
- * transaction in process at the same time. In order to maintain
- * ordering in a pipe, the transactions for a pipe will only be
- * active in one hardware channel at a time. From an API user's
- * perspective, this doesn't matter but it can be helpful to
- * keep this in mind when you are probing hardware while
- * debugging.
- *
- * Also keep in mind that usb transactions contain state
- * information about the previous transaction to the same
- * endpoint. Each transaction has a PID toggle that changes 0/1
- * between each sub packet. This is maintained in the pipe data
- * structures. For this reason, you generally cannot create and
- * destroy a pipe for every transaction. A sequence of
- * transaction to the same endpoint must use the same pipe.
- *
- * == Root Hub ==
- *
- * Some operating systems view the usb root port as a normal usb
- * hub. These systems attempt to control the root hub with
- * messages similar to the usb 2.0 spec for hub control and
- * status. For these systems it may be necessary to write
- * function to decode standard usb control messages into
- * equivalent cvmx-usb API calls.
- *
- * == Interrupts ==
- *
- * If you plan on using usb interrupts, cvmx_usb_poll() must be
- * called on every usb interrupt. It will read the usb state,
- * call any needed callbacks, and schedule transactions as
- * needed. Your device driver needs only to hookup an interrupt
- * handler and call cvmx_usb_poll(). Octeon's usb port 0 causes
- * CIU bit CIU_INT*_SUM0[USB] to be set (bit 56). For port 1,
- * CIU bit CIU_INT_SUM1[USB1] is set (bit 17). How these bits
- * are turned into interrupt numbers is operating system
- * specific. For Linux, there are the convenient defines
- * OCTEON_IRQ_USB0 and OCTEON_IRQ_USB1 for the IRQ numbers.
- *
- * If you aren't using interrupts, simple call cvmx_usb_poll()
- * in your main processing loop.

- * @desc: array of ngpio descriptors. Private.
- * @can_sleep: flag must be set iff get()/set() methods sleep, as they
- * must while accessing GPIO expander chips over I2C or SPI
- * @names: if set, must be an array of strings to use as alternative
- * names for the GPIOs in this chip. Any entry in the array
- * may be NULL if there is no alias for the GPIO, however the

- * Example sources would be SOC controllers, FPGAs, multifunction

- * by "offset" values in the range 0..(@ngpio - 1). When those signals
- * are referenced through calls like gpio_get_value(gpio), the offset

+ * struct gpio_chip - abstract a GPIO controller
+ * @label: for diagnostics
+ * @dev: optional device providing the GPIOs
+ * @owner: helps prevent removal of modules exporting active GPIOs
+ * @list: links gpio_chips together for traversal
+ * @request: optional hook for chip-specific activation, such as
+ * enabling module power and clock; may sleep
+ * @free: optional hook for chip-specific deactivation, such as
+ * disabling module power and clock; may sleep
+ * @get_direction: returns direction for signal "offset", 0=out, 1=in,
+ * (same as GPIOF_DIR_XXX), or negative error
+ * @direction_input: configures signal "offset" as input, or returns error
+ * @direction_output: configures signal "offset" as output, or returns error
+ * @get: returns value for signal "offset"; for output signals this
+ * returns either the value actually sensed, or zero
+ * @set: assigns output value for signal "offset"
+ * @set_debounce: optional hook for setting debounce time for specified gpio in
+ * interrupt triggered gpio chips
+ * @to_irq: optional hook supporting non-static gpio_to_irq() mappings;
+ * implementation may not sleep
+ * @dbg_show: optional routine to show contents in debugfs; default code
+ * will be used when this is omitted, but custom code can show extra
+ * state (such as pullup/pulldown configuration).
+ * @base: identifies the first GPIO number handled by this chip; or, if
+ * negative during registration, requests dynamic ID allocation.
+ * @ngpio: the number of GPIOs handled by this controller; the last GPIO
+ * handled is (base + ngpio - 1).
+ * @desc: array of ngpio descriptors. Private.
+ * @can_sleep: flag must be set iff get()/set() methods sleep, as they
+ * must while accessing GPIO expander chips over I2C or SPI
+ * @names: if set, must be an array of strings to use as alternative
+ * names for the GPIOs in this chip. Any entry in the array
+ * may be NULL if there is no alias for the GPIO, however the
+ * array must be @ngpio entries long. A name can include a single printk
+ * format specifier for an unsigned int. It is substituted by the actual
+ * number of the gpio.
+ *
+ * A gpio_chip can help platforms abstract various sources of GPIOs so
+ * they can all be accessed through a common programing interface.
+ * Example sources would be SOC controllers, FPGAs, multifunction
+ * chips, dedicated GPIO expanders, and so on.
+ *
+ * Each chip controls a number of signals, identified in method calls
+ * by "offset" values in the range 0..(@ngpio - 1). When those signals
+ * are referenced through calls like gpio_get_value(gpio), the offset
+ * is calculated by subtracting @base from the gpio number.

+ * kcore_copy - copy kallsyms, modules and kcore from one directory to another.
+ * @from_dir: from directory
+ * @to_dir: to directory
+ *
+ * This function copies kallsyms, modules and kcore files from one directory to
+ * another. kallsyms and modules are copied entirely. Only code segments are
+ * copied from kcore. It is assumed that two segments suffice: one for the
+ * kernel proper and one for all the modules. The code segments are determined
+ * from kallsyms and modules files. The kernel map starts at _stext or the
+ * lowest function symbol, and ends at _etext or the highest function symbol.
+ * The module map starts at the lowest module address and ends at the highest
+ * module symbol. Start addresses are rounded down to the nearest page. End
+ * addresses are rounded up to the nearest page. An extra page is added to the
+ * highest kernel symbol and highest module symbol to, hopefully, encompass that
+ * symbol too. Because it contains only code sections, the resulting kcore is
+ * unusual. One significant peculiarity is that the mapping (start -> pgoff)
+ * is not the same for the kernel map and the modules map. That happens because
+ * the data is copied adjacently whereas the original kcore has gaps. Finally,
+ * kallsyms and modules files are compared with their copies to check that
+ * modules have not been loaded or unloaded while the copies were taking place.
+ *
+ * Return: %0 on success, %-1 on failure.
