+Hisilicon's SoCs use sram for multiple purpose; on Hi6220 there have several
+SRAM banks for power management, modem, security, etc. Further, use "syscon"
+managing the common sram which can be shared by multiple modules.
+
+Example:
+	/*for Hi6220*/
+	sram: sram@fff80000 {
+		compatible = "hisilicon,hi6220-sramctrl", "syscon";
+		reg = <0x0 0xfff80000 0x0 0x12000>;

+NVIDIA Tegra124 DFLL FCPU clocksource
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The DFLL IP block on Tegra is a root clocksource designed for clocking
+the fast CPU cluster. It consists of a free-running voltage controlled
+oscillator connected to the CPU voltage rail (VDD_CPU), and a closed loop
+control module that will automatically adjust the VDD_CPU voltage by
+communicating with an off-chip PMIC either via an I2C bus or via PWM signals.
+Currently only the I2C mode is supported by these bindings.
+
+Required properties:
+- compatible : should be "nvidia,tegra124-dfll"
+- reg : Defines the following set of registers, in the order listed:
+        - registers for the DFLL control logic.
+        - registers for the I2C output logic.
+        - registers for the integrated I2C master controller.
+        - look-up table RAM for voltage register values.
+- interrupts: Should contain the DFLL block interrupt.
+- clocks: Must contain an entry for each entry in clock-names.
+  See clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+  - soc: Clock source for the DFLL control logic.
+  - ref: The closed loop reference clock
+  - i2c: Clock source for the integrated I2C master.
+- resets: Must contain an entry for each entry in reset-names.
+  See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+  - dvco: Reset control for the DFLL DVCO.
+- #clock-cells: Must be 0.
+- clock-output-names: Name of the clock output.
+- vdd-cpu-supply: Regulator for the CPU voltage rail that the DFLL
+  hardware will start controlling. The regulator will be queried for
+  the I2C register, control values and supported voltages.
+
+Required properties for the control loop parameters:
+- nvidia,sample-rate: Sample rate of the DFLL control loop.
+- nvidia,droop-ctrl: See the register CL_DVFS_DROOP_CTRL in the TRM.
+- nvidia,force-mode: See the field DFLL_PARAMS_FORCE_MODE in the TRM.
+- nvidia,cf: Numeric value, see the field DFLL_PARAMS_CF_PARAM in the TRM.
+- nvidia,ci: Numeric value, see the field DFLL_PARAMS_CI_PARAM in the TRM.
+- nvidia,cg: Numeric value, see the field DFLL_PARAMS_CG_PARAM in the TRM.
+
+Optional properties for the control loop parameters:
+- nvidia,cg-scale: Boolean value, see the field DFLL_PARAMS_CG_SCALE in the TRM.
+
+Required properties for I2C mode:

+* Rockchip RK3368 Clock and Reset Unit
+
+The RK3368 clock controller generates and supplies clock to various
+controllers within the SoC and also implements a reset controller for SoC
+peripherals.
+
+Required Properties:
+
+- compatible: should be "rockchip,rk3368-cru"
+- reg: physical base address of the controller and length of memory mapped
+  region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Optional Properties:
+
+- rockchip,grf: phandle to the syscon managing the "general register files"
+  If missing, pll rates are not changeable, due to the missing pll lock status.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/rk3368-cru.h headers and can be
+used in device tree sources. Similar macros exist for the reset sources in
+these files.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "xin32k" - rtc clock - optional,
+ - "ext_i2s" - external I2S clock - optional,
+ - "ext_gmac" - external GMAC clock - optional
+ - "ext_hsadc" - external HSADC clock - optional,
+ - "ext_isp" - external ISP clock - optional,
+ - "ext_jtag" - external JTAG clock - optional
+ - "ext_vip" - external VIP clock - optional,
+ - "usbotg_out" - output clock of the pll in the otg phy
+
+Example: Clock controller node:
+
+	cru: clock-controller@ff760000 {
+		compatible = "rockchip,rk3368-cru";
+		reg = <0x0 0xff760000 0x0 0x1000>;
+		rockchip,grf = <&grf>;
+		#clock-cells = <1>;
+		#reset-cells = <1>;
+	};
+
+Example: UART controller node that consumes the clock generated by the clock
+  controller:
+
+	uart0: serial@10124000 {
+		compatible = "snps,dw-apb-uart";
+		reg = <0x10124000 0x400>;
+		interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>;
+		reg-shift = <2>;
+		reg-io-width = <1>;
+		clocks = <&cru SCLK_UART0>;

+  clock in the prcmu-clock node the consumer wants to use.

+  PRCC (programmable reset- and clock controller) peripheral clocks.
+  The first cell indicates which PRCC block the consumer
+  wants to use, possible values are 1, 2, 3, 5, 6. The second
+  cell indicates which clock inside the PRCC block it wants,
+  possible values are 0 thru 31.
+- prcc-kernel-clock: a subnode with two clock cells for
+  PRCC (programmable reset- and clock controller) kernel clocks
+  The first cell indicates which PRCC block the consumer
+  wants to use, possible values are 1, 2, 3, 5, 6. The second
+  cell indicates which clock inside the PRCC block it wants,
+  possible values are 0 thru 31.

+  RTC clock.

+  with zero clock cells.

- * clksel clocks are clocks that do not have a fixed parent, or that
- * can divide their parent's rate, or possibly both at the same time, based
- * on the contents of a hardware register bitfield.
- *
- * All of the various mux and divider settings can be encoded into
- * struct clksel* data structures, and then these can be autogenerated
- * from some hardware database for each new chip generation.  This
- * should avoid the need to write, review, and validate a lot of new
- * clock code for each new chip, since it can be exported from the SoC
- * design flow.  This is now done on OMAP4.
- *
- * The fusion of mux and divider clocks is a software creation.  In
- * hardware reality, the multiplexer (parent selection) and the
- * divider exist separately.  XXX At some point these clksel clocks
- * should be split into "divider" clocks and "mux" clocks to better
- * match the hardware.
- *
- * (The name "clksel" comes from the name of the corresponding
- * register field in the OMAP2/3 family of SoCs.)
- *
- * XXX Currently these clocks are only used in the OMAP2/3/4 code, but
- * many of the OMAP1 clocks should be convertible to use this
- * mechanism.

+ * This library is for the DVCO and DFLL IP blocks on the Tegra124
+ * SoC. These IP blocks together are also known at NVIDIA as
+ * "CL-DVFS". To try to avoid confusion, this code refers to them
+ * collectively as the "DFLL."
+ *
+ * The DFLL is a root clocksource which tolerates some amount of
+ * supply voltage noise. Tegra124 uses it to clock the fast CPU
+ * complex when the target CPU speed is above a particular rate. The
+ * DFLL can be operated in either open-loop mode or closed-loop mode.
+ * In open-loop mode, the DFLL generates an output clock appropriate
+ * to the supply voltage. In closed-loop mode, when configured with a
+ * target frequency, the DFLL minimizes supply voltage while
+ * delivering an average frequency equal to the target.
+ *
+ * Devices clocked by the DFLL must be able to tolerate frequency
+ * variation. In the case of the CPU, it's important to note that the
+ * CPU cycle time will vary. This has implications for
+ * performance-measurement code and any code that relies on the CPU
+ * cycle time to delay for a certain length of time.
