* Actions S900 Clock Management Unit (CMU)

* Actions Semi Owl Clock Management Unit (CMU)

The Actions S900 clock management unit generates and supplies clock to various

controllers within the SoC. The clock binding described here is applicable to

S900 SoC.

The Actions Semi Owl Clock Management Unit generates and supplies clock

to various controllers within the SoC. The clock binding described here is

applicable to S900 and S700 SoC's.

Required Properties:

- compatible: should be "actions,s900-cmu"

- compatible: should be one of the following,

	"actions,s900-cmu"

	"actions,s700-cmu"

- reg: physical base address of the controller and length of memory mapped

  region.

- clocks: Reference to the parent clocks ("hosc", "losc")

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

dt-bindings/clock/actions,s900-cmu.h header and can be used in device

tree sources.

All available clocks are defined as preprocessor macros in corresponding

dt-bindings/clock/actions,s900-cmu.h or actions,s700-cmu.h header and can be

used in device tree sources.

External clocks:

The hosc clock used as input for the plls is generated outside the SoC. It is

expected that it is defined using standard clock bindings as "hosc".

Actions S900 CMU also requires one more clock:

Actions Semi S900 CMU also requires one more clock:

 - "losc" - internal low frequency oscillator

------------------------------------------------------------

Required properties :

- compatible : shall contain "qcom,sdm845-dispcc"

- reg : shall contain base register location and length.

- #clock-cells : from common clock binding, shall contain 1.

- #reset-cells : from common reset binding, shall contain 1.

- #power-domain-cells : from generic power domain binding, shall contain 1.

Example:

	dispcc: clock-controller@af00000 {

		compatible = "qcom,sdm845-dispcc";

		reg = <0xaf00000 0x100000>;

		#clock-cells = <1>;

		#reset-cells = <1>;

		#power-domain-cells = <1>;
