-* Actions Semi Owl Clock Management Unit (CMU)
-
-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, S700 and S500 SoC's.
-
-Required Properties:
-
-- compatible: should be one of the following,
- "actions,s900-cmu"
- "actions,s700-cmu"
- "actions,s500-cmu"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- clocks: Reference to the parent clocks ("hosc", "losc")
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-
-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 corresponding
-dt-bindings/clock/actions,s900-cmu.h or actions,s700-cmu.h or
-actions,s500-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 Semi S900 CMU also requires one more clock:
- - "losc" - internal low frequency oscillator
-
-Example: Clock Management Unit node:
-
- cmu: clock-controller@e0160000 {
- compatible = "actions,s900-cmu";
- reg = <0x0 0xe0160000 0x0 0x1000>;
- clocks = <&hosc>, <&losc>;
- #clock-cells = <1>;
- #reset-cells = <1>;
- };
-
-Example: UART controller node that consumes clock generated by the clock
-management unit:
-
- uart: serial@e012a000 {
- compatible = "actions,s900-uart", "actions,owl-uart";
- reg = <0x0 0xe012a000 0x0 0x2000>;
- interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cmu CLK_UART5>;
- };
