* Actions S900 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.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: should be "actions,s900-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.
|
||||
|
||||
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.
|
||||
|
||||
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:
|
||||
- "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>;
|
||||
};
|
||||
|
||||
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>;
|
||||
};
