* 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")
@ -15,16 +17,16 @@ Required Properties:
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
Example: Clock Management Unit node:
