* Hisilicon Hi3620 Clock Controller
|
||||
|
||||
The Hi3620 clock controller generates and supplies clock to various
|
||||
controllers within the Hi3620 SoC.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: should be one of the following.
|
||||
- "hisilicon,hi3620-clock" - controller compatible with Hi3620 SoC.
|
||||
|
||||
- reg: physical base address of the controller and length of memory mapped
|
||||
region.
|
||||
|
||||
- #clock-cells: should be 1.
|
||||
|
||||
Each clock is assigned an identifier and client nodes use this identifier
|
||||
to specify the clock which they consume.
|
||||
|
||||
All these identifier could be found in <dt-bindings/clock/hi3620-clock.h>.
