* Hisilicon Hi6220 Clock Controller
|
||
|
|
||
|
Clock control registers reside in different Hi6220 system controllers,
|
||
|
please refer the following document to know more about the binding rules
|
||
|
for these system controllers:
|
||
|
|
||
|
Documentation/devicetree/bindings/arm/hisilicon/hisilicon.txt
|
||
|
|
||
|
Required Properties:
|
||
|
|
||
|
- compatible: the compatible should be one of the following strings to
|
||
|
indicate the clock controller functionality.
|
||
|
|
||
|
- "hisilicon,hi6220-aoctrl"
|
||
|
- "hisilicon,hi6220-sysctrl"
|
||
|
- "hisilicon,hi6220-mediactrl"
|
||
|
- "hisilicon,hi6220-pmctrl"
|
||
|
|
||
|
- reg: physical base address of the controller and length of memory mapped
|
||
|
region.
|
||
|
|
||
|
- #clock-cells: should be 1.
|
||
|
|
||
|
For example:
|
||
|
sys_ctrl: sys_ctrl@f7030000 {
|
||
|
compatible = "hisilicon,hi6220-sysctrl", "syscon";
|
||
|
reg = <0x0 0xf7030000 0x0 0x2000>;
|
||
|
#clock-cells = <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/hi6220-clock.h>.
