1 * Hisilicon Hi6220 Clock Controller
3 Clock control registers reside in different Hi6220 system controllers,
4 please refer the following document to know more about the binding rules
5 for these system controllers:
7 Documentation/devicetree/bindings/arm/hisilicon/hisilicon.txt
11 - compatible: the compatible should be one of the following strings to
12 indicate the clock controller functionality.
14 - "hisilicon,hi6220-aoctrl"
15 - "hisilicon,hi6220-sysctrl"
16 - "hisilicon,hi6220-mediactrl"
17 - "hisilicon,hi6220-pmctrl"
19 - reg: physical base address of the controller and length of memory mapped
22 - #clock-cells: should be 1.
25 sys_ctrl: sys_ctrl@f7030000 {
26 compatible = "hisilicon,hi6220-sysctrl", "syscon";
27 reg = <0x0 0xf7030000 0x0 0x2000>;
31 Each clock is assigned an identifier and client nodes use this identifier
32 to specify the clock which they consume.
34 All these identifier could be found in <dt-bindings/clock/hi6220-clock.h>.
