description: |
  Hisilicon designs some special domain controllers for mobile platform,
  such as: the power Always On domain controller, the Media domain
  controller(e.g. codec, G3D ...) and the Power Management domain
  controller.

  The compatible names of each domain controller are as follows:
  Power Always ON domain controller  --> hisilicon,hi6220-aoctrl
  Media domain controller            --> hisilicon,hi6220-mediactrl
  Power Management domain controller --> hisilicon,hi6220-pmctrl

properties:
  compatible:
    items:
      - enum:
          - hisilicon,hi6220-aoctrl
          - hisilicon,hi6220-mediactrl
          - hisilicon,hi6220-pmctrl
      - const: syscon

  reg:
    maxItems: 1

  '#clock-cells':
    const: 1

  '#reset-cells':
    const: 1

required:
  - compatible
  - reg
  - '#clock-cells'

additionalProperties: false

  - |
    ao_ctrl@f7800000 {
        compatible = "hisilicon,hi6220-aoctrl", "syscon";
        reg = <0xf7800000 0x2000>;
        #clock-cells = <1>;
        #reset-cells = <1>;
    };

    media_ctrl@f4410000 {
        compatible = "hisilicon,hi6220-mediactrl", "syscon";
