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

    maxItems: 1

  '#clock-cells':
