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>;

        #reset-cells = <1>;

    };

    media_ctrl@f4410000 {

        compatible = "hisilicon,hi6220-mediactrl", "syscon";

        reg = <0xf4410000 0x1000>;

Hisilicon Hi6220 Power Always ON domain controller

Required properties:

- compatible : "hisilicon,hi6220-aoctrl"

- reg : Register address and size

- #clock-cells: should be set to 1, many clock registers are defined

  under this controller and this property must be present.

Hisilicon designs this system controller to control the power always

on domain for mobile platform.

Example:

	/*for Hi6220*/

	ao_ctrl: ao_ctrl@f7800000 {

		compatible = "hisilicon,hi6220-aoctrl", "syscon";

		reg = <0x0 0xf7800000 0x0 0x2000>;

		#clock-cells = <1>;

	};

Hisilicon Hi6220 Media domain controller

Required properties:

- compatible : "hisilicon,hi6220-mediactrl"

- reg : Register address and size

- #clock-cells: should be set to 1, many clock registers are defined

  under this controller and this property must be present.

Hisilicon designs this system controller to control the multimedia

domain(e.g. codec, G3D ...) for mobile platform.

Example:

	/*for Hi6220*/

	media_ctrl: media_ctrl@f4410000 {

		compatible = "hisilicon,hi6220-mediactrl", "syscon";

		reg = <0x0 0xf4410000 0x0 0x1000>;

		#clock-cells = <1>;

	};

Hisilicon Hi6220 Power Management domain controller

Required properties:

- compatible : "hisilicon,hi6220-pmctrl"

- reg : Register address and size

- #clock-cells: should be set to 1, some clock registers are define

  under this controller and this property must be present.

Hisilicon designs this system controller to control the power management

domain for mobile platform.

Example:

	/*for Hi6220*/

	pm_ctrl: pm_ctrl@f7032000 {

		compatible = "hisilicon,hi6220-pmctrl", "syscon";

		reg = <0x0 0xf7032000 0x0 0x1000>;

		#clock-cells = <1>;

	};
