Hisilicon Hi6220 system controller



Required properties:

- compatible : "hisilicon,hi6220-sysctrl"

- 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 controller as one of the system controllers,

its main functions are the same as Hisilicon system controller, but

the register offset of some core modules are different.



Example:

	/*for Hi6220*/

	sys_ctrl: sys_ctrl@f7030000 {

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

		reg = <0x0 0xf7030000 0x0 0x2000>;

		#clock-cells = <1>;

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";

- 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 {

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:
