		Rockchip processors include support for multiple power domains
		which can be powered up/down by software based on different
		application scenarios to save power.

		Power domains contained within power-controller node are
		generic power domain providers documented in
		Documentation/devicetree/bindings/power/power-domain.yaml.

		IP cores belonging to a power domain should contain a
		"power-domains" property that is a phandle for the
		power domain node representing the domain.

		* Rockchip Power Domains

		Rockchip processors include support for multiple power domains which can be
		powered up/down by software based on different application scenes to save power.

		Required properties for power domain controller:
		- compatible: Should be one of the following.
		"rockchip,px30-power-controller" - for PX30 SoCs.
		"rockchip,rk3036-power-controller" - for RK3036 SoCs.
		"rockchip,rk3066-power-controller" - for RK3066 SoCs.
		"rockchip,rk3128-power-controller" - for RK3128 SoCs.
		"rockchip,rk3188-power-controller" - for RK3188 SoCs.
		"rockchip,rk3228-power-controller" - for RK3228 SoCs.
		"rockchip,rk3288-power-controller" - for RK3288 SoCs.
		"rockchip,rk3328-power-controller" - for RK3328 SoCs.
		"rockchip,rk3366-power-controller" - for RK3366 SoCs.
		"rockchip,rk3368-power-controller" - for RK3368 SoCs.
		"rockchip,rk3399-power-controller" - for RK3399 SoCs.
		- #power-domain-cells: Number of cells in a power-domain specifier.
		Should be 1 for multiple PM domains.
		- #address-cells: Should be 1.
		- #size-cells: Should be 0.

		Required properties for power domain sub nodes:
		- reg: index of the power domain, should use macros in:
		"include/dt-bindings/power/px30-power.h" - for PX30 type power domain.
		"include/dt-bindings/power/rk3036-power.h" - for RK3036 type power domain.
		"include/dt-bindings/power/rk3066-power.h" - for RK3066 type power domain.
		"include/dt-bindings/power/rk3128-power.h" - for RK3128 type power domain.
		"include/dt-bindings/power/rk3188-power.h" - for RK3188 type power domain.
		"include/dt-bindings/power/rk3228-power.h" - for RK3228 type power domain.
		"include/dt-bindings/power/rk3288-power.h" - for RK3288 type power domain.
		"include/dt-bindings/power/rk3328-power.h" - for RK3328 type power domain.
		"include/dt-bindings/power/rk3366-power.h" - for RK3366 type power domain.
		"include/dt-bindings/power/rk3368-power.h" - for RK3368 type power domain.
		"include/dt-bindings/power/rk3399-power.h" - for RK3399 type power domain.
		- clocks (optional): phandles to clocks which need to be enabled while power domain
		switches state.
		- pm_qos (optional): phandles to qos blocks which need to be saved and restored
		while power domain switches state.

		Qos Example:

		qos_gpu: qos_gpu@ffaf0000 {
		compatible ="syscon";
		reg = <0x0 0xffaf0000 0x0 0x20>;
		};

		Example:

		power: power-controller {
		compatible = "rockchip,rk3288-power-controller";
		#power-domain-cells = <1>;
		#address-cells = <1>;
		#size-cells = <0>;

		pd_gpu {
		reg = <RK3288_PD_GPU>;
		clocks = <&cru ACLK_GPU>;
		pm_qos = <&qos_gpu>;
		};
		};

		power: power-controller {
		compatible = "rockchip,rk3368-power-controller";
		#power-domain-cells = <1>;
		#address-cells = <1>;
		#size-cells = <0>;

		pd_gpu_1 {
		reg = <RK3368_PD_GPU_1>;
		clocks = <&cru ACLK_GPU_CFG>;
		};
		};

		Example 2:
		power: power-controller {
		compatible = "rockchip,rk3399-power-controller";
		#power-domain-cells = <1>;
		#address-cells = <1>;
		#size-cells = <0>;

		pd_vio {
		#address-cells = <1>;
		#size-cells = <0>;
		reg = <RK3399_PD_VIO>;

		pd_vo {
		#address-cells = <1>;
		#size-cells = <0>;
		reg = <RK3399_PD_VO>;

		pd_vopb {
		reg = <RK3399_PD_VOPB>;
		};

		pd_vopl {
		reg = <RK3399_PD_VOPL>;
		};
		};
		};
		};

		Node of a device using power domains must have a power-domains property,
		containing a phandle to the power device node and an index specifying which
		power domain to use.
		The index should use macros in:
		"include/dt-bindings/power/px30-power.h" - for px30 type power domain.
		"include/dt-bindings/power/rk3036-power.h" - for rk3036 type power domain.
		"include/dt-bindings/power/rk3128-power.h" - for rk3128 type power domain.
		"include/dt-bindings/power/rk3128-power.h" - for rk3228 type power domain.
		"include/dt-bindings/power/rk3288-power.h" - for rk3288 type power domain.
		"include/dt-bindings/power/rk3328-power.h" - for rk3328 type power domain.
		"include/dt-bindings/power/rk3366-power.h" - for rk3366 type power domain.
		"include/dt-bindings/power/rk3368-power.h" - for rk3368 type power domain.
		"include/dt-bindings/power/rk3399-power.h" - for rk3399 type power domain.

		Example of the node using power domain:

		node {
		/* ... */
		power-domains = <&power RK3288_PD_GPU>;
		/* ... */
		};

		node {
		/* ... */
		power-domains = <&power RK3368_PD_GPU_1>;
		/* ... */
		};

		node {
		/* ... */
		power-domains = <&power RK3399_PD_VOPB>;
		/* ... */
		};
