* Realtek Power Controller

Support for multiple power domains which are used to gate power to one or more
peripherals on the processor.

==PM domain providers==

Required Properties:
- compatible: "realtek,rts3915-power-controller"
- reg: Physical base address of the controller and length of memory mapped
    region.
- #power-domain-cells: Number of cells in power domain specifier;
    must be 1.

Example:

	power: power-controller@188dc000 {
		compatible = "realtek,rts3915-power-controller";
		reg = <0x188dc000 0x1000>;
		#power-domain-cells = <1>;
	};

==PM domain consumers==

Node of a device using power domains must have a power-domains property
defined with a phandle to respective power domain.

Required properties:
 - power-domains : A phandle and PM domain specifier as defined by bindings of
                   the power controller specified by phandle.
		   <dt-bindings/power/rts-power.h>.

Example:

	crypto: crypto@18600000 {
		...
		power-domains = <&power RTS_PD_TOP_OFF>;
		...
	};
