* Samsung Exynos Power Domains



Exynos processors include support for multiple power domains which are used

to gate power to one or more peripherals on the processor.



Required Properties:

- compatible: should be one of the following.

    * samsung,exynos4210-pd - for exynos4210 type power domain.

    * samsung,exynos5433-pd - for exynos5433 type power domain.

- 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 0.



Optional Properties:

- label: Human readable string with domain name. Will be visible in userspace

	to let user to distinguish between multiple domains in SoC.

- power-domains: phandle pointing to the parent power domain, for more details

		 see Documentation/devicetree/bindings/power/power_domain.txt



Deprecated Properties:

- clocks

- clock-names



Node of a device using power domains must have a power-domains property

defined with a phandle to respective power domain.



Example:



	lcd0: power-domain-lcd0 {

		compatible = "samsung,exynos4210-pd";

		reg = <0x10023C00 0x10>;

		#power-domain-cells = <0>;

		label = "LCD0";

	};



	mfc_pd: power-domain@10044060 {

		compatible = "samsung,exynos4210-pd";

		reg = <0x10044060 0x20>;

		#power-domain-cells = <0>;

		label = "MFC";

	};



See Documentation/devicetree/bindings/power/power_domain.txt for description

of consumer-side bindings.
