Changes since v2:
1. Use new name of file in samsung,sysmmu.yaml and MAINTAINERS.
Changes since v1:
1. Indent example with four spaces (more readable),
2. Remove unneeded types,
3. Add missing address in example and fix the name.

-* 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@...44060 {
- 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.
