+* 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:
+- compatiable: should be one of the following.
+ * samsung,exynos4210-pd - for exynos4210 type power domain.
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+Optional Properties:
+- samsung,exynos4210-pd-off: Specifies that the power domain is in turned-off
+ state during boot and remains to be turned-off until explicitly turned-on.
+
+Example:
+
+ lcd0: power-domain-lcd0 {
+ compatible = "samsung,exynos4210-pd";
+ reg = <0x10023C00 0x10>;
+ };
