SAMSUNG Exynos SoC series PMU Registers



Properties:

 - compatible : should contain two values. First value must be one from following list:

		   - "samsung,exynos5250-pmu" - for Exynos5250 SoC,

		   - "samsung,exynos5420-pmu" - for Exynos5420 SoC.

		second value must be always "syscon".



 - reg : offset and length of the register set.



Example :

pmu_system_controller: system-controller@10040000 {

	compatible = "samsung,exynos5250-pmu", "syscon";

	reg = <0x10040000 0x5000>;

};
