+SAMSUNG Exynos SoC series PMU Registers
+
+Properties:
+ - name : should be 'syscon';
+ - 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_syscon: syscon@10040000 {
+ compatible = "samsung,exynos5250-pmu", "syscon";
+ reg = <0x10040000 0x5000>;
