+SAMSUNG Exynos SoC series PMU Registers
+
+Properties:
+ - name : should be 'syscon';
+ - compatible : should contain samsung,chip name-pmu, syscon;
+ For Exynos5250 SoC it should be samsung,exynos5250-pmu, syscon;
+ - reg : offset and length of the register set.
+
+Example :
+pmu_syscon: syscon@1004 {
+ compatible = samsung,exynos5250-pmu, syscon;
+ reg = 0x1004 0x5000;
+};
