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>;
};
