- compatible : should contain two values. First value must be one from following list:
+ - "samsung,exynos4210-pmu" - for Exynos4210 SoC,
+ - "samsung,exynos4212-pmu" - for Exynos4212 SoC,
+ - "samsung,exynos4412-pmu" - for Exynos4412 SoC,
- "samsung,exynos5250-pmu" - for Exynos5250 SoC,
- "samsung,exynos5420-pmu" - for Exynos5420 SoC.
second value must be always "syscon".
