SAMSUNG S5P/Exynos SoC series System Registers (SYSREG)
Properties:
- compatible : should contain "samsung,<chip name>-sysreg", "syscon";
For Exynos4 SoC series it should be "samsung,exynos4-sysreg", "syscon";
- compatible : should contain two values. First value must be one from following list:
- "samsung,exynos4-sysreg" - for Exynos4 based SoCs,
- "samsung,exynos5-sysreg" - for Exynos5 based SoCs.
second value must be always "syscon".
- reg : offset and length of the register set.
