SAMSUNG S5P/Exynos SoC series System Registers (SYSREG)





Properties:

Properties:

 - compatible : should contain "samsung,<chip name>-sysreg", "syscon";

 - compatible : should contain two values. First value must be one from following list:

   For Exynos4 SoC series it should be "samsung,exynos4-sysreg", "syscon";

		- "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.
