SAMSUNG S5P/Exynos SoC series System Registers (SYSREG)

Properties:

 - 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.

Example:

	syscon@10010000 {

		compatible = "samsung,exynos4-sysreg", "syscon";

		reg = <0x10010000 0x400>;

	};

	syscon@10050000 {

		compatible = "samsung,exynos5-sysreg", "syscon";

		reg = <0x10050000 0x5000>;

	};
