 SAMSUNG S5P/Exynos SoC series System Registers (SYSREG)
 
 Properties:
- - name : should be 'sysreg';
  - compatible : should contain "samsung,<chip name>-sysreg", "syscon";
    For Exynos4 SoC series it should be "samsung,exynos4-sysreg", "syscon";
  - reg : offset and length of the register set.
