This patch adds device tree node for the SYSREG registers block found in Samsung S5P/Exynos SoC series. The SYSREG module generates control signals for the ARM CPU and various IP blocks and buses. SYSREG block registers are exposed through APB bus interface. A sysreg device tree node is to be associated with mfd syscon driver and all SYSREG clients should use regmap interface it provides. It allows to eliminate any possible races and conflicts should different drivers attempt to concurrently access same register.
