From: Younggun Jang <yg1004.jang@xxxxxxxxxxx> This driver is mainly used for setting misc bits of register from PMU IP of Exynos SoC which will be required to configure before Suspend/Resume. Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC support, there is a need of DT based implementation of PMU driver. This driver uses already existing DT binding information.
