+ This adds driver for Samsung Exynos5422 SoC DMC (Dynamic Memory
+ Controller). The driver provides support for Dynamic Voltage and
+ Frequency Scaling in DMC and DRAM. It also supports changing timings

+ This adds driver for Samsung Exynos SoC SROM controller. The driver

+ or external devices.
+ If unsure, say Y on devices with Samsung Exynos SoCs.
