Help text

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 of DRAM running with different frequency. The timings are calculated based on DT memory information. If unsure, say Y on devices with Samsung Exynos SoCs.
