+	  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

+	  This adds driver for Samsung Exynos SoC SROM controller.  The driver
+	  in basic operation mode only saves and restores SROM registers
+	  during suspend.  If however appropriate device tree configuration
+	  is provided, the driver enables support for external memory
+	  or external devices.
+	  If unsure, say Y on devices with Samsung Exynos SoCs.
