17	  This adds driver for Exynos5422 DMC (Dynamic Memory Controller).
18	  The driver provides support for Dynamic Voltage and Frequency Scaling in
19	  DMC and DRAM. It also supports changing timings of DRAM running with
20	  different frequency. The timings are calculated based on DT memory
21	  information.

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