	  This adds driver for Exynos5422 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.

config EXYNOS_SROM
	bool "Exynos SROM controller driver" if COMPILE_TEST
	depends on (ARM && ARCH_EXYNOS) || (COMPILE_TEST && HAS_IOMEM)
	help
	  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.
