Support for the Memory Controller (MC) devices found on
Samsung Exynos SoCs.

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.
