+ 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.
