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.
