0017 This adds driver for Samsung Exynos5422 SoC DMC (Dynamic Memory
0018 Controller). The driver provides support for Dynamic Voltage and
0019 Frequency Scaling in DMC and DRAM. It also supports changing timings
0020 of DRAM running with different frequency. The timings are calculated
0021 based on DT memory information.

0028 This adds driver for Samsung Exynos SoC SROM controller. The driver
0029 in basic operation mode only saves and restores SROM registers
0030 during suspend. If however appropriate device tree configuration
0031 is provided, the driver enables support for external memory
0032 or external devices.
