| This adds driver for Samsung Exynos5422 SoC 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. |

| 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 |
