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. |

|
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. |
