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.
