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.

If unsure, say Y on devices with Samsung Exynos SoCs.

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.
