Subject: [PATCH v1] memory: mediatek: add DRAM controller driver
These patch series introduces the MediaTek DRAM controller driver (DRAMC)
on MT6779 SoC, and enables to be built as a module by default for the
ARM64 builds.
MediaTek DRAMC driver provides cross-platform features as below:
- API provided to other kernel modules for querying DRAM type,
rank count, rank size, channel count and mode register settings.
- Sysfs interface used to pass DRAM mode register settings and current
DRAM data rate to user-space for MediaTek ecosystem.
The API user includes MediaTek External Memory Interface (EMI) and
DVFS Resource Control (DVFSRC), which will be sent to mainline later.
