[PATCH v3 0/3] Add hs400 support for rk3399 and rk3568

[Yifeng Zhao]

RK3399 and RK3568 are use different sdhci controllers.
The drivers need to be updated to support these two platforms
and it's easy to support new platforms.


Changes in v3:
- Optimize hs200 tuning function.
- Add check for callback function.
- Add return value for tuning function.
- Fixed source clock rate with host->max_clk, the interface clock is divided
  from the source clock.
- Config the interface clock by clk_set_rate directly
- Enable SDMA.

Changes in v2:
- Add mmc_of_parse to parse dts config.
- Used read_poll_timeout api to check dll lock status
- Add execute tuning api for hs200 tuning
- Used sdhci_set_clock api to set clock.
- Used read_poll_timeout api to check dll status.
