[PATCH v3 00/16] Implement H3/H5 HDMI driver

[Jernej Skrabec]

This series implements H3/H5 HDMI driver. It was tested on OrangePi 2 (H3),
OrangePi Plus2e (H3) and OrangePi PC2 (H5) with many resolutions and it
works well.

Code is based on linux-next, next-20180228 tag.

Best regards,
Jernej

Changes in v3:
- Removed TCON patch to skip LVDS procesing
- Added TCON patch to release exclusive clock lock
- Minimal clock rate is now returned immediately in round_rate for NM PLLs

Changes in v2:
- Fixed build warning on arm64
- Fixed condition in determine_rate function in HDMI PHY clock driver
- Added defines for polarity settings in HDMI PHY
- Added patch to skip LVDS code path altogether if TCON doesn't support it.
- round_rate for NM PLLs now rounds to minimal rate if requested rate is
  lower.
- set_rate for NM PLLs doesn't fail if requested rate is lower than minimal
  (round_rate is called before which already guarantees that rate is not
   lower than minimal).

Jernej Skrabec (16):
