Subject: [PATCH v3 0/5] mediatek: hdmi: add MT8167 configuration

The MT8167 SoC have a hard limit on the maximal supported HDMI TMDS clock,
and is not validated and supported for HDMI modes out of HDMI CEA modes.

To achieve this:
- switch the mediatek HDMI bindings to YAML
- add the MT8167 compatible
- add a boolean to discard the non-CEA modes
- add a value to specify mac TMDS supported clock
- add a conf entry for the MT8167 compatible

Changes since v4:
- fixed bindings

Neil Armstrong (5):
  dt-bindings: display: mediatek,hdmi: Convert to use graph schema
  dt-bindings: mediatek: add mt8167 to hdmi, hdmi-ddc and cec bindings
  gpu/drm: mediatek: hdmi: add check for CEA modes only
  gpu/drm: mediatek: hdmi: add optional limit on maximal HDMI mode clock
  gpu/drm: mediatek: hdmi: add MT8167 configuration
