Subject[RFC 00/11] drm/bridge: dw-hdmi: implement bus-format negotiation and YUV420 support
Date
This patchset is based on Boris's "drm: Add support for bus-format negotiation" RFC at [1]
patchset to implement :
- basic bus-format negotiation for DW-HDMI
- advanced HDMI2.0 YUV420 bus-format negotiation for DW-HDMI

And the counterpart implementation in the Amlogic Meson VPU dw-hdmi glue :
- basic bus-format negotiation to select YUV444 bus-format as DW-HDMI input
- YUV420 support when HDMI2.0 YUV420 modeset

This is a follow-up from the previous attempts :
- "drm/meson: Add support for HDMI2.0 YUV420 4k60" at [2]
- "drm/meson: Add support for HDMI2.0 4k60" at [3]
