This series adds support for the HDMI-TX v2 Encoder and DDCv2, as found
in MT8195, MT8188 and their variants.
Tested on Genio 700 EVK:
- ABIST ON: ok, pattern generated internally from HDMI is shown on
HDMI screen at the correct resolution;
- ABIST OFF + DPI Pattern Generator ON: ok, pattern coming from DPI is
shown on HDMI screen at the correct resolution;
- Can negotiate up to 4k60
and on MT8395 Radxa NIO 12L:
- ABIST ON: ok, pattern generated internally from HDMI is shown on
HDMI screen at the correct resolution;
- ABIST OFF + DPI Pattern Generator ON: ok, pattern coming from DPI is
shown on HDMI screen at the correct resolution;
- Dual screen usecase validated (DSI + HDMI 3840x2160p 60Hz)
- Can negotiate up to 4k60
Please note that this submission does *not* include support for HDCP
nor for CECv2, as I want this to be upstream before implementing
additional features which are not strictly required for simple
HDMI output.
