[RFC,0/5] drm/mediatek: Add mt8195 DisplayPort driver

Hi everyone,

this series is built around the DisplayPort driver. The dpi/dpintf driver and
the added helper functions are required for the DisplayPort.

Note that this is an RFC. I would like to have your opinion on the driver and
what needs to change. The driver itself has its rough edges that I am currently
still working on, especially the training and powerup/down need some work in
my opinion. Also the code compiles without an issue but is not fully tested
yet.

However I already wanted to reach out for some feedback to see what can and
should be improved. I am happy about every comment, thanks for taking the
time.

The series is currently based on v5.14-rc5 but it requires other patches to
actually work on mt8195 (clock, etc.). A binding documentation is not included
yet.

Thanks,
Markus
