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
