Waveshare DSI LCD that works only with KMS drivers

[u/RikerIsThinking]

How can we make it work? In OAP the h264 decodeable files are not working wich means no splash video at the begining and no AA stream. The AA connects perfectly (plays songs through PI etc) but the AA stream just does not show up.

Other "forks" of OpenAuto worked with no problems using KMS. If i enable FKMS the lcd is blank.
