I have pulled all the latest patches, including Marek's off-list patches together in one branch based on v5.10-rc7  if anyone is interested. I added some fixes on top, that I needed to get my display behind another Toshiba DSI-DPI bridge working. Those are probably not upstreamable at all and need further investigation. I'm hoping to reply to the individual threads for more feedback. I see that there are some blocking issues, but we hopefully get them resolved somehow. Thanks Frieder  https://github.com/fschrempf/linux/commits/v5.10-mx8mm-graphics
