Should you ever need a DisplayPort reference for NXPs imx8mq: here's a hardware mod for the #Librem5 Devkit to switch it from #HDMI to #DisplayPort: https://source.puri.sm/guido.gunther/imx8mq-hdmi2dp (based on schematic by Bernhard Fink in NXPs forums).

@agx, Another thing that I noticed was that the i.MX 8M Plus only supports HDMI and no DisplayPort.
If the Plus requires a binary blob for HDMI like the Quad did, then it seems like the only solution for Fir is to add a chip to convert the LVDS output into DisplayPort, but it probably won't be as high of resolution as the Plus's HDMI.
Does the mainline Linux driver support LVDS on the i.MX 8M?
