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).
@amosbatto #imx8mq CSI2 for mainliine is still being worked on (as is mhdp for DisplayPort HDMI) by various parties but the diff has become more and more reasonable.
