I know Dan MacDonald was reporting the same issue, and he was using my
driver.  We never got to the bottom of Dan's issue though, and I tried
suggesting disabling the other outputs.

Lukas' dt files only have HDMI output, so much like the SR Hummingboard
setup - but that seems to work fine (although I don't have any iMX6QP
devices, only iMX6S, D, Q and possibly a DL.)
