Yes, MIPI_DSI_MODE_VIDEO was indeed missing/wrongly applied and some
more bugs. But I still wasn't able to make it work.

I also tried to fake the panel-orisetech-otm8009a.c DSI driver into
my setup. It should not properly program the panel by DCS command
but it should try to.

Result is the same: I can see it being probed and calling get_modes
but then:

[drm] Cannot find any crtc or sizes

And I don't see calls to .enable or .prepare where DCS commands would
be sent.

BR and thanks,
Nikolaus
