FIFO underruns are seen if a AXI bus master with a higher priority do a

Uh, this fell through the cracks, sorry.
Can you please collect my RB, add:
Fixes: 9db35bb349a0 ("drm: lcdif: Add support for i.MX8MP LCDIF variant")
and send V2 ?
btw. the Panic mode seems to work on this IP with 4k displays and HDMI.
Sounds interesting, how did you verified that?
I plugged in a 4k panel into MX8MP HDMI port and saw this flicker, with
the panic regs programmed correctly, there is no more flicker, see the
commit messages of patch I posted yesterday for details, you were on CC:
[PATCH] drm: lcdif: Set and enable FIFO Panic threshold
