commit b776b0f00f24 ("drm: mxsfb: Use bus_format from the nearest bridge if
present") added bus format probing to mxsfb this exposed several issues in the
display stack as used on the Librem 5:

The nwl bridge and the panels didn't bother to set any media bus formats and in
that case mxsfb would not pick a reasonable default. This series aims to fix
this.

This series includes the patch from
https://lore.kernel.org/dri-devel/YVLYh%2FSgBritG%2FRJ@qwark.sigxcpu.org/
with a `dev_warn` added.

The patches are against 5.15-rc3. I've marked a single patch with a 'fixes'
which is enough to unbreak the display stack in 5.15.
