From: Guido Günther
Date: Tue Sep 28 2021 - 08:16:34 EST

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 series includes the patch from
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.

Guido Günther (5):
drm: mxsfb: Print failed bus format in hex
drm: mxsfb: Set proper default bus format when using a bridge
drm/bridge: nwl-dsi: Add atomic_get_input_bus_fmts
drm/panel: mantix: Add media bus format
drm/panel: st7703: Add media bus format
