Subject: [PATCH v2 0/5] mxsfb/nwl/panels: media bus format fixes
Date: Mon, 4 Oct 2021 09:27:33 +0200 [thread overview]
Message-ID: <cover.1633332399.git.agx@sigxcpu.org> (raw)
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.
All patches of this series can be applied independently.
Changes from v1:
- Review comment by Marek Vasut
https://lore.kernel.org/dri-devel/67e6056a-6157-795d-908d-d65cc803c03d@denx.de/
Improve warning message
- Move mxsfb patches to the end of the queue and the actual nwl fix to the
front.
