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.... Improve warning message
- Move mxsfb patches to the end of the queue and the actual nwl fix to the front.
Changes from v2:
- Review comments by Lucas Stach https://lore.kernel.org/dri-devel/cover.1633332399.git.agx@sigxcpu.org/T/#m9... Drop fixes tag from mxsfb driver and tweak commit message
