I like.

Reviewed some of the prep patches, plus some more suggestions for
drm_client_modeset api polishing ideas.

Maxime is working on some other fbdev helper features and your two patch
series will conflict badly I think. Probably best if you coordinate and
cross-review for final details and best coordination for merging into
drm-misc-next.

I think for the bootsplash good option would be to add it as a todo item,
with a link to patch of your latest proof of concept.

Cheers, Daniel
