Looking at this patch series, feels a bit like hand-rolling of bridge
code, badly. We should get away from that.

Once you have that I think the end result is tiny enough that it can
stay, bridges intergrate quite well into simple display pipe drivers.

Simplest is if this can all land through drm-misc, is arc not
maintained in there? And there's plenty of time for testing, I'm just
slowly crawling through the tree to get everything polished and
cleaned up in this area.
