I read through it all (well mostly the drm relevant bits, not your backend
code) and looks fairly resonable. Few minor clenaups and code removals
tbh.

Wrt merging/maintianing, do you want to maintain it as part of the
drm-misc small drivers group? Highly recommended imo. See

https://01.org/linuxgraphics/gfx-docs/maintainer-tools/drm-misc.html#small-drivers

for details. Ideally we'd need 2 xilinx maintainers to be able to push
patches & cross-review stuff.
