I think we have at least three or four potential target trees for this:
driver-core (I/O), drm-rust (Nova), bitmap / Rust.

(I don't know which tree the bitmap stuff would go through, I did not find =
a
tree entry in the MAINTAINERS file.)

Unless someone thinks otherwise, I'd take it through the drm-rust tree once=
 the
series is ready. This should cause the least conflicts and as a bonus enabl=
e Tyr
to use it right away.
