I think nowadays pretty much all the cross-driver work lands through
drm-misc. Exception is just new stuff that's only used by a single driver.

For testing there's also drm-tip, which tries to pull it all together (but
you might still want to point your CI at branches).

Also note that drm-misc-next doesn't have a merge window freeze period
(with have the drm-misc-next-fixes branch during that time for merge
window fixes), so you can treat it like a main development branch like
e.g. in mesa, with the -fixes branches as the release branches. Only
difference is that we don't cherry pick patches from the main branch to
the release branches (at least not as the normal flow).

If you do need a backmerge for patches from Linus to drm-misc-next because
of some feature work (or conflicts with other stuff in general) drm-misc
maintainers do that. Usually happens every few weeks.
