The downstream driver will not be acceptable to mainline. It's not just
the size of the driver itself, but it's just full of cruft and doesn't
integrate with any of the modern kernel frameworks.

If you are going to mainline this driver, it likely needs a full
rewrite as a proper DRM driver, with a userspace interface sanctioned
by the Linux DRM community.
