We have a bunch of changes queued up which will go usptream for 4.16.
See amd-staging-drm-next:
https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next
which is a mirror of our main development branch or:
https://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.16-wip
which is what is currently queued for 4.16.
