Merge branch 'drm-next-4.15-dc' of git://people.freedesktop.org/~agd5f/linux into drm-next
Initial pull request for DC support. We've completed a substantial amount of
the cleanup and restructuring in our TODO. There are a few additional
cleanups that we are continuing to work on, but I don't think there are any
showstoppers remaining. We've tried to maintain most of the history for bisect
purposes. Harry made sure all the commits build. We've enabled DC for vega10
and Raven. Pre-vega10 parts can be enabled via module parameter (amdgpu.dc=1),
but are not enabled by default at this point until we get further testing
upstream.
This code provides atomic modesetting support for DCE8 (CIK), DCE10 (Tonga,
Fiji), DCE11 (CZ, ST, Polaris), DCE12 (vega10), and DCN1 (RV) including
HDMI and DP audio, DP MST, and many other advanced display features.
+
Latest cleanups for DC from you and Harry. Note that there is some
flickering on some older asics with this branch due to a regression in powerplay
that has already been fixed and will be included in my next non-DC pull request
next week.
