Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "Okay this is the big one, I was stalled on the fbdev pull req as I stupidly let fbdev guys merge a patch I required to fix a warning with some patches I had, they ended up merging the patch from the wrong place, but the warning should be fixed. In future I'll just take the patch myself! Outside drm: There are some snd changes for the HDMI audio interactions on haswell, they've been acked for inclusion via my tree. This relies on the wound/wait tree from Ingo which is already merged. Major changes: AMD finally released the dynamic power management code for all their GPUs from r600->present day, this is great, off by default for now but also a huge amount of code, in fact it is most of this pull request. Since it landed there has been a lot of community testing and Alex has sent a lot of fixes for any bugs found so far. I suspect radeon might now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable dynamic powermanagement for anyone. New drivers: Renesas r-car display unit. Other highlights: - core: GEM CMA prime support, use new w/w mutexs for TTM reservations, cursor hotspot, doc updates - dvo chips: chrontel 7010B support - i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell), Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp support (this time for sure) - nouveau: async buffer object deletion, context/register init updates, kernel vp2 engine support, GF117 support, GK110 accel support (with external nvidia ucode), context cleanups. - exynos: memory leak fixes, Add S3C64XX SoC series support, device tree updates, common clock framework support, - qxl: cursor hotspot support, multi-monitor support, suspend/resume support - mgag200: hw cursor support, g200 mode limiting - shmobile: prime support - tegra: fixes mostly I've been banging on this quite a lot due to the size of it, and it seems to okay on everything I've tested it on." * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (811 commits) drm/radeon/dpm: implement vblank_too_short callback for si drm/radeon/dpm: implement vblank_too_short callback for cayman drm/radeon/dpm: implement vblank_too_short callback for btc drm/radeon/dpm: implement vblank_too_short callback for evergreen drm/radeon/dpm: implement vblank_too_short callback for 7xx drm/radeon/dpm: add checks against vblank time drm/radeon/dpm: add helper to calculate vblank time drm/radeon: remove stray line in old pm code drm/radeon/dpm: fix display_gap programming on rv7xx drm/nvc0/gr: fix gpc firmware regression drm/nouveau: fix minor thinko causing bo moves to not be async on kepler drm/radeon/dpm: implement force performance level for TN drm/radeon/dpm: implement force performance level for ON/LN drm/radeon/dpm: implement force performance level for SI drm/radeon/dpm: implement force performance level for cayman drm/radeon/dpm: implement force performance levels for 7xx/eg/btc drm/radeon/dpm: add infrastructure to force performance levels drm/radeon: fix surface setup on r1xx drm/radeon: add support for 3d perf states on older asics drm/radeon: set default clocks for SI when DPM is disabled ...
