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."
