Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

Pull drm tree changes from Dave Airlie:
 "This is the main drm pull request, I have some overlap with sound and
  arm-soc, the sound patch is acked and may conflict based on -next
  reports but should be a trivial fixup, which I'll leave to you!

  Highlights:

   - new drivers:

     MSM driver from Rob Clark

   - non-drm:

     switcheroo and hdmi audio driver support for secondary GPU
     poweroff, so drivers can use runtime PM to poweroff the GPUs.  This
     can save 5 or 6W on some optimus laptops.

   - drm core:

     combined GEM and TTM VMA manager
     per-filp mmap permission tracking
     initial rendernode support (via a runtime enable for now, until we get api stable),
     remove old proc support,
     lots of cleanups of legacy code
     hdmi vendor infoframes and 4k modes
     lots of gem/prime locking and races fixes
     async pageflip scaffolding
     drm bridge objects

   - i915:

     Haswell PC8+ support and eLLC support, HDMI 4K support, initial
     per-process VMA pieces, watermark reworks, convert to generic hdmi
     infoframes, encoder reworking, fastboot support,

   - radeon:

     CIK PM support, remove 3d blit code in favour of DMA engines,
     Berlin GPU support, HDMI audio fixes

   - nouveau:

     secondary GPU power down support for optimus laptops, lots of
     fixes, use MSI, VP3 engine support

   - exynos:

     runtime pm support for g2d, DT support, remove non-DT,

   - tda998x i2c driver:

     lots of fixes for sync issues

   - gma500:

     lots of cleanups

   - rcar:

     add LVDS support, fbdev emulation,

   - tegra:

     just minor fixes"
