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

Pull drm updates from Dave Airlie:
 "This is the main git pull for the drm,

  I pretty much froze major pulls at -rc5/6 time, and haven't had much
  fallout, so will probably continue doing that.

  Lots of changes all over, big internal header cleanup to make it clear
  drm features are legacy things and what are things that modern KMS
  drivers should be using.  Also big move to use the new generic fences
  in all the TTM drivers.

  core:
        atomic prep work,
        vblank rework changes, allows immediate vblank disables
        major header reworking and cleanups to better delinate legacy
        interfaces from what KMS drivers should be using.
        cursor planes locking fixes

  ttm:
        move to generic fences (affects all TTM drivers)
        ppc64 caching fixes

  radeon:
        userptr support,
        uvd for old asics,
        reset rework for fence changes
        better buffer placement changes,
        dpm feature enablement
        hdmi audio support fixes

  intel:
        Cherryview work,
        180 degree rotation,
        skylake prep work,
        execlist command submission
        full ppgtt prep work
        cursor improvements
        edid caching,
        vdd handling improvements

  nouveau:
        fence reworking
        kepler memory clock work
        gt21x clock work
        fan control improvements
        hdmi infoframe fixes
        DP audio

  ast:
        ppc64 fixes
        caching fix

  rcar:
        rcar-du DT support

  ipuv3:
        prep work for capture support

  msm:
        LVDS support for mdp4, new panel, gpu refactoring

  exynos:
        exynos3250 SoC support, drop bad mmap interface,
        mipi dsi changes, and component match support"
