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

Pull drm updates from Dave Airlie:
 "This is the main drm merge window pull request, changes all over the
  place, mostly normal levels of churn.

  Highlights:

  Core drm:
     More cleanups, fix race on connector/encoder naming, docs updates,
     object locking rework in prep for atomic modeset

  i915:
     mipi DSI support, valleyview power fixes, cursor size fixes,
     execlist refactoring, vblank improvements, userptr support, OOM
     handling improvements

  radeon:
     GPUVM tuning and large page size support, gart fixes, deep color
     HDMI support, HDMI audio cleanups

  nouveau:
     - displayport rework should fix lots of issues
     - initial gk20a support
     - gk110b support
     - gk208 fixes

  exynos:
     probe order fixes, HDMI changes, IPP consolidation

  msm:
     debugfs updates, misc fixes

  ast:
     ast2400 support, sync with UMS driver

  tegra:
     cleanups, hdmi + hw cursor for Tegra 124.

  panel:
     fixes existing panels add some new ones.

  ipuv3:
     moved from staging to drivers/gpu"
