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

Pull drm updates from Dave Airlie:
 "Highlights:

  Core:
   - Virtual GEM layer merged, this has been around for a long time, and
     it provides a software backed device that allows userspace to use
     it as a GEM shared memory handler.  This makes it a lot easier to
     do certain things when you have no GPU but still have to deal with
     DRI expectations.
   - atomic helper updates.
   - framebuffer modifier interface added.
   - i2c over auxch displayport fixes.
   - fb width/height confusion fixes.
   - new driver for ps8622/ps8625 bridge chips
   - lots of new panels

  i915:
   - more plane atomic conversion
   - vGPU guest support for XenGT
   - Skylake workarounds and fixes
   - Y-tiling support
   - work on dynamic pagetable allocation
   - EU count report param for gen9+
   - CHV fixes (no longer prelim)
   - remove ilk rc6
   - frontbuffer tracking for fbc
   - Displayport link rate refactoring
   - sprite colorkey refactor

  radeon:
   - Displayport MST support (not enabled by default)
   - non-ATOM native hw auxch support (DCE5+)
   - output csc support
   - new queries for userspace debug support
   - new VCE packet

  nouveau:
   - gk20a iommu support
   - gm107 graphics support
   - more gm20x bringup (waiting on signed nvidia fw).

  amdkfd:
   - multiple kgd instance support
   - use 64-bit time accessors

  msm:
   - stolen memory support
   - DSI and dual-DSI support
   - snapdragon 410 support

  exynos:
   - cleanups for atomic and pageflip

  imx-drm:
   - more media-bus formats
   - TV output prep
   - drm panel support

  tegra:
   - hw vblank counter using host1x syncpoints

  omap:
   - universal plane support
   - prep work for atomic modesetting

  rcar-du:
   - ported to atomic modesetting

  atmel-hlcdc:
   - ported to atomic modesetting
   - added suspend/resume support

  sti:
   - ported to atomic modesetting

  dwhdmi:
   - more compliant audio support
   - update rockchip phy support

  tda998x:
   - DT probing for attached crtcs
   - simplified EDID reading

  rockchip:
   - fixes

  adv7511:
   - fixes"
