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

Pull drm updates from Dave Airlie:
 "This is the main pull request for the drm for 4.3.  Nouveau is
  probably the biggest amount of changes in here, since it missed 4.2.
  Highlights below, along with the usual bunch of fixes.

  All stuff outside drm should have applicable acks.

  Highlights:

   - new drivers:
        freescale dcu kms driver

   - core:
        more atomic fixes
        disable some dri1 interfaces on kms drivers
        drop fb panic handling, this was just getting more broken, as more locking was required.
        new core fbdev Kconfig support - instead of each driver enable/disabling it
        struct_mutex cleanups

   - panel:
        more new panels
        cleanup Kconfig

   - i915:
        Skylake support enabled by default
        legacy modesetting using atomic infrastructure
        Skylake fixes
        GEN9 workarounds

   - amdgpu:
        Fiji support
        CGS support for amdgpu
        Initial GPU scheduler - off by default
        Lots of bug fixes and optimisations.

   - radeon:
        DP fixes
        misc fixes

   - amdkfd:
        Add Carrizo support for amdkfd using amdgpu.

   - nouveau:
        long pending cleanup to complete driver,
        fully bisectable which makes it larger,
        perfmon work
        more reclocking improvements
        maxwell displayport fixes

   - vmwgfx:
        new DX device support, supports OpenGL 3.3
        screen targets support

   - mgag200:
        G200eW support
        G200e new revision support

   - msm:
        dragonboard 410c support, msm8x94 support, msm8x74v1 support
        yuv format support
        dma plane support
        mdp5 rotation
        initial hdcp

   - sti:
        atomic support

   - exynos:
        lots of cleanups
        atomic modesetting/pageflipping support
        render node support

   - tegra:
        tegra210 support (dc, dsi, dp/hdmi)
        dpms with atomic modesetting support

   - atmel:
        support for 3 more atmel SoCs
        new input formats, PRIME support.

   - dwhdmi:
        preparing to add audio support

   - rockchip:
        yuv plane support"
