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" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (1369 commits) drm/amdgpu: rename gmc_v8_0_init_compute_vmid drm/amdgpu: fix vce3 instance handling drm/amdgpu: remove ib test for the second VCE Ring drm/amdgpu: properly enable VM fault interrupts drm/amdgpu: fix warning in scheduler drm/amdgpu: fix buffer placement under memory pressure drm/amdgpu/cz: fix cz_dpm_update_low_memory_pstate logic drm/amdgpu: fix typo in dce11 watermark setup drm/amdgpu: fix typo in dce10 watermark setup drm/amdgpu: use top down allocation for non-CPU accessible vram drm/amdgpu: be explicit about cpu vram access for driver BOs (v2) drm/amdgpu: set MEC doorbell range for Fiji drm/amdgpu: implement burst NOP for SDMA drm/amdgpu: add insert_nop ring func and default implementation drm/amdgpu: add amdgpu_get_sdma_instance helper function drm/amdgpu: add AMDGPU_MAX_SDMA_INSTANCES drm/amdgpu: add burst_nop flag for sdma drm/amdgpu: add count field for the SDMA NOP packet v2 drm/amdgpu: use PT for VM sync on unmap drm/amdgpu: make wait_event uninterruptible in push_job ...
