Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "This is a combo of -next and some -fixes that came in in the intervening time. Highlights: New drivers: ARM Armada driver for Marvell Armada 510 SOCs Intel: Broadwell initial support under a default off switch, Stereo/3D HDMI mode support Valleyview improvements Displayport improvements Haswell fixes initial mipi dsi panel support CRC support for debugging build with CONFIG_FB=n Radeon: enable DPM on a number of GPUs by default secondary GPU powerdown support enable HDMI audio by default Hawaii support Nouveau: dynamic pm code infrastructure reworked, does nothing major yet GK208 modesetting support MSI fixes, on by default again PMPEG improvements pageflipping fixes GMA500: minnowboard SDVO support VMware: misc fixes MSM: prime, plane and rendernodes support Tegra: rearchitected to put the drm driver into the drm subsystem. HDMI and gr2d support for tegra 114 SoC QXL: oops fix, and multi-head fixes DRM core: sysfs lifetime fixes client capability ioctl further cleanups to device midlayer more vblank timestamp fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (789 commits) drm/nouveau: do not map evicted vram buffers in nouveau_bo_vma_add drm/nvc0-/gr: shift wrapping bug in nvc0_grctx_generate_r406800 drm/nouveau/pwr: fix missing mutex unlock in a failure path drm/nv40/therm: fix slowing down fan when pstate undefined drm/nv11-: synchronise flips to vblank, unless async flip requested drm/nvc0-: remove nasty fifo swmthd hack for flip completion method drm/nv10-: we no longer need to create nvsw object on user channels drm/nouveau: always queue flips relative to kernel channel activity drm/nouveau: there is no need to reserve/fence the new fb when flipping drm/nouveau: when bailing out of a pushbuf ioctl, do not remove previous fence drm/nouveau: allow nouveau_fence_ref() to be a noop drm/nvc8/mc: msi rearm is via the nvc0 method drm/ttm: Fix vma page_prot bit manipulation drm/vmwgfx: Fix a couple of compile / sparse warnings and errors drm/vmwgfx: Resource evict fixes drm/edid: compare actual vrefresh for all modes for quirks drm: shmob_drm: Convert to clk_prepare/unprepare drm/nouveau: fix 32-bit build drm/i915/opregion: fix build error on CONFIG_ACPI=n Revert "drm/radeon/audio: don't set speaker allocation on DCE4+" ...
