Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "Been a bit busy, first week of kids school, and waiting on other trees to go in before I could send this, so its a bit later than I'd normally like. Highlights: - core: timestamp fixes, lots of misc cleanups - new drivers: bochs virtual vga - vmwgfx: major overhaul for their nextgen virt gpu. - i915: runtime D3 on HSW, watermark fixes, power well work, fbc fixes, bdw is no longer prelim. - nouveau: gk110/208 acceleration, more pm groundwork, old overlay support - radeon: dpm rework and clockgating for CIK, pci config reset, big endian fixes - tegra: panel support and DSI support, build as module, prime. - armada, omap, gma500, rcar, exynos, mgag200, cirrus, ast: fixes - msm: hdmi support for mdp5" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (595 commits) drm/nouveau: resume display if any later suspend bits fail drm/nouveau: fix lock unbalance in nouveau_crtc_page_flip drm/nouveau: implement hooks for needed for drm vblank timestamping support drm/nouveau/disp: add a method to fetch info needed by drm vblank timestamping drm/nv50: fill in crtc mode struct members from crtc_mode_fixup drm/radeon/dce8: workaround for atom BlankCrtc table drm/radeon/DCE4+: clear bios scratch dpms bit (v2) drm/radeon: set si_notify_smc_display_change properly drm/radeon: fix DAC interrupt handling on DCE5+ drm/radeon: clean up active vram sizing drm/radeon: skip async dma init on r6xx drm/radeon/runpm: don't runtime suspend non-PX cards drm/radeon: add ring to fence trace functions drm/radeon: add missing trace point drm/radeon: fix VMID use tracking drm: ast,cirrus,mgag200: use drm_can_sleep drm/gma500: Lock struct_mutex around cursor updates drm/i915: Fix the offset issue for the stolen GEM objects DRM: armada: fix missing DRM_KMS_FB_HELPER select drm/i915: Decouple GPU error reporting from ring initialisation ...
