Merge tag 'drm-for-v4.17' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "Cannonlake and Vega12 support are probably the two major things. This pull lacks nouveau, Ben had some unforseen leave and a few other blockers so we'll see how things look or maybe leave it for this merge window. core: - Device links to handle sound/gpu pm dependency - Color encoding/range properties - Plane clipping into plane check helper - Backlight helpers - DP TP4 + HBR3 helper support amdgpu: - Vega12 support - Enable DC by default on all supported GPUs - Powerplay restructuring and cleanup - DC bandwidth calc updates - DC backlight on pre-DCE11 - TTM backing store dropping support - SR-IOV fixes - Adding "wattman" like functionality - DC crc support - Improved DC dual-link handling amdkfd: - GPUVM support for dGPU - KFD events for dGPU - Enable PCIe atomics for dGPUs - HSA process eviction support - Live-lock fixes for process eviction - VM page table allocation fix for large-bar systems panel: - Raydium RM68200 - AUO G104SN02 V2 - KEO TX31D200VM0BAA - ARM Versatile panels i915: - Cannonlake support enabled - AUX-F port support added - Icelake base enabling until internal milestone of forcewake support - Query uAPI interface (used for GPU topology information currently) - Compressed framebuffer support for sprites - kmem cache shrinking when GPU is idle - Avoid boosting GPU when waited item is being processed already - Avoid retraining LSPCON link unnecessarily - Decrease request signaling latency - Deprecation of I915_SET_COLORKEY_NONE - Kerneldoc and compiler warning cleanup for upcoming CI enforcements - Full range ycbcr toggling - HDCP support i915/gvt: - Big refactor for shadow ppgtt - KBL context save/restore via LRI cmd (Weinan) - Properly unmap dma for guest page (Changbin) vmwgfx: - Lots of various improvements etnaviv: - Use the drm gpu scheduler - prep work for GC7000L support vc4: - fix alpha blending - Expose perf counters to userspace pl111: - Bandwidth checking/limiting - Versatile panel support sun4i: - A83T HDMI support - A80 support - YUV plane support - H3/H5 HDMI support omapdrm: - HPD support for DVI connector - remove lots of static variables msm: - DSI updates from 10nm / SDM845 - fix for race condition with a3xx/a4xx fence completion irq - some refactoring/prep work for eventual a6xx support (ie. when we have a userspace) - a5xx debugfs enhancements - some mdp5 fixes/cleanups to prepare for eventually merging writeback - support (ie. when we have a userspace) tegra: - mmap() fixes for fbdev devices - Overlay plane for hw cursor fix - dma-buf cache maintenance support mali-dp: - YUV->RGB conversion support rockchip: - rk3399/chromebook fixes and improvements rcar-du: - LVDS support move to drm bridge - DT bindings for R8A77995 - Driver/DT support for R8A77970 tilcdc: - DRM panel support" * tag 'drm-for-v4.17' of git://people.freedesktop.org/~airlied/linux: (1646 commits) drm/i915: Fix hibernation with ACPI S0 target state drm/i915/execlists: Use a locked clear_bit() for synchronisation with interrupt drm/i915: Specify which engines to reset following semaphore/event lockups drm/i915/dp: Write to SET_POWER dpcd to enable MST hub. drm/amdkfd: Use ordered workqueue to restore processes drm/amdgpu: Fix acquiring VM on large-BAR systems drm/amd/pp: clean header file hwmgr.h drm/amd/pp: use mlck_table.count for array loop index limit drm: Fix uabi regression by allowing garbage mode->type from userspace drm/amdgpu: Add an ATPX quirk for hybrid laptop drm/amdgpu: fix spelling mistake: "asssert" -> "assert" drm/amd/pp: Add new asic support in pp_psm.c drm/amd/pp: Clean up powerplay code on Vega12 drm/amd/pp: Add smu irq handlers for legacy asics drm/amd/pp: Fix set wrong temperature range on smu7 drm/amdgpu: Don't change preferred domian when fallback GTT v5 drm/vmwgfx: Bump version patchlevel and date drm/vmwgfx: use monotonic event timestamps drm/vmwgfx: Unpin the screen object backup buffer when not used drm/vmwgfx: Stricter count of legacy surface device resources ...
