Merge tag 'drm-for-v4.12' of git://people.freedesktop.org/~airlied/linux
Pull drm u pdates from Dave Airlie: "This is the main drm pull request for v4.12. Apart from two fixes pulls, everything should have been in drm-next for at least 2 weeks. The biggest thing in here is AMD released the public headers for their upcoming VEGA GPUs. These as always are quite a sizeable chunk of header files. They've also added initial non-display support for those GPUs, though they aren't available in production yet. Otherwise it's pretty much normal. New bridge drivers: - megachips-stdpxxxx-ge-b850v3-fw LVDS->DP++ - generic LVDS bridge support. Core: - Displayport link train failure reporting to userspace - debugfs interface cleaned up - subsystem TODO in kerneldoc now - Extended fbdev support (flipping and vblank wait) - drm_platform removed - EDP CRC support in helper - HF-VSDB SCDC support in EDID parser - Lots of code cleanups and header extraction - Thunderbolt external GPU awareness - Atomic helper improvements - Documentation improvements panel: - Sitronix and Samsung new panel support amdgpu: - Preliminary vega10 support - Multi-level page table support - GPU sensor support for userspace - PRT support for sparse buffers - SR-IOV improvements - Non-contig VRAM CPU mapping i915: - Atomic modesetting enabled by default on Gen5+ - LSPCON improvements - Atomic state handling for cdclk - GPU reset improvements - In-kernel unit tests - Geminilake improvements and color manager support - Designware i2c fixes - vblank evasion improvements - Hotplug safe connector iterators - GVT scheduler QoS support - GVT Kabylake support nouveau: - Acceleration support for Pascal (GP10x). - Rearchitecture of code handling proprietary signed firmware - Fix GTX 970 with odd MMU configuration - GP10B support - GP107 acceleration support vmwgfx: - Atomic modesetting support for vmwgfx omapdrm: - Support for render nodes - Refactor omapdss code - Fix some probe ordering issues - Fix too dark RGB565 rendering sunxi: - prelim rework for multiple pipes. mali-dp: - Color management support - Plane scaling - Power management improvements imx-drm: - Prefetch Resolve Engine/Gasket on i.MX6QP - Deferred plane disabling - Separate alpha support mediatek: - Mediatek SoC MT2701 support rcar-du: - Gen3 HDMI support msm: - 4k support for newer chips - OPP bindings for gpu - prep work for per-process pagetables vc4: - HDMI audio support - fixes qxl: - minor fixes. dw-hdmi: - PHY improvements - CSC fixes - Amlogic GX SoC support" * tag 'drm-for-v4.12' of git://people.freedesktop.org/~airlied/linux: (1778 commits) drm/nouveau/fb/gf100-: Fix 32 bit wraparound in new ram detection drm/nouveau/secboot/gm20b: fix the error return code in gm20b_secboot_tegra_read_wpr() drm/nouveau/kms: Increase max retries in scanout position queries. drm/nouveau/bios/bitP: check that table is long enough for optional pointers drm/nouveau/fifo/nv40: no ctxsw for pre-nv44 mpeg engine drm: mali-dp: use div_u64 for expensive 64-bit divisions drm/i915: Confirm the request is still active before adding it to the await drm/i915: Avoid busy-spinning on VLV_GLTC_PW_STATUS mmio drm/i915/selftests: Allocate inode/file dynamically drm/i915: Fix system hang with EI UP masked on Haswell drm/i915: checking for NULL instead of IS_ERR() in mock selftests drm/i915: Perform link quality check unconditionally during long pulse drm/i915: Fix use after free in lpe_audio_platdev_destroy() drm/i915: Use the right mapping_gfp_mask for final shmem allocation drm/i915: Make legacy cursor updates more unsynced drm/i915: Apply a cond_resched() to the saturated signaler drm/i915: Park the signaler before sleeping drm: mali-dp: Check the mclk rate and allow up/down scaling drm: mali-dp: Enable image enhancement when scaling drm: mali-dp: Add plane upscaling support ...
