Merge tag 'drm-for-v4.13' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "This is the main pull request for the drm, I think I've got one later driver pull for mediatek SoC driver, I'm undecided on if it needs to go to you yet. Otherwise summary below: Core drm: - Atomic add driver private objects - Deprecate preclose hook in modern drivers - MST bandwidth tracking - Use kvmalloc in more places - Add mode_valid hook for crtc/encoder/bridge - Reduce sync_file construction time - Documentation updates - New DRM synchronisation object support New drivers: - pl111 - pl111 CLCD display controller Panel: - Innolux P079ZCA panel driver - Add NL12880B20-05, NL192108AC18-02D, P320HVN03 panels - panel-samsung-s6e3ha2: Add s6e3hf2 panel support i915: - SKL+ watermark fixes - G4x/G33 reset improvements - DP AUX backlight improvements - Buffer based GuC/host communication - New getparam for (sub)slice infomation - Cannonlake and Coffeelake initial patches - Execbuf optimisations radeon/amdgpu: - Lots of Vega10 bug fixes - Preliminary raven support - KIQ support for compute rings - MEC queue management rework - DCE6 Audio support - SR-IOV improvements - Better radeon/amdgpu selection support nouveau: - HDMI stereoscopic support - Display code rework for >= GM20x GPUs msm: - GEM rework for fine-grained locking - Per-process pagetable work - HDMI fixes for Snapdragon 820. vc4: - Remove 256MB CMA limit from vc4 - Add out-fence support - Add support for cygnus - Get/set tiling ioctls support - Add T-format tiling support for scanout zte: - add VGA support. etnaviv: - Thermal throttle support for newer GPUs - Restore userspace buffer cache performance - dma-buf sync fix stm: - add stm32f429 display support exynos: - Rework vblank handling - Fixup sw-trigger code sun4i: - V3s display engine support - HDMI support for older SoCs - Preliminary work on dual-pipeline SoCs. rcar-du: - VSP work imx-drm: - Remove counter load enable from PRE - Double read/write reduction flag support tegra: - Documentation for the host1x and drm driver. - Lots of staging ioctl fixes due to grate project work. omapdrm: - dma-buf fence support - TILER rotation fixes" * tag 'drm-for-v4.13' of git://people.freedesktop.org/~airlied/linux: (1270 commits) drm: Remove unused drm_file parameter to drm_syncobj_replace_fence() drm/amd/powerplay: fix bug fail to remove sysfs when rmmod amdgpu. amdgpu: Set cik/si_support to 1 by default if radeon isn't built drm/amdgpu/gfx9: fix driver reload with KIQ drm/amdgpu/gfx8: fix driver reload with KIQ drm/amdgpu: Don't call amd_powerplay_destroy() if we don't have powerplay drm/ttm: Fix use-after-free in ttm_bo_clean_mm drm/amd/amdgpu: move get memory type function from early init to sw init drm/amdgpu/cgs: always set reference clock in mode_info drm/amdgpu: fix vblank_time when displays are off drm/amd/powerplay: power value format change for Vega10 drm/amdgpu/gfx9: support the amdgpu.disable_cu option drm/amd/powerplay: change PPSMC_MSG_GetCurrPkgPwr for Vega10 drm/amdgpu: Make amdgpu_cs_parser_init static (v2) drm/amdgpu/cs: fix a typo in a comment drm/amdgpu: Fix the exported always on CU bitmap drm/amdgpu/gfx9: gfx_v9_0_enable_gfx_static_mg_power_gating() can be static drm/amdgpu/psp: upper_32_bits/lower_32_bits for address setup drm/amd/powerplay/cz: print message if smc message fails drm/amdgpu: fix typo in amdgpu_debugfs_test_ib_init ...
