Pull drm updates from Dave Airlie: "The biggest thing in this is the AMD Navi GPU support, this again contains a bunch of header files that are large. These are the new AMD RX5700 GPUs that just recently became available. New drivers: - ST-Ericsson MCDE driver - Ingenic JZ47xx SoC UAPI change: - HDR source metadata property Core: - HDR inforframes and EDID parsing - drm hdmi infoframe unpacking - remove prime sg_table caching into dma-buf - New gem vram helpers to reduce driver code - Lots of drmP.h removal - reservation fencing fix - documentation updates - drm_fb_helper_connector removed - mode name command handler rewrite fbcon: - Remove the fbcon notifiers ttm: - forward progress fixes dma-buf: - make mmap call optional - debugfs refcount fixes - dma-fence free with pending signals fix - each dma-buf gets an inode Panels: - Lots of additional panel bindings amdgpu: - initial navi10 support - avoid hw reset - HDR metadata support - new thermal sensors for vega asics - RAS fixes - use HMM rather than MMU notifier - xgmi topology via kfd - SR-IOV fixes - driver reload fixes - DC use a core bpc attribute - Aux fixes for DC - Bandwidth calc updates for DC - Clock handling refactor - kfd VEGAM support vmwgfx: - Coherent memory support changes i915: - HDR Support - HDMI i2c link - Icelake multi-segmented gamma support - GuC firmware update - Mule Creek Canyon PCH support for EHL - EHL platform updtes - move i915.alpha_support to i915.force_probe - runtime PM refactoring - VBT parsing refactoring - DSI fixes - struct mutex dependency reduction - GEM code reorg mali-dp: - Komeda driver features msm: - dsi vs EPROBE_DEFER fixes - msm8998 snapdragon 835 support - a540 gpu support - mdp5 and dpu interconnect support exynos: - drmP.h removal tegra: - misc fixes tda998x: - audio support improvements - pixel repeated mode support - quantisation range handling corrections - HDMI vendor info fix armada: - interlace support fix - overlay/video plane register handling refactor - add gamma support rockchip: - RX3328 support panfrost: - expose perf counters via hidden ioctls vkms: - enumerate CRC sources list ast: - rework BO handling mgag200: - rework BO handling dw-hdmi: - suspend/resume support rcar-du: - R8A774A1 Soc Support - LVDS dual-link mode support - Additional formats - Misc fixes omapdrm: - DSI command mode display support stm - fb modifier support - runtime PM support sun4i: - use vmap ops vc4: - binner bo binding rework v3d: - compute shader support - resync/sync fixes - job management refactoring lima: - NULL pointer in irq handler fix - scheduler default timeout virtio: - fence seqno support - trace events bochs: - misc fixes tc458767: - IRQ/HDP handling sii902x: - HDMI audio support atmel-hlcdc: - misc fixes meson: - zpos support" * tag 'drm-next-2019-07-16' of git://anongit.freedesktop.org/drm/drm: (1815 commits) Revert "Merge branch 'vmwgfx-next' of git://people.freedesktop.org/~thomash/linux into drm-next" Revert "mm: adjust apply_to_pfn_range interface for dropped token." mm: adjust apply_to_pfn_range interface for dropped token. drm/amdgpu/navi10: add uclk activity sensor drm/amdgpu: properly guard the generic discovery code drm/amdgpu: add missing documentation on new module parameters drm/amdgpu: don't invalidate caches in RELEASE_MEM, only do the writeback drm/amd/display: avoid 64-bit division drm/amdgpu/psp11: simplify the ucode register logic drm/amdgpu: properly guard DC support in navi code drm/amd/powerplay: vega20: fix uninitialized variable use drm/amd/display: dcn20: include linux/delay.h amdgpu: make pmu support optional drm/amd/powerplay: Zero initialize current_rpm in vega20_get_fan_speed_percent drm/amd/powerplay: Zero initialize freq in smu_v11_0_get_current_clk_freq drm/amd/powerplay: Use memset to initialize metrics structs drm/amdgpu/mes10.1: Fix header guard drm/amd/powerplay: add temperature sensor support for navi10 drm/amdgpu: fix scheduler timeout calc drm/amdgpu: Prepare for hmm_range_register API change (v2) ...
