Pull drm updates from Dave Airlie:
"This is going to rebuild more than drm as it adds a new helper to
list.h for doing bulk updates. Seemed like a reasonable addition to
me.
Otherwise the usual merge window stuff lots of i915 and amdgpu, not so
much nouveau, and piles of everything else.
Core:
- Adds a new list.h helper for doing bulk list updates for TTM.
- Don't leak fb address in smem_start to userspace (comes with EXPORT
workaround for people using mali out of tree hacks)
- udmabuf device to turn memfd regions into dma-buf
- Per-plane blend mode property
- ref/unref replacements with get/put
- fbdev conflicting framebuffers code cleaned up
- host-endian format variants
- panel orientation quirk for Acer One 10
bridge:
- TI SN65DSI86 chip support
vkms:
- GEM support.
- Cursor support
amdgpu:
- Merge amdkfd and amdgpu into one module
- CEC over DP AUX support
- Picasso APU support + VCN dynamic powergating
- Raven2 APU support
- Vega20 enablement + kfd support
- ACP powergating improvements
- ABGR/XBGR display support
- VCN jpeg support
- xGMI support
- DC i2c/aux cleanup
- Ycbcr 4:2:0 support
- GPUVM improvements
- Powerplay and powerplay endian fixes
- Display underflow fixes
vmwgfx:
- Move vmwgfx specific TTM code to vmwgfx
- Split out vmwgfx buffer/resource validation code
- Atomic operation rework
bochs:
- use more helpers
- format/byteorder improvements
qxl:
- use more helpers
i915:
- GGTT coherency getparam
- Turn off resource streamer API
- More Icelake enablement + DMC firmware
- Full PPGTT for Ivybridge, Haswell and Valleyview
- DDB distribution based on resolution
- Limited range DP display support
nouveau:
- CEC over DP AUX support
- Initial HDMI 2.0 support
virtio-gpu:
- vmap support for PRIME objects
tegra:
- Initial Tegra194 support
- DMA/IOMMU integration fixes
msm:
- a6xx perf improvements + clock prefix
- GPU preemption optimisations
- a6xx devfreq support
- cursor support
rockchip:
- PX30 support
- rgb output interface support
mediatek:
- HDMI output support on mt2701 and mt7623
rcar-du:
- Interlaced modes on Gen3
- LVDS on R8A77980
- D3 and E3 SoC support
hisilicon:
- misc fixes
mxsfb:
- runtime pm support
sun4i:
- R40 TCON support
- Allwinner A64 support
- R40 HDMI support
omapdrm:
- Driver rework changing display pipeline ordering to use common code
- DMM memory barrier and irq fixes
- Errata workarounds
exynos:
- out-bridge support for LVDS bridge driver
- Samsung 16x16 tiled format support
- Plane alpha and pixel blend mode support
tilcdc:
- suspend/resume update
mali-dp:
- misc updates"
