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"
