Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"This is the main pull request for the drm for 4.3. Nouveau is
probably the biggest amount of changes in here, since it missed 4.2.
Highlights below, along with the usual bunch of fixes.
All stuff outside drm should have applicable acks.
Highlights:
- new drivers:
freescale dcu kms driver
- core:
more atomic fixes
disable some dri1 interfaces on kms drivers
drop fb panic handling, this was just getting more broken, as more locking was required.
new core fbdev Kconfig support - instead of each driver enable/disabling it
struct_mutex cleanups
- panel:
more new panels
cleanup Kconfig
- i915:
Skylake support enabled by default
legacy modesetting using atomic infrastructure
Skylake fixes
GEN9 workarounds
- amdgpu:
Fiji support
CGS support for amdgpu
Initial GPU scheduler - off by default
Lots of bug fixes and optimisations.
- radeon:
DP fixes
misc fixes
- amdkfd:
Add Carrizo support for amdkfd using amdgpu.
- nouveau:
long pending cleanup to complete driver,
fully bisectable which makes it larger,
perfmon work
more reclocking improvements
maxwell displayport fixes
- vmwgfx:
new DX device support, supports OpenGL 3.3
screen targets support
- mgag200:
G200eW support
G200e new revision support
- msm:
dragonboard 410c support, msm8x94 support, msm8x74v1 support
yuv format support
dma plane support
mdp5 rotation
initial hdcp
- sti:
atomic support
- exynos:
lots of cleanups
atomic modesetting/pageflipping support
render node support
- tegra:
tegra210 support (dc, dsi, dp/hdmi)
dpms with atomic modesetting support
- atmel:
support for 3 more atmel SoCs
new input formats, PRIME support.
- dwhdmi:
preparing to add audio support
- rockchip:
yuv plane support"
