Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"I Was Almost Tempted To Capitalise Every Word, but then I decided I
couldn't read it myself!
I've also got one pull request for the sti driver outstanding. It
relied on a commit in Greg's tree and I didn't find out in time, that
commit is in your tree now so I might send that along once this is
merged.
I also had the accidental misfortune to have access to a Skylake on my
desk for a few days, and I've had to encourage Intel to try harder,
which seems to be happening now.
Here is the main drm-next pull request for 4.4.
Highlights:
New driver:
vc4 driver for the Rasberry Pi VPU.
(From Eric Anholt at Broadcom.)
Core:
Atomic fbdev support
Atomic helpers for runtime pm
dp/aux i2c STATUS_UPDATE handling
struct_mutex usage cleanups.
Generic of probing support.
Documentation:
Kerneldoc for VGA switcheroo code.
Rename to gpu instead of drm to reflect scope.
i915:
Skylake GuC firmware fixes
HPD A support
VBT backlight fallbacks
Fastboot by default for some systems
FBC work
BXT/SKL workarounds
Skylake deeper sleep state fixes
amdgpu:
Enable GPU scheduler by default
New atombios opcodes
GPUVM debugging options
Stoney support.
Fencing cleanups.
radeon:
More efficient CS checking
nouveau:
gk20a instance memory handling improvements.
Improved PGOB detection and GK107 support
Kepler GDDR5 PLL statbility improvement
G8x/GT2xx reclock improvements
new userspace API compatiblity fixes.
virtio-gpu:
Add 3D support - qemu 2.5 has it merged for it's gtk backend.
msm:
Initial msm88896 (snapdragon 8200)
exynos:
HDMI cleanups
Enable mixer driver byt default
Add DECON-TV support
vmwgfx:
Move to using memremap + fixes.
rcar-du:
Add support for R8A7793/4 DU
armada:
Remove support for non-component mode
Improved plane handling
Power savings while in DPMS off.
tda998x:
Remove unused slave encoder support
