Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm tree changes from Dave Airlie:
"This is the main drm pull request, I have some overlap with sound and
arm-soc, the sound patch is acked and may conflict based on -next
reports but should be a trivial fixup, which I'll leave to you!
Highlights:
- new drivers:
MSM driver from Rob Clark
- non-drm:
switcheroo and hdmi audio driver support for secondary GPU
poweroff, so drivers can use runtime PM to poweroff the GPUs. This
can save 5 or 6W on some optimus laptops.
- drm core:
combined GEM and TTM VMA manager
per-filp mmap permission tracking
initial rendernode support (via a runtime enable for now, until we get api stable),
remove old proc support,
lots of cleanups of legacy code
hdmi vendor infoframes and 4k modes
lots of gem/prime locking and races fixes
async pageflip scaffolding
drm bridge objects
- i915:
Haswell PC8+ support and eLLC support, HDMI 4K support, initial
per-process VMA pieces, watermark reworks, convert to generic hdmi
infoframes, encoder reworking, fastboot support,
- radeon:
CIK PM support, remove 3d blit code in favour of DMA engines,
Berlin GPU support, HDMI audio fixes
- nouveau:
secondary GPU power down support for optimus laptops, lots of
fixes, use MSI, VP3 engine support
- exynos:
runtime pm support for g2d, DT support, remove non-DT,
- tda998x i2c driver:
lots of fixes for sync issues
- gma500:
lots of cleanups
- rcar:
add LVDS support, fbdev emulation,
- tegra:
just minor fixes"
