Merge branch 'drm-core-next' of git://people.freedesktop.org/~airlied/linux
Pull main drm updates from Dave Airlie:
"This is the main merge window request for the drm.
It's big, but jam packed will lots of features and of course 0
regressions. (okay maybe there'll be one).
Highlights:
- new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
(qemu only). These drivers use the generic modesetting drivers.
- initial prime/dma-buf support for i915, nouveau, radeon, udl and
exynos
- switcheroo audio support: so GPUs with HDMI can turn off the sound
driver without crashing stuff.
- There are some patches drifting outside drivers/gpu into x86 and
EFI for better handling of multiple video adapters in Apple Macs,
they've got correct acks except one trivial fixup.
- Core:
edid parser has better DMT and reduced blanking support,
crtc properties,
plane properties,
- Drivers:
exynos: add 2D core accel support, prime support, hdmi features
intel: more Haswell support, initial Valleyview support, more
hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
cleanups and fixes
radeon: more HDMI audio support, improved GPU lockup recovery
support, remove nested mutexes, less memory copying on PCIE, fix
bus master enable race (kexec), improved fence handling
gma500: cleanups, 1080p support, acpi fixes
nouveau: better nva3 memory reclocking, kepler accel (needs
external firmware rip), async buffer moves on nv84+ hw.
I've some more dma-buf patches that rely on the dma-buf merge for vmap
stuff, and I've a few fixes building up, but I'd decided I'd better
get rid of the main pull sooner rather than later, so the audio guys
are also unblocked."
Fix up trivial conflict due to some duplicated changes in
drivers/gpu/drm/i915/intel_ringbuffer.c
