Pull drm updates from Dave Airlie:
 "Here's the main drm pull request for 4.7, it's been a busy one, and
  I've been a bit more distracted in real life this merge window.  Lots
  more ARM drivers, not sure if it'll ever end.  I think I've at least

commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241
Author: Jesse Barnes

    drm: Rework vblank-wait handling to allow interrupt reduction.

to stay backwards-compatible with old UMS code that didn't even tell
the kernel when it did a modeset, so that the kernel could
save/restore vblank counters. At worst this means vblanks will be
somewhat funky on a setup that very likely no one still runs.

So let's just nuke it.

Plan B would be to set it unconditionally in drm_vblank_init for kms
drivers, instead of in each driver separately. So if this patch breaks
anything please only restore the hunks in drmP.h and drm_irq.c, plus
add a check for DRIVER_MODESET in drm_vblank_init.

Stumbled over this in a discussion on irc with Chris.

drm: Drop plane argument from __drm_atomic_helper_plane_destroy_state

2016-05-17T06:56:55+00:00

It's unused, and really this helper should only look at the state
structure and nothing else.

v2: Fix commit message (Laurent).

v3: Rebase onto mtk driver merge.

drm: Remove unused drm_device from drm_gem_object_lookup()

2016-05-17T06:47:30+00:00

drm_gem_object_lookup() has never required the drm_device for its file
local translation of the user handle to the GEM object. Let's remove the
unused parameter and save some space.

Merge tag 'topic/drm-misc-2016-05-04' of git://anongit.freedesktop.org/drm-intel into drm-next

2016-05-04T23:56:30+00:00

Ofc I promise just a few leftovers for drm-misc and somehow it's the
biggest pull. But really mostly trivial stuff:
- MAINTAINERS updates from Emil
- rename async to nonblock in atomic_commit to avoid the confusion between
nonblocking ioctl and async flip (= not vblank synced), from Maarten.
Needs to be regened with newer drivers, but probably only after -rc1 to
catch them all.
- actually lockless gem_object_free, plus acked driver conversion patches.
All the trickier prep stuff already is in drm-next.
- Noralf's nice work for generic defio support in our fbdev emulation.
Keeps the udl hack, and qxl is tested by Gerd.

drm/vc4: Add missing render node support

2016-05-02T23:18:10+00:00

There shouldn't be any other driver support necessary, since none of
the driver-specific ioctls ever required auth, and none of them deal
with modesetting.

drm/vc4: Add support for gamma ramps.

2016-05-02T23:17:10+00:00

We could possibly save a bit of power by not requesting gamma
conversion when the ramp happens to be 1:1, but at least if all the
CRTCs are off the SRAM will be disabled.

This should fix brightness sliders in a lot of fullscreen games.

drm/vc4: Rename async to nonblock.

2016-05-02T14:38:19+00:00

The async name is deprecated and should be changed to nonblocking.

drm/vc4: Kick out the simplefb framebuffer before we set up KMS.

2016-04-20T00:31:56+00:00

If we don't, then simplefb stays loaded on /dev/fb0 even though
scanout isn't happening from simplefb's memory area any more, and you
end up with no console.
