Linus Torvalds a09e9a7a4b 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"

Daniel Vetter b5dc0d108c drm/imx: kill firstopen callback
This thing seems to do some kind of delayed setup. Really, real kms
drivers shouldn't do that at all. Either stuff needs to be dynamically
hotplugged or the driver setup sequence needs to be fixed.

This patch here just moves the setup at the very end of the driver
load callback, with the locking adjusted accordingly.

v2: Also move the corresponding put from ->lastclose to ->unload.

Daniel Vetter b0e898ac55 drm: remove FASYNC support
So I've stumbled over drm_fasync and wondered what it does. Digging
that up is quite a story.

First I've had to read up on what this does and ended up being rather
bewildered why peopled loved signals so much back in the days that
they've created SIGIO just for that ...

Then I wondered how this ever works, and what that strange "No-op."
comment right above it should mean. After all calling the core fasync
helper is pretty obviously not a noop. After reading through the
kernels FASYNC implementation I've noticed that signals are only sent
out to the processes attached with FASYNC by calling kill_fasync.

No merged drm driver has ever done that.

After more digging I've found out that the only driver that ever used
this is the so called GAMMA driver. I've frankly never heard of such a
gpu brand ever before. Now FASYNC seems to not have been the only bad
thing with that driver, since Dave Airlie removed it from the drm
driver with prejudice:

commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed
Author: Dave Airlie <airlied@linux.ie>
Date:   Sun Aug 29 12:04:35 2004 +0000

    Drop GAMMA DRM from a great height ...

Long story short, the drm fasync support seems to be doing absolutely
nothing. And the only user of it was never merged into the upstream
kernel. And we don't need any fops->fasync callback since the fcntl
implementation in the kernel already implements the noop case
correctly.

So stop this particular cargo-cult and rip it all out.

v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers
(somehow I've missed that one in staging). Also drop the reference in
the drm DocBook. ARM compile-fail reported by Rob Clark.

v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this
patch here.

v4: Actually git add ... tsk.

Daniel Vetter 43387b37fa drm/gem: create drm_gem_dumb_destroy
All the gem based kms drivers really want the same function to
destroy a dumb framebuffer backing storage object.

So give it to them and roll it out in all drivers.

This still leaves the option open for kms drivers which don't use GEM
for backing storage, but it does decently simplify matters for gem
drivers.

Markus Niebel 079461bf5d staging: drm/imx: set correct sync pins for display
partial fix of changes from
"staging: drm/imx: Add support for VGA via TVE on i.MX53"

Have to call imx_drm_crtc_panel_format_pins in imx_drm_crtc_panel_format
with the correct pins instead of (0, 0) This enables configuration of
correct waveforms for vsync / hsync for parallel display, LDB (i.MX53 and
i.MX6) as well as HDMI and MIPI (i.MX6)

Philipp Zabel 2ea42608ba staging: drm/imx: Add support for VGA via TVE on i.MX53
This adds display interface timings for the Television Encoder
connected to IPU DI1 on i.MX53 and adds some configuration
glue code to select which IPU signal generators / pins are to
be used for HSYNC/VSYNC signals.

The default configuration is pin2/pin3 for hsync/vsync. The
VGA connector on i.MX53-QSB uses pin7/pin8, and the analog
part of the DVI-I connector on MBa53 connects to pin4/pin6.

Sascha Hauer aecfbdb180 staging: drm/imx: add i.MX IPUv3 base driver
The IPU is the Image Processing Unit found on i.MX51/53/6 SoCs. It
features several units for image processing, this patch adds support
for the units needed for Framebuffer support, namely:

- Display Controller (dc)
- Display Interface (di)
- Display Multi Fifo Controller (dmfc)
- Display Processor (dp)
- Image DMA Controller (idmac)

This patch is based on the Freescale driver, but follows a different
approach. The Freescale code implements logical idmac channels and
the handling of the subunits is hidden in common idmac code pathes
in big switch/case statements. This patch instead just provides code
and resource management for the different subunits. The user, in this
case the framebuffer driver, decides how the different units play
together.

The IPU has other units missing in this patch:

- CMOS Sensor Interface (csi)
- Video Deinterlacer (vdi)
- Sensor Multi FIFO Controler (smfc)
- Image Converter (ic)
- Image Rotator (irt)
