ec1afbf4e1 drm/gk20a: add BAR instance
GK20A's BAR is functionally identical to NVC0's, but do not support
being ioremapped write-combined. Create a BAR instance for GK20A that
reflect that state.

e2a4e78cdc drm/nouveau/bar: add noncached ioremap property
Some BARs (like GK20A's) do not support being ioremapped write-combined.
Add a boolean property to the BAR structure and handle that case in the
Nouveau BO implementation.

8ba9ff1163 drm/nouveau: support for probing platform devices
Add a platform driver for Nouveau devices declared using the device tree
or platform data. This driver currently supports GK20A on Tegra
platforms and is only compiled for these platforms if Nouveau is
enabled.

Nouveau will probe the chip type itself using the BOOT0 register, so all
this driver really needs to do is to make sure the module is powered and
its clocks active before calling nouveau_drm_platform_probe().

Heavily based on work done by Thierry Reding.

61854bdb13 drm/gk104/pwr: implement PGOB disable method
As documented at:

ftp://download.nvidia.com/open-gpu-doc/gk104-disable-graphics-power-gating/1/gk104-disable-graphics-power-gating.txt

NVIDIA were not able document the steps necessary to detect whether this
is required or not at this time.  However, they did confirm that this
procedure is safe to perform unconditionally on GK104/6.  GK107 does not
have the power gating feature, and it was recommended that we do not
perform these steps there as the effects were not verified.

The disable path is from observing the binary driver, and not
documented in the link above.

This reverts commit b6d547791f.

The panel self refresh clearly isn't stable yet, and causes my laptop
(Haswell ULT in a Sony Vaio Pro) to have the screen lock up.  Maybe it
doesn't ever get out of self-refresh, or maybe there are gremlins in the
machine that get unhappy.  Regardless, it's broken, and it gets
reverted.

fdd508a641 drm/i915: Call .update_primary_plane in intel_{enable, disable}_primary_hw_plane()
Make the intel_{enable,disable}_primary_hw_plane() simply call
.update_primary_plane(), thus eliminating the rmw from these functions
which should help the poor old 830M.

Now we can also remove the .update_primary_plane() from the
.crtc_enable() hooks because we end up calling it via
intel_crtc_enable_planes()->intel_enable_primary_hw_plane().

This also has the nice benefit of making primary planes a bit closer to
the way we handle sprite planes during modesets.

v2: Just write 0 to DSPCNTR and DSPSURF/DSPADDR if the plane is (to be)
    disabled. Quicker, and more importantly avoids an oops when fb==NULL
    due to BIOS fb takeover failure.
    Pimp the commit message a bit (Matt)

Move the entire DSPCNTR register setup into the .update_primary_plane()
functions. That's where it belongs anyway and it'll also help 830M which
has the extra problem that plane registers reads will return the value
latched at the last vblank, not the value that was last written.

Also move DSPPOS and DSPSIZE setup there.

44c916d58b ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.

cb597bb3a2 drm: trylock modest locking for fbdev panics
In the fbdev code we want to do trylocks only to avoid deadlocks and
other ugly issues. Thus far we've only grabbed the overall modeset
lock, but that already failed to exclude a pile of potential
concurrent operations. With proper atomic support this will be worse.

So add a trylock mode to the modeset locking code which attempts all
locks only with trylocks, if possible. We need to track this in the
locking functions themselves and can't restrict this to drivers since
driver-private w/w mutexes must be treated the same way.

There's still the issue that other driver private locks aren't handled
here at all, but well can't have everything. With this we will at
least not regress, even once atomic allows lots of concurrent kms
activity.

Aside: We should move the acquire context to stack-based allocation in
the callers to get rid of that awful WARN_ON(kmalloc_failed) control
flow which just blows up when memory is short. But that's material for
separate patches.

v2:
- Fix logic inversion fumble in the fb helper.
- Add proper kerneldoc.

3d30a59bfc drm: Move ->old_fb from crtc to plane
Atomic implemenations for legacy ioctls must be able to drop locks.
Which doesn't cause havoc since we only do that while constructing
the new state, so no driver or hardware state change has happened.

The only troubling bit is the fb refcounting the core does - if
someone else has snuck in then it might potentially unref an
outdated framebuffer. To fix that move the old_fb temporary storage
into struct drm_plane for all ioctls, so that the atomic helpers can
update it.

v2: Fix up the error case handling as suggested by Matt Roper and just
grab locks uncoditionally - there's no point in optimizing the locking

d059f652e7 drm: Handle legacy per-crtc locking with full acquire ctx
So drivers using the atomic interfaces expect that they can acquire
additional locks internal to the driver as-needed. Examples would be
locks to protect shared state like shared display PLLs.

Unfortunately the legacy ioctls assume that all locking is fully done
by the drm core. Now for those paths which grab all locks we already
have to keep around an acquire context in dev->mode_config. Helper
functions that implement legacy interfaces in terms of atomic support
can therefore grab this acquire contexts and reuse it.

The only interfaces left are the cursor and pageflip ioctls. So add
functions to grab the crtc lock these need using an acquire context
and preserve it for atomic drivers to reuse.

v2:
- Fixup comments&kerneldoc.
- Drop the WARNING from modeset_lock_all_crtcs since that can be used
  in legacy paths with crtc locking.

v3: Fix a type on the kerneldoc Dave spotted.

10f637bf29 drm: Add drm_plane/connector_index
In the atomic state we'll have an array of states for crtcs, planes
and connectors and need to be able to at them by their index. We
already have a drm_crtc_index function so add the missing ones for
planes and connectors.

If it later on turns out that the list walking is too expensive we can
add the index to the relevant modeset objects.

Rob Clark doesn't like the loops too much, but we can always add an
obj->idx parameter later on. And for now reiterating is actually safer
since nowadays we have hotpluggable connectors (thanks to DP MST).

e2fcdaa9c9 drm/i915: Free pending page flip events at .preclose()
If there are pending page flips when the fd gets closed those page
flips may have events associated to them. When the page flip eventually
completes it will queue the event to file_priv->event_list, but that
may be too late and file_priv->event_list has already been cleaned up.
Thus we leak a bit of kernel memory in the form of the event structure.

To avoid such problems clear out such pending events from
intel_crtc->unpin_work at ->preclose(). Any event that already made it
to file_priv->event_list will get cleaned up by the drm_release_events()
a bit later.

We can ignore the file_priv->event_space accounting since file_priv is
going away. This is already how drm core deals with pending vblank
events, which are maintained by the drm core.

What saves us from a total disaster (ie. dereferencing and alrady
freed file_priv) is the fact that the fb descruction triggers a modeset
and there we wait for pending flips.

It looks like frobbing the cmnreset line on pne PHY disturbs the other
PHY on chv. The result is a black screen. On HDMI it's just a flash of
black, but DP usually falls over and can't get back up.

As a workaround set up the power domains so that both common lane
wells power up and down together. I also tried leaving the cmnreset
deasserted even the if the power well goes down but that didn't seem
acceptable to the PHY.

Not sure what happened on chv because a new register called FW9 is now
