Maarten Lankhorst 81e257e964 drm/atomic: Make drm_atomic_legacy_backoff reset crtc->acquire_ctx
Atomic updates may acquire more state than initially locked through
drm_modeset_lock_crtc, running with heavy stress can cause a

Dave Airlie f939a5f432 Merge branch 'drm-fixes-4.7' of git://people.freedesktop.org/~agd5f/linux into drm-fixes
A bit bigger than I would normally like, but most of the large changes are
for polaris support and since polaris went upstream in 4.7, I'd like
to get the fixes in so it's in good shape when the hw becomes available.
The major changes only touch the polaris code so there is little chance
for regressions on other asics.  The rest are just the usual collection
of bug fixes.

Since HW trigger mode was suppoted we have faced with a issue
that Display panel didn't work correctly when trigger mode was changed
in booting time.
For this, we keep trigger mode with SW trigger mode in default mode
like we did before.

However, we will need to consider PSR(Panel Self Reflash) mode to resolve
this issue fundamentally later.

Lyude 1e3fa0acfe drm/i915/fbc: Disable on HSW by default for now
>From https://bugs.freedesktop.org/show_bug.cgi?id=96461 :

This was kind of a difficult bug to track down. If you're using a
Haswell system running GNOME and you have fbc completely enabled and
working, playing videos can result in video artifacts. Steps to
reproduce:

- Run GNOME
- Ensure FBC is enabled and active
- Download a movie, I used the ogg version of Big Buck Bunny for this
- Run `gst-launch-1.0 filesrc location='some_movie.ogg' ! decodebin !
  glimagesink` in a terminal
- Watch for about over a minute, you'll see small horizontal lines go
  down the screen.

For the time being, disable FBC for Haswell by default.

Stefan Richter reported kernel freezes (no video artifacts) when fbc
is on.  (E3-1245 v3 with HD P4600; openbox and some KDE and LXDE
applications, thread begins at https://lkml.org/lkml/2016/4/26/813).
We also got reports from Steven Honeyman on openbox+roxterm.

v2 (From Paulo):
  - Add extra information to the commit message
  - Add Fixes tag
  - Rebase

Commit 3424e3a4f8 ("drm: bridge: analogix/dp: split exynos dp driver to
bridge directory") split the Exynos DP core driver into a core driver and
a bridge driver for the Analogix chip since that is also used by Rockchip.

But the change introduced a regression causing a NULL pointer dereference
when trying to access an uninitialized connector in the driver .get_modes:

Fix this by instead of having a connector struct for both the Exynos and
Analogix drivers, just use the connector initialized in the bridge driver.

Lee Jones 0e289e534a ARM: dts: STi: stih407-family: Disable reserved-memory co-processor nodes
This patch fixes a non-booting issue in Mainline.

When booting with a compressed kernel, we need to be careful how we
populate memory close to DDR start.  AUTO_ZRELADDR is enabled by default
in multi-arch enabled configurations, which place some restrictions on
where the kernel is placed and where it will be uncompressed to on boot.

AUTO_ZRELADDR takes the decompressor code's start address and masks out
the bottom 28 bits to obtain an address to uncompress the kernel to
(thus a load address of 0x42000000 means that the kernel will be
uncompressed to 0x40000000 i.e. DDR START on this platform).

Even changing the load address to after the co-processor's shared memory
won't render a booting platform, since the AUTO_ZRELADDR algorithm still
ensures the kernel is uncompressed into memory shared with the first
co-processor (0x40000000).

Another option would be to move loading to 0x4A000000, since this will
mean the decompressor will decompress the kernel to 0x48000000. However,
this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of
memory would essentially be wasted for no good reason.

Until we can work with ST to find a suitable memory location to
relocate co-processor shared memory, let's disable the shared memory
nodes.  This will ensure a working platform in the mean time.

NB: The more observant of you will notice that we're leaving the DMU
shared memory node enabled; this is because a) it is the only one in
active use at the time of this writing and b) it is not affected by
the current default behaviour which is causing issues.

Linus Torvalds e80dac114c USB fixes for 4.7-rc4
Here are a bunch (65) of USB fixes for 4.7-rc4.  Sorry about the
 quantity, I've been slow in getting these out.  The majority are the
 "normal" gadget, musb, and xhci fixes, that we all are used to.  There
 are also a few other tiny fixes resolving a number of reported issues
 that showed up in 4.7-rc1.
 
 All of these have been in linux-next.

Here are a small number of debugfs, ISA, and one driver core fix for 4.7-rc4.
 
 All of these resolve reported issues.  The ISA ones have spent the least
 amount of time in linux-next, sorry about that, I didn't realize they
 were regressions that needed to get in now (thanks to Thorsten for the
 prodding!) but they do all pass the 0-day bot tests.  The others have
 been in linux-next for a while now.
 
 Full details about them are in the shortlog below.
