94477bff39 drm/ttm: Make ttm_bo_mem_compat available
There are cases where it is desired to see if a proposed placement
is compatible with a buffer object before calling ttm_bo_validate().

This is the first of a 3-patch series to fix a black screen
issue observed on Ubuntu 16.04 server.

04319d89fb drm/vmwgfx: Add an option to change assumed FB bpp
Offer an option for advanced users who want larger modes at 16bpp.

This becomes necessary after the fix: "Work around mode set
failure in 2D VMs."  Without this patch, there would be no way
for existing advanced users to get to a high res mode, and the
regression is they will likely get a black screen after a software
update on their current VM.

7c20d213dd drm/vmwgfx: Work around mode set failure in 2D VMs
In a low-memory 2D VM, fbdev can take up a large percentage of
available memory, making them unavailable for other DRM clients.

Since we do not take fbdev into account when filtering modes,
we end up claiming to support more modes than we actually do.

As a result, users get a black screen when setting a mode too
large for current available memory.  In a low-memory VM
configuration, users can get a black screen for a mode as low
as 1024x768.

The current mode filtering mechanism keys off of
SVGA_REG_SUGGESTED_GBOBJECT_MEM_SIZE_KB, i.e. the maximum amount
of surface memory we have.  Since this value is a performance
suggestion, not a hard limit, and since there should not be much
of a performance impact for a 2D VM, rather than filtering out
more modes, we will just allow ourselves to exceed the SVGA's
performance suggestion.

Also changed assumed bpp to 32 from 16 to make sure we can
actually support all the modes listed.

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.

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

0b1e1eb762 drm: atmel-hlcdc: Fix OF graph parsing
atmel_hlcdc_create_outputs() iterates over OF graph nodes and releases
the node (using of_node_put()) after each iteration, which is wrong
since for_each_endpoint_of_node() is already taking care of that.

Move the of_node_put() call in the error path.

   most of volume of change in this branch is due to this.
 
 * There are a couple of _rcuidle fixes from Paul that touch common code and

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.

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.

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.
