70b01f07db drm/nouveau/mc: allow for local definition of reset bits
With the addition of PTOP-specified reset bits, it makes more sense to
move the definitions here rather than in individual subdev

c6007dc4e5 drm/nouveau/devinit/gf100: make devinit on resume safer
In case of successful suspend, devinit will have to be run and this is
the behavior currently hardcoded. However, as FD bug 94725 suggests,
there might be cases where runtime suspend leaves the GPU powered, and
in such cases devinit should not be run on resume.

On GF100+ we have a reliable way to know whether we need to run devinit.
Use it instead of blindly trusting the flag set by nvkm_devinit_fini().

The code around the NvForcePost also needs to be slightly reworked in
order to keep working.

4a5219edcd ARM: SoC driver updates for v4.7
Driver updates for ARM SoCs, these contain various things that touch
 the drivers/ directory but got merged through arm-soc for practical
 reasons. For the most part, this is now related to power management
 controllers, which have not yet been abstracted into a separate
 subsystem, and typically require some code in drivers/soc or arch/arm
 to control the power domains.
 
 Another large chunk here is a rework of the NVIDIA Tegra USB3.0
 support, which was surprisingly tricky and took a long time to
 get done.
 
 Finally, reset controller handling as always gets merged through here
 as well.

f7df9be067 ARM: DT updates for v4.7
These are all the updates to device tree files for 32-bit platforms,
 which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
 changesets, 450 files changed, 23340 insertions, 5216 deletions.
 
 The three platforms that are added with the "soc" branch are here as well,
 and we add some related machine files:
 
 - For Aspeed AST2400/AST2500, we get the evaluation platform and
   the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
 - For Oxnas 810SE, the Western Digital "My Book World Edition"
   is added as the only platform at the moment.
 - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
   are supported
 
 On the ARM Realview development platform, we now support all machines
 with device tree, previously only the board files were supported, which
 in turn will likely be removed soon.
 
 Qualcomm IPQ4019 is the second generation ARM based "Internet Processor",
 following the IPQ806x that is used in many high-end WiFi routers. This one
 integrates two ath10k wifi radios that were previously on separate chips.
 
 Other boards that got added for existing chips are:
 
 - On Ti OMAP family:
   - Amazon Kindle Fire, first generation, tablet and ebook reader
   - OnRISC Baltos iR 2110 and 3220 embedded industrial PCs
   - TI AM5728 IDK, TI AM3359 ICE-V2, and TI DRA722 Rev C EVM

tegra_dsi_connector_duplicate_state(), to duplicate the connector state
and destroys the state using the generic helper function,
drm_atomic_helper_connector_destroy_state(). Following commit
d2307dea14 ("drm/atomic: use connector references (v3)") there is
now an imbalance in the connector reference count because the Tegra
function to duplicate state does not take a reference when duplicating
the state information. However, the generic helper function to destroy
the state information assumes a reference has been taken and during
system suspend, when the connector state is destroyed, this leads to a
crash because we attempt to put the reference for an object that has
already been freed.

Fix this by calling __drm_atomic_helper_connector_duplicate_state() from
tegra_dsi_connector_duplicate_state() to ensure that we take a reference
on a connector if crtc is set. Note that this will also copy the
connector state a 2nd time, but this should be harmless.

By fixing tegra_dsi_connector_duplicate_state() to take a reference,
although a crash was no longer seen, it was then observed that after
each system suspend-resume cycle, the reference would be one greater
than before the suspend-resume cycle. Following commit d2307dea14
("drm/atomic: use connector references (v3)"), it was found that we
also need to put the reference when calling the function
tegra_dsi_connector_reset() before freeing the state. Fix this by
updating tegra_dsi_connector_reset() to call the function
__drm_atomic_helper_connector_destroy_state() in order to put the
reference for the connector.

255f0e7c41 drm/fb_helper: Fix references to dev->mode_config.num_connector
During boot, MST hotplugs are generally expected (even if no physical
hotplugging occurs) and result in DRM's connector topology changing.
This means that using num_connector from the current mode configuration
can lead to the number of connectors changing under us. This can lead to
some nasty scenarios in fbcon:

- We allocate an array to the size of dev->mode_config.num_connectors.
- MST hotplug occurs, dev->mode_config.num_connectors gets incremented.
- We try to loop through each element in the array using the new value
  of dev->mode_config.num_connectors, and end up going out of bounds
  since dev->mode_config.num_connectors is now larger then the array we
  allocated.

fb_helper->connector_count however, will always remain consistent while
we do a modeset in fb_helper.

Note: This is just polish for 4.7, Dave Airlie's drm_connector
refcounting fixed these bugs for real. But it's good enough duct-tape
for stable kernel backporting, since backporting the refcounting
changes is way too invasive.

14a3842a1d drm/i915/fbdev: Fix num_connector references in intel_fb_initial_config()
During boot time, MST devices usually send a ton of hotplug events
irregardless of whether or not any physical hotplugs actually occurred.
Hotplugs mean connectors being created/destroyed, and the number of DRM
connectors changing under us. This isn't a problem if we use
fb_helper->connector_count since we only set it once in the code,
however if we use num_connector from struct drm_mode_config we risk it's
value changing under us. On top of that, there's even a chance that
dev->mode_config.num_connector != fb_helper->connector_count. If the
number of connectors happens to increase under us, we'll end up using
the wrong array size for memcpy and start writing beyond the actual
length of the array, occasionally resulting in kernel panics.

Note: This is just polish for 4.7, Dave Airlie's drm_connector
refcounting fixed these bugs for real. But it's good enough duct-tape
for stable kernel backporting, since backporting the refcounting
changes is way too invasive.

d573de2d00 drm/amdgpu: create fence slab once when amdgpu module init.
This avoids problems with multiple GPUs.  For example,
if the first GPU failed before amdgpu_fence_init() was
called, amdgpu_fence_slab_ref is still 0 and it will
get decremented in amdgpu_fence_driver_fini().  This
will lead to a crash during init of the second GPU since
amdgpu_fence_slab_ref is not 0.

v2: add functions for init/exit instead of
    moving the variables into the driver.

9ab9cf058a drm/amd/powerplay: SCLK will have a big drop with low VDDC when PPlib was enabled.
SMC uses CurrSclkPllRange structure to keep track of what range of
PLL SCLK is sitting on.  Driver overwrites this value to 0 because
it's part of DPM table and driver doesn't program this.
This change will set this field to 0xFF every time there's a
init SMC table call.

Switch the order of the loops to walk the rates on the top
so we exhaust all DP 1.1 rate/lane combinations before trying
DP 1.2 rate/lane combos.

This avoids selecting rates that are supported by the monitor,

cda553725c drm/panel: simple: Set appropriate mode type
All modes exposed by simple panels should be tagged as driver defined
modes. Moreover, if a panel supports only one mode, this mode is
obviously the preferred one.

Doing this also fix a problem occurring when a 'video=' parameter is
passed on the kernel command line. In some cases the user provided mode
will be preferred over the simple panel ones, which might result in
unpredictable behavior.

There will some printed issues with above info, under certain

If ((BIT(0) | BIT(2)) & val) is never true, break will not happen and
delay_count will be max u32 value (?), and no DRM_INFO is printed.

Also if ((BIT(0) | BIT(2)) & val) is true at the last possible

b85881ddf2 drm/exynos/hdmi: Don't print error on deferral due to regulators
The regulators may not be available just because their driver's probe
function was just not executed and so the regulators not registered.

So, in this case the Exynos HDMI driver should not print logs since
a -EPROBE_DEFER is not really an error and that will just pollute
the kernel log and confuse users.

This patch prevents the following misleading messages to be printed:

2b66987533 drm/msm: Drop load/unload drm_driver ops
The load/unload drm_driver ops are deprecated. They should be removed as
they result in creation of devices visible to userspace even before
the drm_device is registered.

Drop these ops and use drm_dev_alloc/register and drm_dev_unregister/unref
to explicitly create and destroy the drm device in the msm platform
driver's bind and unbind ops. With this in use, the drm connectors are
only registered once the drm_device is registered.

It also fixes the issue of stray debugfs files after the msm module is
removed. With this, all the debugfs files are removed, and allows
successive module insertions/removals.

8208ed931e drm/msm: Centralize connector registration/unregistration
Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers
to the msm platform driver. This will simplify the task of ensuring that
the connectors are registered only after the drm_device itself is
registered.

The connectors' destroy ops are made to use kzalloc instead of
devm_kzalloc to ensure that that the connectors can be successfully
unregistered when the msm driver module is removed. The memory for the
connectors is unallocated when drm_mode_config_cleanup() is called
during either during an error or during driver remove.

The MDP4 driver tries to request and set voltages for regulators required
by the DSI PLLs.

Firstly, the MDP4 driver shouldn't manage the DSI regulators, this should
be handled in the DSI driver. Secondly, it shouldn't try to set a fixed
voltage for regulators. Voltage constraints should be specified on the
regulator via DT and managed by the regulator core.

f377d59729 drm/msm/dsi: Fix regulator API abuse
The voltage changing code in this driver is broken and should be
removed.  The driver sets a single, exact voltage on probe.  Unless
there is a very good reason for this (which should be documented in
comments) constraints like this need to be set via the machine
constraints, voltage setting in a driver is expected to be used in cases
where the voltage varies at runtime.

In addition client drivers should almost never be calling
regulator_can_set_voltage(), if the device needs to set a voltage it
needs to set the voltage and the regulator core will handle the case
where the regulator is fixed voltage.  If the driver simply skips
setting the voltage if it doesn't have permission then it should just
not bother in the first place.

Originally authored by Mark Brown <broonie@kernel.org>

Remove the min/max voltage data entries per SoC managed by the driver.
These aren't needed as we don't try to set voltages any more. Mention in
comments the voltages that each regulator expects.

a10e2bde5d drm/etnaviv: fix mmap operations for userptr and dma-buf objects
Add an indirect object operations call to allow distinct implementations
of the mmap operation based on the type of the object.

This ensures that the exporter is called to set up the mmap for imported
dma-bufs and disallows mapping of userptr objects through the DRM file,

2c80661d2e drm/fsl-dcu: use bus_flags for pixel clock polarity
The drivers current default configuration drives the pixel data
on rising edge of the pixel clock. However, most display sample
data on rising edge... This leads to color shift artefacts visible
especially at edges.

This patch changes the relevant defines to be useful and actually
set the bits, and changes pixel clock polarity to drive the pixel
data on falling edge by default. The patch also adds an explicit
pixel clock polarity flag to the display introduced with the driver
(NEC WQVGA "nec,nl4827hc19-05b") using the new bus_flags field to
retain the initial behavior.

1a738347df drm/radeon: fix DP link training issue with second 4K monitor
There is an issue observed when we hotplug a second DP
4K monitor to the system. Sometimes, the link training
fails for the second monitor after HPD interrupt
generation.

The issue happens when some queued or deferred transactions
are already present on the AUX channel when we initiate
a new transcation to (say) get DPCD or during link training.

We set AUX_IGNORE_HPD_DISCON bit in the AUX_CONTROL
register so that we can ignore any such deferred
transactions when a new AUX transaction is initiated.

f2d580b9a8 drm/core: Do not preserve framebuffer on rmfb, v4.
It turns out that preserving framebuffers after the rmfb call breaks
vmwgfx userspace. This was originally introduced because it was thought
nobody relied on the behavior, but unfortunately it seems there are
exceptions.

drm_framebuffer_remove may fail with -EINTR now, so a straight revert
is impossible. There is no way to remove the framebuffer from the lists
and active planes without introducing a race because of the different
locking requirements. Instead call drm_framebuffer_remove from a
workqueue, which is unaffected by signals.

Changes since v1:
- Add comment.
Changes since v2:
- Add fastpath for refcount = 1. (danvet)
Changes since v3:
- Rebased.
- Restore lastclose framebuffer removal too.

3d02b7fee9 drm/radeon: Allow setting shader registers using DMA/COPY packet3 on SI.
Mesa uses a COPY_DATA packet to copy the grid size for indirect dispatches
into COMPUTE_USER_DATA_*.

Setting those registers with a SET_SH_REG packet is allowed, not allowing
them with other packets seems like an oversight.

v2: Clarify commit message.
