GTIER and DEIER doesn't have same interface on HSW so this "or" operation
makes the information provided useless.
v2: since we have gtier variable already let's split for everybody
and avoid the strange | op.
Also avoid overriding the value that was set for vlv. In this case I
believe that we should reorganize the whole function, but I'll respect
the comment that ask to not touch the order and let this organization
work to be done later.
v3: moving VLV check to the right place.

Users often can't do anything about this since their vendors stopped
providing BIOS updates. Also we seem to be able to hack around it
with increased latency values, and thus far the only reports have
been for screens with really high resolutions. So tune it down to a
level where only developers can see it.
Also drop some of the end-user fluff.

Power users spot this and then get adventurous and try to adjust
module driver options. Nothing good ever came out of that, so
hide it better.

Since I've reworked psr support to no longer require x-tiling we don't
check any state protected by the Giant GEM Lock. So drop that check.
Also boo for lockdep_assert_held for not yelling when lockdep is
disabled.

Just like during booting the BIOS can leave the VDD bit enabled after
system resume. So apply the same state sanitization there too. This
fixes a problem where after resume the port power domain refcount gets
unbalanced.
v2:
- unchanged
v3:
- call edp sanitizing from the encoder reset handler (Daniel)

Check in vlv_crtc_clock_get if DPLL is enabled before calling dpio read.
It will not be enabled for DSI and avoid dpio read WARN dumps.
Absence of ->get_config was causing other WARN dumps as well. Update
dpll_hw_state as well correctly
v2: Address review comments by Daniel
- Check if DPLL is enabled rather than checking pipe output type
- set adjusted_mode->flags to 0 in compute_config rather than using
pipe_config->quirks
- Add helper function in intel_dsi_pll.c and use that in intel_dsi.c
- updated dpll_hw_state correctly
- Updated commit message and title
v3: Address review comments by Imre
- Proper masking of P1, M1 fields while computing divisors
- assert in case of bpp mismatch
- guard for divide by 0 while computing pclk
- Use ARRAY_SIZE instead of direct calculation

This will be needed by an upcoming patch too that needs to sanitize the
VDD state during resume. The additional async disabling is only needed
for the resume path, here it doesn't make a difference since we enable
VDD right after the sanitize call.

Gcc warns that addr might be used uninitialized. It may not, but I see
why gcc gets confused.
Additionally, hiding code with side-effects inside WARN_ON() argument
seems uncool, so I moved it outside.

Pull DRM updates from Dave Airlie:
"Like all good pull reqs this ends with a revert, so it must mean we
tested it,
[ Ed. That's _one_ way of looking at it ]
This pull is missing nouveau, Ben has been stuck trying to track down
a very longstanding bug that revealed itself due to some other
changes. I've asked him to send you a direct pull request for nouveau
once he cleans things up. I'm away until Monday so don't want to
delay things, you can make a decision on that when he sends it, I have
my phone so I can ack things just not really merge much.
It has one trivial conflict with your tree in armada_drv.c, and also
the pull request contains some component changes that are already in
your tree, the base tree from Russell went via Greg's tree already,
but some stuff still shows up in here that doesn't when I merge my
tree into yours.
Otherwise all pretty standard graphics fare, one new driver and
changes all over the place.
New drivers:
- sti kms driver for STMicroelectronics chipsets stih416 and stih407.

- mmio base page flipping
- lots of vlv/chv fixes.
- universal cursor planes
radeon:
- Hawaii fixes
- display scalar support for non-fixed mode displays
- new firmware format support
- dpm on more asics by default
- GPUVM improvements

- crtc renumbering
- add component support
- DT interaction changes.
tegra:
- load as module fixes
- eDP bpp and sync polarity fixed
- DSI non-continuous clock mode support
- better support for importing buffers from nouveau
msm:
- mdp5/adq8084 v1.3 hw enablement

This reverts commit 48ba813701eb14b3008edefef4a0789b328e278c.
Thanks to Chris:
"drm_file->is_master is not synomous with having drm_file->master ==
drm_file->minor->master. This is because drm_file->master is the same
for all drm_files of the same generation and so when there is a master,
every drm_file believes itself to be the master. Confusion ensues and
things go pear shaped when one file is closed and there is no master
anymore."

drm/tegra: Changes for v3.17-rc1
Mostly some cleanup all over the place. Pitch alignment limitations of
the display controller are now honored and job submission is 64-bit
safe.
The SOR output (used for eDP) properly configures sync signal polarities
according to the display mode rather than hard-coding them to some value
and the number of bits per color is now taken from the panel rather than
hard-coded to properly support 24-bit vs. 18-bit panels.
The DSI controller now properly supports non-continuous clock mode.
GEM objects can now have their flags and tiling mode modified via IOCTLs
to allow buffers imported from Nouveau to be properly displayed. Newer
generations of the Tegra display controller can also detile block linear
buffers at scan-out time.
Finally the driver now properly exports MODULE_DEVICE_TABLEs to allow it
to be automatically loaded when built as a module.
* tag 'drm/tegra/for-3.17-rc1' of git://anongit.freedesktop.org/tegra/linux:
drm/tegra: add MODULE_DEVICE_TABLEs

When tegra-drm.ko is built as a module, these MODULE_DEVICE_TABLEs allow
the module to be auto-loaded since the module will match the devices
instantiated from device tree.
(Notes for stable: in 3.14+, just git rm any conflicting file, since they
are added in later kernels. For 3.13 and below, manual merging will be
needed)

Since the device will no longer be used, may as well keep it in reset to
potentially save some power and make sure it is in a clean state the
next time it's probed.

Tegra20 and Tegra30 both required the buffer line stride to be aligned
on 8 byte boundaries. Tegra114 and Tegra124 increased the alignment to
64 bytes. Introduce a parameter to specify the alignment requirements
for each display controller and round up the pitch of newly allocated
framebuffers appropriately.

Job submission currently relies on the fact that struct drm_tegra_reloc
and struct host1x_reloc are the same size and uses a simple call to the
copy_from_user() function to copy them to kernel space. This causes the
handle to be stored in the buffer object field, which then needs a cast
to a 32 bit integer to resolve it to a proper buffer object pointer and
store it back in the buffer object field.
On 64-bit architectures that will no longer work, since pointers are 64
bits wide whereas handles will remain 32 bits. This causes the sizes of
both structures to because different and copying will no longer work.
Fix this by adding a new function, host1x_reloc_get_user(), that copies
the structures field by field.
While at it, use substructures for the command and target buffers in
struct host1x_reloc for better readability. Also use unsized types to
make it more obvious that this isn't part of userspace ABI.

Currently the tiling parameters of buffer objects can only be set at
allocation time, and only a single tiled mode is supported. This new
DRM_TEGRA_GEM_SET_TILING IOCTL allows more modes to be set and also
allows the tiling mode to be changed after the allocation. This will
enable the Tegra DRM driver to import buffers from a GPU and directly
scan them out by configuring the display controller appropriately.
To complement this, the DRM_TEGRA_GEM_GET_TILING IOCTL can query the
current tiling mode of a buffer object. This is necessary when importing
buffers via handle (as is done in Mesa for example) so that userspace
can determine the proper parameters for the 2D or 3D engines.

drm/panel: Changes for v3.17-rc1
Panels can now be more finely controlled via .prepare() and .unprepare()
callbacks in addition to .enable() and .disable(). New kerneldoc details
what they are supposed to do and when they should be called.
The simple panel driver gained support for a couple of new panels and it
is now possible to specify additional delays during power up and power
down sequences if panels require it.
DSI devices can now advertise that they support non-continuous clock
mode which will allow DSI host controllers to disable the high speed
clock after transmissions to save power.

simple-panel is not a valid panel model, so there is no data (video
timings, etc.) associated with it. Therefore drivers can't do anything
useful with it, so it should not appear in the table of OF matches.
Device trees will always need to specify the exact model of the panel.
