This caused reduced performance for some users with advanced post
processing enabled. We need a better method to pick the
UVD state based on the amount of post processing required or tune
the advanced post processing to fit within the lower power state
envelope.

When we set the valid bit on invalid GART entries they are
loaded into the TLB when an adjacent entry is loaded. This
poisons the TLB with invalid entries which are sometimes
not correctly removed on TLB flush.
For stable inclusion the patch probably needs to be modified a bit.

Make sure that a hdmi deep color mode can't exceed the max tmds
clock limit of a hdmi sink if such a limit is defined by edid.
If requested deep color bpc would exceed the limit given the mode

bpc or to standard 8 bpc if needed.

HDMI deep color setup must know which modes are supported if

drm/panel: Changes for v3.16-rc1
This set of commits contains a couple of fixes to existing panel drivers
and support for some new panels.
One commit touches the DRM core in that in modifies the MIPI DSI support
to hook up the shutdown function so that drivers can provide code that's
run on shutdown. This is used by a subsequent commit to make the simple
panel driver power off the backlight on shutdown.
* tag 'drm/panel/for-3.16-rc1' of git://anongit.freedesktop.org/tegra/linux:
drm/panel: simple - Add AUO B133XTN01 panel support
drm/panel: simple - Disable panel on shutdown
drm/panel: add support for EDT ET057090DHU panel
drm/panel: Add support for EDT ETM0700G0DH6 and ET070080DH6 panels
drm/panel: ld9040: add power control sequence
drm/panel: s6e8aa0: silence array overflow warning
drm/dsi: Support device shutdown
The majority of these changes are a slew of cleanups across the board.
A more noteworthy change is the addition of drm_dev_set_unique() and the
conversion of the Tegra DRM driver to use it. This allows us to get rid
of the host1x drm_bus implementation. Other USB and platform drivers can
be changed in a similar way. Unfortunately for most PCI devices there is
some userspace that relies on the old functionality and cannot be as
easily converted.
HDMI and hardware cursor support is added for Tegra124. The SOR output
gains support for exposing CRCs via debugfs, which can be used for
automated testing. Many values that were hardcoded in the SOR/eDP code
are now computed at runtime to increase compatibility with more devices.

The currently hardcoded link parameters don't work on all eDP panels, so
compute the parameters at runtime depending on the mode and panel type
to allow the driver to cope with a wider variety of panels.
Note that the number of bits per pixel of the panel is still hardcoded,
but this can be addressed in a separate patch.
This is largely based on a patch by Stéphane Marchesin but the algorithm
was largely rewritten to be more readable and concise.

Adding this to docbook requires a largish set of changes to the comments
in drm_{pci,usb,platform}.c since they are doxygen-style rather than
proper kernel-doc and therefore mess with the docbook generation.
While at it, mark usage of drm_put_dev() as discouraged in favour of
