drm/tegra: Changes for v3.16-rc1

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.

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.

drm: Remove DRM_ARRAY_SIZE() for ARRAY_SIZE()

I cannot see a need to provide a DRM_ version of ARRAY_SIZE(), only used
in a few places. I suspect its usage has been spread by copy & paste
rather than anything else.

Let's just remove it for plain ARRAY_SIZE().

drm/edid: Store all supported hdmi deep color modes in drm_display_info

HDMI deep color setup must know which modes are supported if
it needs to degrade gracefully, as only 12 bpc / dc_36 is
guaranteed, but 10 bpc / dc_30 is optional. The maximum bpc
is not sufficient for this.

drm/radeon: hdmi deep color modes must obey clock limit of sink.

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
to be set, try to degrade gracefully to lower supported deep color
bpc or to standard 8 bpc if needed.

drm/radeon: stop poisoning the GART TLB

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.

Revert "drm/radeon: use variable UVD clocks"

This caused reduced performance for some users with advanced post

the advanced post processing to fit within the lower power state
envelope.
