4910403836 drm/radeon: fix speaker allocation setup
If the sad_count is 0, set the hw to stereo and change
the error message to a warn.  A lot of monitors don't
set the speaker allocation block.

377bd8a98d drm/radeon: use a fetch function to get the edid
We keep a cached version of the edid in radeon_connector which
we use for determining connectedness and when to enable certain
features like hdmi audio, etc.  When the user uses the firmware
interface to override the driver with some other edid the driver's
copy is never updated.  The fetch function will check if there
is a user supplied edid and update the driver's copy if there
is.

28ed756f1f Revert "drm/radeon/audio: don't set speaker allocation on DCE4+"
This reverts commit 555b1b651a.

Let's try this again for 3.13.  It's required for proper
interaction with alsa.  Was disabled previously in 3.12
to be on the safe side since it caused problems on older
asics.

0f57bca922 drm/radeon/audio: fix missing multichannel PCM SAD in some cases
The current code writing SADs to the audio registers seems to assume
that there is at most a single SAD per audio format.

However, that is not the case. Especially for PCM it is somewhat common
for sinks to have two SADs, one for 8-channel and one for 2-channel
audio, which may have different supported sample rates (i.e. the sink
supports stereo audio at higher sample rates than multichannel audio).

Because of this, only the 2-channel SAD may be used if it appears before
the 8-channel SAD. Unless other SADs require otherwise, this may cause
the ALSA HDA driver to allow stereo playback only.

Fix the code to pick the PCM SAD with the highest number of channels,
while merging the rate masks of PCM SADs with lower amount of channels
into the additional stereo rate mask byte.

Technically there are even more cases to handle (multiple non-PCM SADs
of the same type, more than two PCM SADs with varying channel counts,
etc), but those have not actually been encountered in the field and
handling them would be non-trivial.

Example affected EDID from Onkyo TX-SR674 specifying 192kHz stereo
support and 96kHz 8-channel support (and other 8-channel compressed
formats):

91915260ea Merge tag 'drm-intel-fixes-2013-11-07' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
Bit a bit -fixes pull request in the merge window than usual dua to two
feauture-y things:
- Display CRCs are now enabled on all platforms, including the odd DP case
  on gm45/vlv. Since this is a testing-only feature it should ever hurt,
  but I figured it'll help with regression-testing -fixes. So I left it
  in and didn't postpone it to 3.14.
- Display power well refactoring from Imre. Would have caused major pain
  conflict with the bdw stage 1 patches if I'd postpone this to -next.
  It's only an relatively small interface rework, so shouldn't cause pain.
  It's also been in my tree since almost 3 weeks already.

That accounts for about two thirds of the pull, otherwise just bugfixes:
- vlv backlight fix from Jesse/Jani
- vlv vblank timestamp fix from Jesse
- improved edp detection through vbt from Ville (fixes a vlv issue)
- eDP vdd fix from Paulo
- fixes for dvo lvds on i830M
- a few smaller things all over

Note: This contains a backmerge of v3.12. Since the -internal branch
always applied on top of -nightly I need that unified base to merge bdw
patches. So you'll get a conflict with radeon connector props when pulling
this (and nouveau/master will also conflict a bit when Ben doesn't
rebase). The backmerge itself only had conflicts in drm/i915.

There's also a tiny conflict between Jani's backlight fix and your sysfs
lifetime fix in drm-next.
