Polling to make sure the current GPU frequency matches the last
requested frequency should not be necessay, and if there's some
throttling involved, the two might not match anyway.
Since we're still seeing this trigger occasionally, and it just
introduces a rather pointless 10 ms delay, it seems like better
to kill it off.

The RPS register writing routines use the current value of min/max to
set certain limits and interrupt gating. If we set those afterwards, we
risk setting up the hw incorrectly and losing power management events,
and worse, trigger some internal assertions.
Reorder the calling sequences to be correct, and remove the then
unrequired clamping from inside set_rps(). And for a bonus, fix the bug
of calling gen6_set_rps() from Valleyview.

When the hardware frame counter reads 0xffffff and we're already past
vblank start, we'd return 0x1000000 as the vblank counter value. Once
we'd cross into the next frame's active portion, the vblank counter
would wrap to 0. So we're reporting two different vblank counter values
for the same frame.
Fix the problem by masking the cooked value by 0xffffff to make sure
the counter wraps already after vblank start.

drm-intel-nightly integration branch I need to resolve all the
oustanding conflicts in drm/i915 with a backmerge to make the 60+
patches apply properly.
We'll propably have some fun because Linus will come up with a
slightly different merge solution.
Conflicts:
drivers/gpu/drm/i915/i915_dma.c
drivers/gpu/drm/i915/i915_drv.c
drivers/gpu/drm/i915/intel_crt.c
drivers/gpu/drm/i915/intel_ddi.c
drivers/gpu/drm/i915/intel_display.c
drivers/gpu/drm/i915/intel_dp.c
drivers/gpu/drm/i915/intel_drv.h
All rather simple adjacent lines changed or partial backports from
-next to -fixes, with the exception of the thaw code in i915_dma.c.
That one needed a bit of shuffling to restore the intent.
Oh and the massive header file reordering in intel_drv.h is a bit
trouble. But not much.

Even though we only check for unclaimed registers while we're writing

that. To avoid this error, just avoid touching power domains that are
not enabled.
Use kzalloc so we're sure all the disabled domains will be zeroed on
the error state file. We already print the information that is enough
to discover if the power well is enabled on the error state file, so
this should not be a problem.

We need to reset the DP scrambler on every vsync to get stable CRCs.
And since we can't use the normal pipe CRC on DP ports on g4x we
really need them to be able to test modesetting issues on (e)DP
outputs.
Note that the DC balance reset is for SDVO port CRCs so we don't
strictly need it. But better safe than sorry (and it's a nice template
in case we ever want to grab port CRCs for e.g. audio checking).

On gmch platforms the normal pipe source CRC registers don't work for
DP and TV encoders. And on newer platforms the single pipe CRC has
been replaced by a set of CRC at different stages in the platform.
Now most of our userspace tests don't care one bit about the exact
CRC, they simply want something that reflects any changes on the
screen. Hence add a new auto target for platform agnostic tests to
use.
v2: Pass back the adjusted source so that it can be shown in debugfs.
v3: I seem to be unable to get a stable CRC for DP ports. So let's
just disable them for now when using the auto mode. Note that
testcases need to be restructured so that they can dynamically skip
connectors. They also first need to set up the desired mode
configuration, since otherwise the auto mode won't do the right thing.
v4: Don't leak the modeset mutex on error paths.
v5: Spelling fix for the i9xx auto_source function.

Incorrect definition DPIO_TX3_SWING_CTL4.
From Ville's review: "Based on the specs, the typo meant that HDMI B
ended up using "incorrect" de-emphasis for the TMDS data lanes."

Now we only print messages when we actually enable VDD and when we
actually disable VDD.
The changes in the last commit triggered a big number of messages
while the driver was being initialized, and I thought we were toggling
things on/off too many times, but that was not really true: we were
just being too verbose.

If the eDP output is disabled, then we try to use /dev/i2c-X file to
do i2c transations, we get a WARN from intel_dp_check_edp() saying
we're trying to do AUX communication with the panel off. So this
commit reorganizes the code so we enable the VDD at
intel_dp_i2c_aux_ch() instead of just the callers inside i915.ko.
This fixes the i2c subtest from the pc8 test of intel-gpu-tools on
machines that have eDP panels.

Just a few small fixes for radeon (audio regression fix,
stability fix, and an endian bug noticed by coverity).
* 'drm-fixes-3.12' of git://people.freedesktop.org/~agd5f/linux:
drm/radeon/dpm: fix incompatible casting on big endian
drm/radeon: disable bapm on KB
drm/radeon: use sw CTS/N values for audio on DCE4+
Here are 3 tiny fixes that are needed for 3.12-final for some serial
drivers. One of them is a revert of a broken patch, and two others are
fixes for reported bugs. All of these have been in linux-next for a
while, I forgot I had not sent them to you yet, my fault.
