For BXT, description of polarities of PORT_PLL_REF_SEL
has been reversed for newer Gen9LP steppings according to the
recent update in Bspec. This bit now should be set for
"Non-SSC" mode for all Gen9LP starting from B0 stepping.
v2: Only B0 and newer stepping should be affected by this
change.

Check functions are used by atomic to see if the new state will
be allowed. There's also a hw state checker which checks afterwards
that the committed state is correct. Rename it to hw state verifier
to reduce some confusion.

The modeset state verifier no longer has full access to the hardware,
instead it should only verify affected crtc's.
Looking for disabled stuff can be verified immediately after all crtc
disables have completed, while each enabled crtc can be verified right
after being enabled.

This will make it easier to keep the crtc checker when atomic
commit is reworked for asynchronous commits. This prevents checking
crtc's that were not part of the state. It's safe to verify disabled
encoders, connectors and dpll's that are not part of the state,
because during modeset connection_mutex is held.

git://anongit.freedesktop.org/drm-intel into drm-fixes
The qxl fix I've picked up quite some time ago, and unfortunately
neglected.
Then there's established timing fixes, of which particularly "drm/edid:
Fix parsing of EDID 1.4 Established Timings III descriptor" is quite
surprising. It looks like we've never got any of them right. I am not
sure what the full implications of this are. That combined with lack of
any details of real world bugs fixed made me decide against cc: stable.

When reading from the HWS page, we use barrier() to prevent the compiler
optimising away the read from the volatile (may be updated by the GPU)
memory address. This is more suited to READ_ONCE(); make it so.

Rather than call a function to compute the matching cachelines and

In order to simplify future patches, extract the
lazy_coherency optimisation our of the engine->get_seqno() vfunc into
its own callback.
v2: Rename the barrier to engine->irq_seqno_barrier to try and better
reflect that the barrier is only required after the user interrupt before
reading the seqno (to ensure that the seqno update lands in time as we
do not have strict seqno-irq ordering on all platforms).

v3: Comments for hangcheck paranoia. Mika wanted to keep the extra
barrier inside the hangcheck, just in case. I can argue that it doesn't
provide a barrier against anything, but the side-effects of applying the
barrier may prevent a false declaration of a hung GPU.

In order to ensure seqno/irq coherency, we currently read a ring register.
The mmio transaction following the interrupt delays the inspection of
the seqno long enough for the MI_STORE_DWORD_IMM to update the CPU
cache. However, it is only the memory timing that is important for the
purposes of the delay, we do not need nor desire the extra forcewake.

Currently for the case where there is enough space at the end of Ring
buffer for accommodating only the base request, the wrapround is done
immediately and as a result the base request gets added at the start
of Ring buffer. But there may not be enough free space at the beginning
to accommodate the base request, as before the wraparound, the wait was
effectively done for the reserved_size free space from the start of
Ring buffer. In such a case there is a potential of Ring buffer overflow,
the instructions at the head of Ring (ACTHD) can get overwritten.
Since the base request can fit in the remaining space, there is no need
to wraparound immediately. The wraparound will anyway happen later when
the reserved part starts getting used.

We are allocating backing using psbfb_alloc() and so
backing->stolen is always true. So we were freeing backing two times.
Moreover if we follow the execution path then we should be freeing
backing after we have released the helper. So remove the one which frees
backing before the helper is released.
While at it the error labels are also renamed to give a meaningful
name.

Seal the request and mark it as pending execution before we submit it to
hardware. We assume that the actual submission cannot fail (that
guarantee is provided by preallocating space in the request for the
submission). As we may inspect this state without holding any locks
during hangcheck we should apply a barrier to ensure that we do
not see a more recent value in the HWS than we are tracking.

After the GPU reset and we discard all of the incomplete requests, mark
the GPU as having advanced to the last_submitted_seqno (as having
completed the requests and ready for fresh work). The impact of this is
negligible, as all the requests will be considered completed by this
point, it just brings the HWS into line with expectations for external
viewers.

intel_update_max_cdclk() doesn't have a switch case for Broxton, so
dev_priv->max_cdclk_freq gets set to whatever clock frequency we're
currently running at (e.g., 144 MHz) rather than the true maximum. This
causes our max dotclock to also be set too low and in turn leads mode
verification to reject perfectly valid modes while loading EDID firmware
blobs.

Use plane size for relative data rate calculation. don't always use
pipe source width & height.
adjust height & width according to rotation.
use plane size for watermark calculations also.
v2: Address Matt's comments.
Use intel_plane_state->visible to avoid divide-by-zero error.
Where FB was present but not visible so causing total data rate to
be zero, hence divide-by-zero.

This patch sets the invert bit for hpd detection for each port
based on VBT configuration. Since each AOB can be designed to
depend on invert bit or not, it is expected if an AOB requires
invert bit, the user will set respective bit in VBT.
v2: Separated VBT parsing from the rest of the logic. (Jani)
v3: Moved setting invert bit logic to bxt_hpd_irq_setup()
and changed its logic to avoid looping twice. (Ville)
v4: Changed the logic to mask out the bits first and then
set them to remove need of temporary variable. (Ville)
v5: Moved defines to existing set of defines for the register
and added required breaks. (Ville)
