On CNL we may need to bump up the system agent voltage not only due
to CDCLK but also when driving DDI port with a sufficiently high clock.
To that end start tracking the minimum acceptable voltage for each crtc.
We do the tracking via crtcs because we don't have any kind of encoder
state. Also there's no downside to doing it this way, and it matches how
we track cdclk requirements on account of pixel rate.
v2: Allow disabled crtcs to use the min voltage
Add IS_CNL check to intel_ddi_compute_min_voltage() since
we're using CNL specific values there
s/intel_compute_min_voltage/cnl_compute_min_voltage/ since
the function makes hw specific assumptions about the voltage
values

As we faced in BXT, on CNL DDI_A_4_LANES is not
set as expected when system is boot with multiple
monitors connected. This result in wrong lane
setup impacting the max data rate available and
consequently blocking modeset on eDP, resulting
in a blank screen.
Most of CNL SKUs don't support DDI-E.
The only SKU that supports DDI-E is the same
that supports the full A/E split called DDI-F.
Also when DDI-F is used DDI-E cannot be used because
they share Interrupts. So DDI-E is almost useless.
Anyways let's consider this is possible and rely on
VBT for that.
This patch was initialy start by Clint, but required
many changes including full commit message. So
Credits entirely to Clint for finding this.

Along with simplification I removed the debug

are grouped.
v3: Split the conditions even more as suggested by Ville.

Originally we set the priority to max upon inserting the request into
the execlists queue (and removing it from the scheduler lists). We could
then use the prio==INT_MAX as a shortcut within execlists_schedule() to
detect the end of the dependency chain. Since commit 1f181225f8
("drm/i915/execlists: Keep request->priority for its lifetime") this is
no longer true as we use the request completion as an indicator the
schedule dependency chain is complete instead. (This allows us to then
reschedule requests even when its context is in flight.) However, this
makes the GEM_BUG_ON() inside execlists_schedule() racy as we may change
the rq->prio at the same time. As the assertion is useful, let's keep
the assertion and remove the micro-optimisation.

Back in commit a4b2b01523 ("drm/i915: Don't mark an execlists
context-switch when idle") we noticed the presence of late
context-switch interrupts. We were able to filter those out by looking
at whether the ELSP remained active, but in commit beecec9017
("drm/i915/execlists: Preemption!") that became problematic as we now
anticipate receiving a context-switch event for preemption while ELSP
may be empty. To restore the spurious interrupt suppression, add a
counter for the expected number of pending context-switches and skip if
we do not need to handle this interrupt to make forward progress.
v2: Don't forget to switch on for preempt.
v3: Reduce the counter to a on/off boolean tracker. Declare the HW as
active when we first submit, and idle after the final completion event
(with which we confirm the HW says it is idle), and track each source
of activity separately. With a finite number of sources, it should aide
us in debugging which gets stuck.

When we park the engine (upon idling), we kill the irq tasklet. However,
to be sure that it is not restarted by a spurious interrupt after doing so,
flush the interrupt handler before parking. As we only park the engines
when we believe the system is idle, there should not be any interrupts to
distrub us; so flushing the final in-flight interrupt should be sufficient.
(However, we are still dependent on the HW behaving in an orderly and
timely fashion, which we shall endeavour to improve upon later.)

In the idle worker we drop the prolonged GT wakeref used to cover such
essentials as interrupt delivery. (When a CS interrupt arrives, we also
assert that the GT is awake.) However, it turns out that 10ms is not
long enough to be assured that the last CS interrupt has been delivered,
so bump that to 200ms, and move the entirety of that wait to before we
take the struct_mutex to avoid blocking. As this is now a potentially
long wait, restore the earlier behaviour of bailing out early when a new
request arrives.

Replace instances of drm_framebuffer_reference/unreference() with
*_get/put() suffixes and drm_dev_unref with *_put() suffix

kernel use of *_get/put suffixes.

Otherwise we are blasting other bits in GEN8_L3SQCREG1 that might be important
(although we probably aren't at the moment because 0 seems to be the default

write")] there is no need to save space for them in the list of context
workarounds.
