On some Cannonlake SKUs we have a dedicated Aux for port F,
that is only the full split between port A and port E.
There is still no Aux E for Port E, as in previous platforms,
because port_E still means shared lanes with port A.
v2: Rebase.
v3: Add couple missed PORT_F cases on intel_dp.
v4: Rebase and fix commit message.
v5: Squash Imre's "drm/i915: Add missing AUX_F power well string"
v6: Rebase on top of display headers rework.
v7: s/IS_CANNONLAKE/IS_CNL_WITH_PORT_F (DK)
v8: Fix Aux bits for Port F (DK)
v9: Fix VBT definition of Port F (DK).
v10: Squash power well addition to this patch to avoid
warns as pointed by DK.
v11: Clean up squashed commit message. (David)
v12: Remove unnecessary handling for older platforms (DK)
Adding AUX_F to PG2 following other existent ones. (DK)

The only difference is that this SKUs has the full
Port A/E split named as Port F.
But since SKUs differences don't matter on the platform
definition group and ids, let's merge all off them together.
v2: Really include the PCI IDs to the picidlist[];
v3: Add the PCI Id for another SKU (Anusha).
v4: Update IDs, really include to pciidlists again.
v5: Unify all GT2 IDs.
v6: Unify in a way that we don't break early-quirks.c
v7: Remove GT reference since it doesn't matter here (Paulo)
Also move IS_CNL_WITH_PORT_F macro to this patch to
make it easier for review this part and also to get
used sooner.
v8: Rebased on top of commit 5db47e37b3 ("Revert "drm/i915:
mark all device info struct with __initconst"")

drm_encoder_slave is the old way to write bridge drivers, for i2c
bridges only. It's deprecated, and definitely should not be used in
new drivers. This has absolutely nothing to do with the new bridge
driver infrastructure implemented by drm_bridge.
What's even strange is that arcpgu doesn't even use any of this, it
really only wants a plain normal drm_encoder. Nuke all the surplus
real estate.
v2: Actually git add after compile testing ...
v3: Clarify commit message and stop including drm_encoder_slave.h.

While running the kms_plane clipping test I noticed a similar problem to
the one described in Display WA #1175. In this case, similarly for
planes other than the cursor, with 1 or 3 pixels visible from the left
edge of the screen to the end of the plane and an odd plane X offset
used for clipping causes the same kind of underflow and display
corruption as described for WA #1175. Fix this in a similar way as that
WA rejecting planes ending <4 pixels from the left screen edge.
v2:
- Rebase on v2 of patch 1/1.

As described in the WA on GLK and CNL planes on the right edge of the
screen that have less than 4 pixels visible from the beginning of the
plane to the edge of the screen can cause FIFO underflow and display
corruption.
On GLK/CNL I could trigger the problem only if the plane was at the same
time also aligned to the top edge of the screen (after clipping) and
there were exactly 2 pixels visible from the start of the plane to the
right edge of the screen (so couldn't trigger it with 1 or 3 pixels
visible). Nevertheless, to be sure, I also applied the WA for these cases.
I also couldn't see any problem with the cursor plane and later Art
confirmed that it's not affected, so the WA is applied only for the
other plane types.
v2:

During a non-blocking commit, it is possible to return before the
commit_tail work is queued (-ERESTARTSYS, for example).
Since a reference on the crtc commit object is obtained for the pending
vblank event when preparing the commit, the above situation will leave
us with an extra reference.
Therefore, if the commit_tail worker has not consumed the event at the
end of a commit, release it's reference.
Changes since v1:
- Also check for state->event->base.completion being set, to
handle the case where stall_checks() fails in setup_crtc_commit().
Changes since v2:
- Add a flag to drm_crtc_commit, to prevent dereferencing a freed event.
i915 may unreference the state in a worker.

Allow drivers to provide a device wide .mode_valid() hook in addition to
the already existing crtc/encoder/bridge/connector hooks. This can be
used to validate device/driver wide constraings without having to add
those to the other hooks. And since we call this hook also for user
modes later on in the modeset we don't have to worry about anything the
hook has already rejected.
I also have some further ideas for this hook. Eg. we could replace the
drm_mode_set_crtcinfo(HALVE_V) call in drm_mode_convert_umode()/etc.
with a driver specific variant via this hook. At least on i915 we would
like to pass CRTC_STEREO_DOUBLE to that function instead, and then
we could safely use the crtc_ timings in all our .mode_valid() hooks,
which would allow us to reuse those hooks for validating the
adjusted_mode during a modeset.

We use 32bit bitmasks to track planes/crtcs/encoders/connectors.
Naturally we can only do that if the index of those objects stays
below 32. Issue a warning whenever we exceed that limit, hopefully
prompting someone to fix the problem.
For connectors the issue is a bit more complicated as they can
be created/destroyed at runtime due to MST. So the problem is no
longer a purely theoretical programmer error. As the connector
indexes are allocated via ida, we can simply limit the maximum
value the ida is allowed to hand out. The error handling is already
in place.
