It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_connector_set_property.
The only special case is nouveau which used one function for both
pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2
vtables. But amounts to exactly the same.
What is rather strange here is how few drivers set this up, I suspect
the earlier patch to handle properties in the core did end up fixing a
pile of possible issues.

The driver stores lut values from the fbdev interface, and is able
to give them back, but does not appear to do anything with these
lut values. The generic fb helpers have replaced this function,
and may even have made the driver work for the C8 mode from the
fbdev interface. But that is untested.
Since the fb helpers .gamma_set and .gamma_get are obsolete,
remove the dead code.

this to allow querying modifiers per plane. Based on this, the client to

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
the entire panic handling code in our fbdev emulation. We might
restore kms panic output, but not through the bazillion of legacy
code layers called fbdev/fbcon, there's just no way to make that
work safely.
- With the module check change FBINFO_DEFAULT is always 0, so can be
removed too.
That removes another change to cargo-cult stuff in kms drivers, yay!

HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
- VIC for 4K modes for HDMI 1.4 sinks
- S3D information for S3D modes
As CEA-861-F has already defined VICs for 4K videomodes, this
patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
until the mode is 3D.

Commit 24f8e00a8a ("drm/i915: Prefer to report ENOMEM rather than
incur the oom for gfx allocations") has tried to remove disruptive OOM
killer because the userspace should be able to cope with allocation
failures.
At the time only __GFP_NORETRY could achieve that and it turned out that
this would fail the allocations just too easily. So "drm/i915: Remove
__GFP_NORETRY from our buffer allocator" removed it and hoped for a
better solution. __GFP_RETRY_MAYFAIL is that solution. It will keep
retrying the allocation until there is no more progress and we would go
OOM. Instead we fail the allocation and let the caller to deal with it.

Paulo had noticed that inside cnl_ddi_vswing_program
the case was handling voltage but with no indication
of type where a missing type could also take us to that
path. So my first attempt was to add a message to
let clear who trigger that path.
However DK had a better idea that is to handle the
missed type sooner before it might take to that path.
So this v2 here uses his approach.
v2: Handle missed type sooner.

For the vGPU workloads, now GVT-g use per vGPU scheduler, the per-ring
work_thread only pick workload belongs to the current vGPU. And with time
slice based scheduler, it waits all the engines become idle before do vGPU
switch. So we can run free dispatch in per-ring work_thread, different ring
running in different 'vGPU' won't happen.
For the workloads between vGPU and Host, this scheduler_mutex can't block
host to dispatch workload into other ring engines.
Here remove this mutex since it impacts the performance when applications
use more than 1 ring engines in 1 vgpu.
ring0 running in vGPU1, ring1 running in Host. Will happen.
ring0 running in vGPU1, ring1 running in vGPU2. Won't happen.

Commit fabef82562 ("drm/i915: Drop struct_mutex around frontbuffer
flushes") adds a dependency to ifbdev->vma when flushing the framebufer,
but the checks are only against the existence of the ifbdev->fb and not
against ifbdev->vma. This leaves a window of opportunity where we may
try to operate on the fbdev prior to it being probed (thanks to
asynchronous booting).

So far in an attempt to make sure all power wells get disabled during
display uninitialization the driver removed any secondary request bits
(BIOS, KVMR, DEBUG) that were set for a given power well. The known
source for these requests was DMC's request on power well 1 and the misc
IO power well. Since DMC is inactive (DC states are disabled) at the
point we disable these power wells, there shouldn't be any reason to
leave them on. However there are two problems with the above
assumption: Bspec requires that the misc IO power well stays enabled
(without providing a reason) and there can be KVMR requests that we
can't remove anyway (the KVMR request register is R/O). Atm, a KVMR
request can trigger a timeout WARN when trying to disable power wells.
To make the code aligned to Bspec and to get rid of the KVMR WARN, don't
try to remove the secondary requests, only detect them and stop polling
for the power well disabled state when any one is set.
Also add a comment about the timeout values required by Bspec when
enabling power wells and the fact that waiting for them to get disabled
is not required by Bspec.

What we want to assert based on the conditions required by Bspec is that
power well 2 is disabled, so no need to check for other power wells.
In addition we can only check if the driver's request is removed, the
actual state depends on whether the other request bits are set or not
(BIOS, KVMR, DEBUG). So check only the driver's request bit.
