3c30c7f7b0 drm/i915: Add I2C and DP-AUX char devices to debug kconfig 
These char devices exposing the driver's I2C and DP-AUX adapters for
user space tools are useful to debug display output related issues.
Enable them with the rest of additional driver debug options.

7a9e10253e drm/i915: Move priority bumping for flips earlier 
David found another issue with priority bumping from mmioflips, where we
are accessing the requests concurrently to them being retired and freed.
Whilst we are skipping the dependency if has been submitted, that is not
sufficient to stop the dependency from disappearing if another thread
retires that request. To prevent we can either employ the struct_mutex (or a
request mutex in the future) to serialise retiring before it is freed.
Alternatively, we need to keep the dependencies alive using RCU whilst
they are being accessed via the DFS.

3acd240175 drm/i915/debugfs: Increment return value of gt.next_seqno 
The i915_next_seqno read value is to be the next seqno used by the
kernel. However, in the conversion to atomics ops for gt.next_seqno, in
commit 28176ef4cf ("drm/i915: Reserve space in the global seqno during
request allocation"), this was changed from a post-increment to a
pre-increment. This increment was missed from the value reported by
debugfs, so in effect it was reporting the current seqno (last
assigned), not the next seqno.

1f3dc3e334 drm/i915: Initialize dev_priv->atomic_cdclk_freq at init time 
Looks like we're only initializing dev_priv->atomic_cdclk_freq
at resume and commit times, not at init time. Let's do that as
well.

We're now hitting the 'WARN_ON(intel_state->cdclk == 0)' in
hsw_compute_linetime_wm() on account of populating
intel_state->cdclk from dev_priv->atomic_cdclk_freq.
Previously we were mispopulating intel_state->cdclk with
dev_priv->cdclk_freq which always had a proper value at init
time and hence the WARN_ON() didn't trigger.

14676ec6b1 drm/i915: Fix cdclk vs. dev_cdclk mess when not recomputing things 
When we end up not recomputing the cdclk, we need to populate
intel_state->cdclk with the "atomic_cdclk_freq" instead of the
current cdclk_freq. When no pipes are active, the actual cdclk_freq
may be lower than what the configuration of the planes and
pipes would require from the point of view of the software state.

This fixes bogus WARNS from skl_max_scale() which is trying to check
the plane software state against the cdclk frequency. So any time
it got called during DPMS off for instance, we might have tripped
the warn if the current mode would have required a higher than
minimum cdclk.

ce1135c7de drm/i915: Complete requests in nop_submit_request 
Since the submit/execute split in commit d55ac5bf97 ("drm/i915: Defer
transfer onto execution timeline to actual hw submission") the
global seqno advance was deferred until the submit_request callback.
After wedging the GPU, we were installing a nop_submit_request handler
(to avoid waking up the dead hw) but I had missed converting this over
to the new scheme. Under the new scheme, we have to explicitly call
i915_gem_submit_request() from the submit_request handler to mark the
request as on the hardware. If we don't the request is always pending,
and any waiter will continue to wait indefinitely and hangcheck will not
be able to resolve the lockup.

On i.MX6SX the physical memory is placed above the 2GB mark, so the GPU
linear window has to be moved for the GPU to work at all. This doesn't
mix with the FAST_CLEAR feature, as the TS unit doesn't take the linear
window offset into account and will corrupt memory when used with a
non-zero offset.

Move the linear window if it's necessary for the GPU to work, but avoid
announcing FAST_CLEAR support to userspace in this case.

557800532e drm/etnaviv: Allow DRAW_INSTANCED commands 
Vivante GPUs with HALTI0 feature support a DRAW_INSTANCED command in the
command stream to draw a number of instances of the same geometry.

The information that has been figured out about the command can be found
here: https://github.com/etnaviv/etna_viv/blob/master/rnndb/cmdstream.xml#L270

This command is not allowed currently by the DRM driver because it
was not known before. This patch enables parsing it in command
streams and allows using it by userspace drivers.

dabdcdc982 drm/vmwgfx: Switch to mode_cmd2 
Surprisingly few changes needed to make it happen. Compile-tested
only. The idea is that this replaces the 2 patches from Ville's big
fb->format patch series as a prep patch. Only impact to later patches
should be the one instace added in this patch where we look at
fb->pixel_format (instead of fb->bpp and fb->depth), so minor
adjustements in the cocci-generated patches needed.

v2: Restore pitch computation in vmw_fb_kms_framebuffer (Sinclair).

31613268c0 drm/i915/audio: extend get_saved_enc() to support more scenarios 
In initialization, audio driver will call functions get_eld() and etc.
But at that time, audio driver may not know whether it is DP MST or not.
In the original function get_saved_enc(), if it is DP MST, it requires to
set the pipe to the correct value, otherwise, pipe to be -1.

Although audio driver can get the knowledge whether it is in DP MST mode
or not by reading the codec register. It will drop performance each time
before it calls the get_eld and other similar functions. As gfx driver can
easily know whether it is in DP MST mode or not. Let's extend the
get_saved_enc() function to handle the situation that audio driver
still sends the device id info even it is in DP SST mode and return
the correct intel_encoder instead of panic.
