When (size != 0 || ptrs->lvds_ entries != 3), the program tries to
free() the ptrs. However, the ptrs is not created by calling kzmalloc(),
but is obtained by pointer offset operation.
This may lead to memory leaks or undefined behavior.
Fix this by replacing the arguments of kfree() with ptrs_block.

bigjoiner_pipes() doesn't consider that:
- RKL only has three pipes
- some pipes may be fused off
This means that intel_atomic_check_bigjoiner() won't reject
all configurations that would need a non-existent pipe.
Instead we just keep on rolling witout actually having
reserved the slave pipe we need.
It's possible that we don't outright explode anywhere due to
this since eg. for_each_intel_crtc_in_pipe_mask() will only
walk the crtcs we've registered even though the passed in
pipe_mask asks for more of them. But clearly the thing won't
do what is expected of it when the required pipes are not
present.
Fix the problem by consulting the device info pipe_mask already
in bigjoiner_pipes().

Use the AUX_IO_A display power domain only for eDP on port A where PSR

while the output is enabled - ensured by AUX_IO_A domain not enabling

This change prepares for the next patch enabling DC states on all ports

When doing HDMI+non-HDMI cloning the other sink can't get
the infoframes/etc. so stuff like limited range output is
not a good idea.
Similarly when doing HDMI+HDMI cloning on g4x (only platform
where we allow it) only one of the ports can receive infoframes
and so again using any fancy stuff is a bad idea. We also don't
track the inforames/audio state per-port so we'd end up with
some kind of random mismash state when multipled encoders try
to compute the same stuff. And the hardware will in fact
automagically disable audio/infoframe transmission if you try
to enable it for multiple HDMI ports at the same time.
Thus disable all HDMI specific features when cloning.

Panel power off delay is the time the panel power needs to remain off
after being switched off, before it can be switched on again.
For the purpose of respecting panel power off delay at driver probe,
assuming the panel was last switched off at driver probe is overly
pessimistic. If the panel was never on, we'd end up waiting for no
reason.
We don't know what has happened before kernel boot, but we can make some
assumptions:
- The panel may have been switched off right before kernel boot by some
pre-os environment.
- After kernel boot, the panel may only be switched off by i915.
- At i915 driver probe, only a previously loaded and removed i915 may
have switched the panel power off.
With these assumptions, we can initialize the last power off time to
kernel boot time, if we also ensure i915 driver remove waits for the
panel power off delay after switching panel power off.
This shaves off the time it takes from kernel boot to i915 probe from
the first panel enable, if (and only if) the panel was not already
enabled at boot.
The encoder destroy hook is pretty much the last place where we can
wait, right after we've ensured the panel power has been switched off,
and before the whole encoder is destroyed.

Turns out many of the files that need i915_reg.h get it implicitly via
{display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h
-> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h,
makes sense to drop it, but that requires adding quite a few new
includes all over the place.
Prefer including i915_reg.h where needed instead of adding another
implicit include, because eventually we'll want to split up i915_reg.h
and only include the specific registers at each place.
Also some places actually needed i915_irq.h too.

Currently when opeating in split gamma mode we do the
"skip ever other sw LUT entry" trick in the low level
LUT programming/readout functions. That is very annoying
and a big hinderance to revamping the color management
uapi.
Let's get rid of that problem by making half sized copies
of the software LUTs and plugging those into the internal
{pre,post}_csc_lut attachment points (instead of the sticking
the uapi provide sw LUTs there directly).
With this the low level stuff will operate purely in terms
the hardware LUT sizes, and all uapi nonsense is contained
to the atomic check phase. The one thing we do lose is
intel_color_assert_luts() since we no longer have a way to
check that the uapi LUTs were correctly used when generating
the internal copies. But that seems like a price worth paying.

fb_ops and possibly perform a damage update. Handle all this in the
same functions and convert drivers. The functionality has been used
as part of the generic fbdev code for some time. The drivers don't
set struct drm_fb_helper.fb_dirty, so they will not be affected by
damage handling.
For I/O memory, fb helpers now provide drm_fb_helper_cfb_read() and
drm_fb_helper_cfb_write(). Several drivers require these. Until now

Rename struct drm_fb_helper.fbdev to info. The current name is
misleading as it overlaps with generic fbdev naming conventions.
Adapt to the usual naming in fbdev drivers by calling the field
'info'. No functional changes.

Prefer our own intel_crtc_needs_modeset() wrapper to
drm_atomic_crtc_needs_modeset() whenever we are dealing
with the intel_ types instead of drm_ types. Makes things
a bit neater in general.

ilk/snb vs. ivb+ hardware is mostly identical except for the addition
of the split gamma mode on ivb. Thus we can share the csc_enable
and gamma_enable calculation for both variants. Pull that stuff
into a few helpers.
Note that this also fills in the missing ctm/degamma stuff into
ilk_color_check() pretty much, so for good measure let's also
add a few extra checks relating to that, although we still don't
expose ctm/degamma to userspace. But now it'll be trivial to do
so if we wish.

Since the pipe CSC sits between the degamma and gamma LUTs there
is no way to make us it for RGB->YCbCr conversion when both LUTs
are also active. Simply reject such combos.

Apart from the split gamma mode ivb+ LUTs work just like ilk+ LUTs.
So let's handle the special case, and then just fall back to
ilk_gamma_mode() to avoid having to duplicate the same logic.

Since pre-icl vs. icl+ handle the limited range
output stuff a bit differently it's probably
less confusing if we just pass that information
explicitly into ilk_csc_convert_ctm().
