9034f9c4e2 drm/i915: Share {csc,gamma}_enable calculation for ilk/snb vs. ivb+ 
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.

4c0119dd0a drm/i915: Reject YCbCr output with degamma+gamma on pre-icl 
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.

6d5e733f3a drm/i915: Reuse ilk_gamma_mode() on ivb+ 
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.

8f079f0883 drm/i915: Split ivb_load_lut_ext_max() into two parts 
Split the EXT2_MAX register programming into its own function.
More in line with the whole "cobble together stuff from small
pieces" approach used in this code.

The EXT(2)_MAX registers are also not really part of the
multi-segment section of the LUT, so hoist the calls to a
higher level, just like we do in other gamma modes as well.

d755f89220 drm/i915/psr: Send update also on invalidate 
Currently we are observing mouse cursor stuttering when using
xrandr --scaling=1.2x1.2. X scaling/transformation seems to be
doing fronbuffer rendering. When moving mouse cursor X seems to
perform several invalidates and only one DirtyFB. I.e. it seems
to be assuming updates are sent to panel while drawing is done.

Earlier we were disabling PSR in frontbuffer invalidate call back
(when drawing in X started). PSR was re-enabled in frontbuffer
flush callback (dirtyfb ioctl). This was working fine with X
scaling/transformation. Now we are just enabling continuous full
frame (cff) in PSR invalidate callback. Enabling cff doesn't
trigger any updates. It just configures PSR to send full frame
when updates are sent. I.e. there are no updates on screen before
PSR flush callback is made. X seems to be doing several updates
in frontbuffer before doing dirtyfb ioctl.

Fix this by sending single update on every invalidate callback.

Note that the whole multi output support still looks very

8388eb067c drm/i915/sdvo: Extract intel_sdvo_has_audio() 
Pull the SDVO audio state computation into a helper.

This is almost identical to intel_hdmi_has_audio(),
except the sink capabilities are stored under intel_sdvo
rather than intel_hdmi. Might be nice to get rid of
this duplication eventually...

c3c5dc1d92 drm/i915/audio: Do the vblank waits 
The spec tells us to do a bunch of vblank waits in the audio
enable/disable sequences. Make it so.

The FIXMEs are nonsense since we do the audio disable very
early and enable very late, so vblank interrupts are in fact
enabled when we do this.

TODO not sure we actually want these since we don't even rely
on the hw ELD buffer, and these might be there just to give
the audio side a bit of time to respond to the unsol events.
OTOH they might be really needed for some other reason.

cbbda2ffbb drm/i915/audio: Split "ELD valid" vs. audio PD on hsw+ 
On the older platforms the audio presence detect bit is in
the port register, so it gets written outside audio codec hooks
and is this separate from the ELD valid toggling. Split the
operations into two steps on hsw+ to be more consistent with
both the other platforms and the spec. Also according to the
spec we might need some vblank waits between the two which
definitely needs them done separately.

7c8d74e813 drm/i915/audio: Use intel_de_rmw() for most audio registers 
The audio code does a lot of RMW accesses. Utilize
intel_de_rmw() to make that a bit less tedious.

There are still some hand rolled RMW left, but those have
a lot of code in between the read and write to calculate
the new value, so would need some refactoring first.

0234cda2ce drm/i915/audio: Make sure we write the whole ELD buffer 
Currently we only write as many dwords into the hardware
ELD buffers as drm_eld_size() tells us. That could mean the
remainder of the hardware buffer is left with whatever
stale garbage it had before, which doesn't seem entirely
great. Let's zero out the remainder of the buffer in case
the provided ELD doesn't fill it fully.

We can also sanity check out idea of the hardware ELD buffer's
size by making sure the address wrapped back to zero once
we wrote the entire buffer.

We currently read the ELD buffer size from hardware on g4x,

this and just do the hardware readout on all platforms,

TODO: should perhaps do the readout during driver init and
stash the results somewhere so that we could check that the
connector's ELD actually fits and not even try to enable audio
in that case...

9f4a51256f drm/i915/audio: Protect singleton register with a lock 
On the "ilk" platforms AUD_CNTL_ST2 is a singleton. Protect
it with the audio mutex in case we ever want to do parallel
RMW access to it.

Currently that should not happen since we only do audio
enable/disable from full modesets, and those are fully
serialized. But we probably want to think about toggling
audio on/off from fastsets too.

The hsw codepaths already have the same locking.
g4x should not need it since it can only do audio to a
single port at a time, which means it's actually broken
in more ways than this atm.
