The naming of tda998x_encoder_set_config() is a left-over from when
TDA998x was a slave encoder. Since this is part of the initialisation,
drop the _encoder from the name, and move it near tda998x_bind().

Check for audio support by the attached sink by consulting the EDID
prior to enabling audio over the TMDS link. We must consult the EDID
after calling drm_helper_probe_single_connector_modes(), as this can
use an override EDID, or load a replacement EDID.

The CEA 861B specification indicates the situations when we are able to
send each infoframe based on the version of the EDID's CEA extension.
Update the tda998x driver to follow the CEA specification wrt sending
of infoframes.
Since we only support the generation of AVI version 2, this limits us
to CEA extension version 3, so we treat CEA extension version 2 as
CEA 861 (no infoframes, no audio.)

Avoid a race between programming audio and an in-progress mode set.
A mode set is complex, and disables the ability to send infoframes
to the sink, and is disruptive to audio - we have to mute the audio
FIFO while doing a mode set.
If an attempt is made to start up the audio side, we will undo the
audio FIFO mute before the mode set has completed.
Move the lock so that we prevent audio interfering with an in-progress
mode set.

As priv->audio_params can now be changed at run time, we need to be more
careful about how we deal with a mode set. We must take the audio lock
while checking if there's a valid audio configuration.
However, it's slightly worse than that - during mode set, we mute the
audio, and it must not be unmuted until we have finished the mode set.
It is possible that the audio side may start while a mode set is in
progress, so take the audio_mutex lock around the whole mode setting
procedure.

Connectors shouldn't be registered until the rest of the whole device
is set up, so that consistent state is presented to userspace.
As such, remove the calls to drm_connector_register() and
drm_connector_unregister() from tda998x, as these are now handled by
drm_dev_(un)register() itself.
To work with this change, the mali-dp and hdlcd bind and unbind
sequences have to be reordered, to ensure that the componentised
encoder/connector is bound before drm_dev_register() registers all
connectors. Similarly, the device must be unregistered before the
component is unbound.
Altogether, this allows other drivers using tda998x to be
de-midlayered, and to have less racy initialisation of their components.
Splitting this commit into three (one per driver) isn't possible without
intermediate breakage, so it is all squashed together here.

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64). Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.
Note that only the modifier will be packed differently between compat
and non-compat versions.

drm/i915: Ignore OpRegion panel type except on select machines
Revert "drm/i915/psr: Make idle_frames sensible again"
drm/i915: Restore lost "Initialized i915" welcome message
Turns out
commit a05628195a ("drm/i915: Get panel_type from OpRegion panel
details") has regressed quite a few machines. So it looks like we
can't use the panel type from OpRegion on all systems, and yet we
absolutely must use it on some specific systems.
Despite trying, I was unable to find any automagic way to determine
if the OpRegion panel type is respectable or not. The only glimmer
of hope I had was bit 8 in the SCIC response, but that turned out to
not work either (it was always 0 on both types of systems).
So, to fix the regressions without breaking the machine we know to need
the OpRegion panel type, let's just add a quirk for this. Only specific
machines known to require the OpRegion panel type will therefore use
it. Everyone else will fall bck to the VBT panel type.
The only known machine so far is a "Conrac GmbH IX45GM2". The PCI
subsystem ID on this machine is just a generic 8086:2a42, so of no use.
Instead we'll go with a DMI match.
I suspect we can now also revert
commit aeddda06c1 ("drm/i915: Ignore panel type from OpRegion on SKL")
but let's leave that to a separate patch.
v2: Do the DMI match in the opregion code directly, as dev_priv->quirks
gets populated too late

drm/i915/psr: Make idle_frames sensible again
There are panels that needs 4 idle frames before entering PSR,
but VBT is unproperly set.
Also lately it was identified that idle frame count calculated at HW
can be off by 1, what makes the minimum of 2, at least.
Without the current vbt+1 we are with the risk of having HW calculating
0 idle frames and entering PSR when it shouldn't. Regardless the lack
of link training.
[Jani: there is some disagreement on the explanation, but the commit
regresses so revert it is.]

Register ASoC HDMI codec for audio functionality and adds device tree

With the registered HDMI codec the tda998x node can be used like a
regular codec node in ASoC card configurations. HDMI audio info-frame

also applies constraints for available sample-rates based on Edid Like

Even if PR3 support is available on the bridge, it will not be used if
the PCI layer considers it unavailable (i.e. on all laptops from 2013
and 2014). Ensure that this condition is checked to allow a fallback to
the Optimus DSM for device poweroff.
Initially I wanted to call pci_d3cold_enable before checking bridge_d3
(in case the user changed d3cold_allowed), but that is such an unlikely
case and likely fragile anyway. The current patch is suggested by Mika
in http://www.spinics.net/lists/linux-pci/msg52599.html

The intent was to make sure people don't sneak in a small immediate or
something to change the interpretation of the uniform update args, but
these signals are just fine.
Fixes a validation failure in the current X server on some Render
operation.

The atomic conversion lost the notification to let the DRM core
know about the current state of the CRTC vblank interrupts. This
regressed the ability of the core to reject page flip attempts
on currently disabled CRTCs. Add back the notifications.

We don't support configuring active plane on-the-fly for imx-drm.
The relevant CRTC should be disabled before the plane configuration.
Of course, the plane itself should be disabled as well.
This patch adds active plane reconfiguration support by forcing CRTC
mode change and disabling-enabling plane in plane's ->atomic_update
callback.
