The recent bug report suggests that BCLK setup for i915 HSW/BDW needs
to be updated at each HDMI hotplug, not only at initialization and
resume. That is, we need to update HSW_EM4 and HSW_EM5 registers at
ELD notification, too. Otherwise the HDMI audio may be out of sync
and played in a wrong pitch.
However, the HDA codec driver has no access to the controller
registers, and currently the code managing these registers is in
hda_intel.c, i.e. local to the controller driver. For allowing the
explicit BCLK update from the codec driver, as in this patch, the
former haswell_set_bclk() in hda_intel.c is moved to hdac_i915.c and
exposed as snd_hdac_i915_set_bclk(). This is called from both the HDA
controller driver and intel_pin_eld_notify() in HDMI codec driver.
Along with this change, snd_hdac_get_display_clk() gets dropped as
it's no longer used.

Although one weird behavior about the input path (inconsistent D0/D3
switch) on Cirrus CS420x codecs was fixed in the previous commit,
there is still an issue on some Mac machines: the capture stream
stalls when switching the ADCs on the fly. More badly, this keeps
stuck until the next reboot.
The dynamic ADC switching is already a bit fragile and assuming
optimistically that the chip accepts the frequent power changes. On
Cirrus codecs, this doesn't seem applicable.
As a quick workaround, we pin down the ADCs to keep up in D0 when
spec->dyn_adc_switch is set. In this way, the ADCs are kept up only
for the system that were confirmed to be broken.

The Optiplex 9020m with Haswell-DT processor needs a quirk for the
headset jack at the front of the machine to be able to use microphones.
A quirk for this model was originally added in 3127899, but c77900e
removed it in favour of a more generic version.
Unfortunately, pin configurations can changed based on firmware/BIOS
versions, and the generic version doesn't have any effect on newer
versions of the machine/firmware anymore.

We've got a regression report that the recording on Mac with a cirrus
codec doesn't work any longer. This turned out to be the missing
power up to D0 by power_save_node enablement.
After analyzing the traces, we found out that the culprit is that the
codec advertises the "actual" power state of a few nodes to be D0
while the "target" power state is D3. This inconsistency is usually
OK, as it implies the power transition. But in the case of cirrus
codec, this seems to be stuck to D3 while it's not actually D0.
This patch addresses the issue by checking the power state difference
more strictly. It sends the power-state change verb unless both the
target and the actual power states show the given value.
We may introduce yet another flag indicating the possible broken
hardware power state, but it's anyway safer to set the proper power
state even in a transition (at least it's harmless as long as the
target state is same). So this simpler change was applied now.

While the previous commit fixed the missing monitor_present flag
update, it may be still in an inconsistent state while the driver
repolls: the flag itself is updated, but the eld_valid flag and the
contents don't follow until the repoll finishes (and may be repeated
for a few times).
The basic problem is that pin_eld->monitor_present is updated in the
caller side. This should have been updated only in update_eld(). So,
the proper fix is to avoid accessing pin_eld but only spec->temp_eld.

The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI
monitor_present update] covered the missing update of monitor_present
flag, but this caused a regression for devices without the i915 eld
notifier. Since the old code supposed that pin_eld->monitor_present
was updated by the caller side, the hdmi_present_sense_via_verbs()
doesn't update the temporary eld->monitor_present but only
pin_eld->monitor_present, which is now overridden in update_eld().
The fix is to update pin_eld->monitor_present as well before calling
update_eld().
Note that this may still leave monitor_present flag in an inconsistent
state when the driver repolls, but this is at least the old behavior.
More proper fix will follow in the later patch.

i915 get_eld ops may return an error when no encoder is connected, and

The recent addition of on-demand i915 audio component binding in the
codec driver seems leading to the unbalanced i915 power refcount,
according to Intel CI tests. Typically, it gets a kernel WARNING
like:
WARNING: CPU: 3 PID: 173 at sound/hda/hdac_i915.c:91 snd_hdac_display_power+0xf1/0x110 [snd_hda_core]()

[<ffffffffa01192a6>] hda_codec_runtime_suspend+0x76/0xa0 [snd_hda_codec]
.....
The scenario is like below:
- HD-audio driver and i915 driver are probed concurrently at the
(almost) same time; HDA bus tries to bind with i915, but it fails
because i915 initialization is still being processed.
- Later on, HD-audio probes the HDMI codec, where it again tries to
bind with i915. At this time, it succeeds.
- At finishing the probe of HDA, it decreases the refcount as if it
were already bound at the bus probe, since the component is bound
now. This triggers a kernel WARNING due to the unbalance.
As a workaround, in this patch, we just disable the on-demand i915
component binding in the codec driver. This essentially reverts back
to the state of 4.4 kernel.
We know that this is no real solution, but it's a minimalistic simple
change that can be applied to 4.5.x kernel as stable.

snd_hdac_sync_audio_rate() call is mandatory only for HSW and later
models, but we call the function unconditionally blindly assuming that
the function doesn't do anything harmful. But since recently, the
function checks the validity of the passed pin NID, and eventually
spews the warning if an unexpected pin is passed. This is seen on old
chips like Baytrail.
The fix is to limit the call of this function again only for the chips
with the proper binding. This can be identified by the same flag as
the eld notifier.

The commit [b62232d429fa: ALSA: hda - Limit i915 HDMI binding only for
HSW and later] tried to limit the usage of i915 audio notifier to the
recent Intel models and switch to the old method on pre-Haswell
models. However, it assumed that the i915 component binding hasn't
been done on such models, and the assumption was wrong: namely,
Baytrail had already the i915 component binding due to powerwell
control. Thus, the workaround wasn't applied to Baytrail.
For fixing this properly, this patch introduces a new flag indicating
the usage of audio notifier and codec_has_acomp() refers to this flag
instead of checking the existence of audio component.

The recent change in HD-audio HDMI/DP codec driver for allowing the
dynamic PCM binding introduced a new spec->pcm_mutex. One of the
protected area by this mutex is hdmi_present_sense(). As reported by
Intel CI tests, unfortunately, the new mutex causes a deadlock when
the hotplug/unplug is triggered during the codec is in runtime
suspend. The buggy code path is like the following:
hdmi_unsol_event() -> ...
-> hdmi_present_sense()
==> ** here taking pcm_mutex
-> hdmi_present_sense_via_verbs()
-> snd_hda_power_up_pm() -> ... (runtime resume calls)
-> generic_hdmi_resume()
-> hdmi_present_sense()
==> ** here taking pcm_mutex again!
As we can see here, the problem is that the mutex is taken before
snd_hda_power_up_pm() call that triggers the runtime resume. That is,
the obvious solution is to move the power up/down call outside the
mutex; it is exactly what this patch provides.
The patch also clarifies why this bug wasn't caught beforehand. We
used to have the i915 audio component for hotplug for all Intel chips,
and in that code path, there is no power up required but the
information is taken directly from the graphics side. However, we
recently switched back to the old method for some old Intel chips due
to regressions, and now the deadlock issue is surfaced.

It turned out that the pre-HSW Intel chips are incompatible with the
naive assumption we had -- the fixed mapping between the port and the
HD-audio widget. This may result in the bad access, as captured by
the recent patch to add a WARN_ON() for the port mapping check.
As a quick workaround, disable the i915 audio component binding for
all pre-Haswell models.

Cirrus HD-audio driver may adjust GPIO pins for EAPD dynamically
depending on the jack plug state. This works fine for the auto-mute
mode where the speaker gets muted upon the HP jack plug. OTOH, when
the auto-mute mode is off, this turns off the EAPD unexpectedly
depending on the jack state, which results in the silent speaker
output.
This patch fixes the silent speaker output issue by setting GPIO bits
constantly when the auto-mute mode is off.

nvhdmi_chmap_cea_alloc_validate_get_type calls itself recursively
using chmap ops causing the double fault.
Fixed by adding the default validate_get_type handling inside nvdia

The current Intel HDMI codec driver supports only three fixed ports
from port B to port D. However, i915 driver may assign a DP on other
ports, e.g. port A, when no eDP is used. This incompatibility is
caught later at pin_nid_to_pin_index() and results in a warning
message like "HDMI: pin nid 4 not registered" at each time.
This patch filters out such invalid events beforehand, so that the
kernel won't be too grumbling.

Defer to register acomp eld notifier until hdmi audio driver
is fully ready.
After registering eld notifier, gfx driver can use this
callback function to notify audio driver the monitor
connection event. However this action may happen when
audio driver is adding the pins or doing other initialization.
This is not always safe, however. For example, using
per_pin->lock before the lock is initialized.
Let's register the eld notifier after the initialization is done.
