Lenovo Thinkpad T440s suffers from constant background noises, and it
seems to be a generic hardware issue on this model:
https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T440s-speaker-noise/td-p/1339883
As the noise comes from the analog loopback path, disabling the path
is the easy workaround.
Also, the machine gives significant cracking noises at PM suspend. A
workaround found by trial-and-error is to disable the shutup callback
currently used for ALC269-variant.
This patch addresses these noise issues by introducing a new fixup
chain. Although the same workaround might be applicable to other
Thinkpad models, it's applied only to T440s (17aa:220c) in this patch,
so far, just to be safe (you chicken!). As a compromise, a new model
option string "tp440" is provided now, though, so that owners of other
Thinkpad models can test it more easily.

snd-hda-intel driver tries to bind with i915 audio component always
when AZX_DCAPS_I915_POWERWELL is set in the driver caps. This was
mostly OK in the past, as the flag was applied only to a limited set
of devices, namely, Haswell and Broadwell. On these machines, i915
graphics is almost mandatory as long as HDMI/DP is concerned.
Recently the application of i915 binding was widened to more Intel
chips. On these chips, the chance of a kernel without i915 graphics
is much higher, and such user would hit an error like:
snd_hda_intel 0000:00:1b.0: failed to add i915 component master (-19)
Although the error itself is harmless, it's certainly superfluous even
to try binding with i915, if we already know that there isn't any.
This patch fixes it by simply defining AZX_DCAPS_I915_POWERWELL as 0
in the case without i915. Then all codes referring to this flag will
be optimized out by the compiler.

The recent commit [6603249dcdbb: ALSA: hda - Enable audio component
for old Intel PCH devices] enabled the i915 binding for HDMI/DP on old
Intel PCHs. But many boards are without HDMI/DP, and they actually
don't need i915 binding, and yet the driver has a check of i915
binding and complains like
Haswell must be built with CONFIG_SND_HDA_I915
This error is false-positive, and it should be put only for HSW/BDW,
instead of all devices that may be bound with i915.
This patch fixes the condition to check, as well as rephrasing the
message specific to HSW/BDW HDMI/DP.

Many codecs, typically found on Realtek codecs, have the analog
loopback path merged to the secondary input of the middle of the
output paths. Currently, we don't offer the dynamic switching in such
configuration but let each loopback path mute by itself.
This should work well in theory, but in reality, we often see that
such a dead loopback path causes some background noises even if all
the elements get muted. Such a problem has been fixed by adding the
quirk accordingly to disable aamix, and it's the right fix, per se.
The only problem is that it's not so trivial to achieve it; user needs
to pass a hint string via patch module option or sysfs.
This patch gives a bit improvement on the situation: it adds "Loopback
Mixing" control element for such codecs like other codecs (e.g. IDT or
VIA codecs) with the individual loopback paths. User can turn on/off
the loopback path simply via a mixer app.
For keeping the compatibility, the loopback is still enabled on these
codecs. But user can try to turn it off if experiencing a suspicious
background or click noise on the fly, then build a static fixup later
once after the problem is addressed.
Other than the addition of the loopback enable/disablement control,
there should be no changes.

We have two latest thinkpad laptop models which are all based on the
Intel skylake platforms, and all of them have the codec alc293 on
them. When the machines boot to the desktop, an greeting dialogue
shows up with the notification sound. But on these two models, there
is noise with the notification sound. We have 3 SKUs for each of
the models, all of them have this problem.
So far, this problem is only specific to these two thinkpad models,
we did not find this problem on the old thinkpad models with the
codec alc293 or alc292.
A workaround for this problem is disabling the aamix.

rme96 driver needs to reset DAC depending on the sample rate, and this
results in resetting to the max volume suddenly. It's because of the
missing call of snd_rme96_apply_dac_volume().
However, calling this function right after the DAC reset still may not
work, and we need some delay before this call. Since the DAC reset
and the procedure after that are performed in the spinlock, we delay
the DAC volume restore at the end after the spinlock.

As i915 graphics driver provides the notification via audio component,
not only the currently implemented HSW+ and VLV+ platforms but also
all other PCH-based platforms (e.g. Cougar Point, Panther Point, etc)
can use this infrastructure. It'll improve the reliability and the
power consumption significantly, especially once when we implement the
ELD notification via component. As a preliminary, this patch enables
the usage of audio component for all PCH platforms.
The HDA controller just needs to set AZX_DCAPS_I915_POWERWELL flag
appropriately. The name of the flag is a bit confusing, but this
actually works even on the chips without the powerwell but accesses
only the other component ops.
In the HDMI/DP codec driver side, we just need to register/unregister
the notifier for such chips. This can be identified by checking the
audio_component field in the assigned hdac_bus.
One caveat is that PCH for Haswell and Broadwell must not be bound
with i915 audio component, as there are dedicated HD-audio HDMI
controllers on these platforms. Ditto for Poulsbo and Oaktrail as
they use gma500 graphics, not i915.

The ELD notification can be received asynchronously from the graphics
side, and this may happen just at the moment the sound driver is
processing the suspend or the resume, and it would confuse the whole
procedure. Since the ELD and connection states are updated in anyway
at the end of the resume, we can skip it when received during PM
process.

The recent addition of ELD notifier for Intel HDMI/DP codec may lead
the bad codec connection found as kernel messages like below:
Suspending console(s) (use no_console_suspend to debug)
hdmi_present_sense: snd_hda_codec_hdmi hdaudioC0D2: HDMI status: Codec=2 Pin=6 Presence_Detect=1 ELD_Valid=1
snd_hda_intel 0000:00:1f.3: spurious response 0x0:0x2, last cmd=0x206f2e08
snd_hda_intel 0000:00:1f.3: spurious response 0x0:0x2, last cmd=0x206f2e08
....
snd_hda_codec_hdmi hdaudioC0D2: HDMI: ELD buf size is 0, force 128
snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to polling mode: last cmd=0x206f2f00
snd_hda_intel 0000:00:1f.3: No response from codec, disabling MSI: last cmd=0x206f2f00
snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to single_cmd mode: last cmd=0x206f2f00
azx_single_wait_for_response: 42 callbacks suppressed
This seems appearing when the sound driver went to suspend before i915
driver. Then i915 driver disables HDMI/DP audio bit and calls the
registered notifier, and the HDA codec tries to handle it as a
hot(un)plug. But since the driver is already in the suspended state,
it fails miserably.
As this is a sort of spurious wakeup, it can be ignored safely, as
long as it's delivered during the system suspend. OTOH, if a
notification comes during the runtime suspend, the situation is
different: we need to wake up. But during the system suspend, such a
notification can't be the reason for a wakeup.
This patch addresses it by a simple check of the current sound card
status. The skipped notification doesn't matter because the HDA
driver will check the plugged status forcibly at the resume in
return.
Then, why the card status, not a runtime PM status or else? The HDA
controller driver is supposed to set the card status to D3 at the
system suspend but not at the runtime suspend. So we can see it as a
flag that is set only for the system suspend. Admittedly, it's a bit
ugly, but it should work well for now.

- Reset the DAPM cache when freeing widgets to fix a crash on driver

The PM functions for nau8825 are new code which fix crashes on resume.

It turned out that many HP laptops suffer from the same problem as
fixed in commit [c932b98c1e47: ALSA: hda - Apply pin fixup for HP
ProBook 6550b]. But, it's tiresome to list up all such PCI SSIDs, as
there are really lots of HP machines.
Instead, we do a bit more clever, try to check the supposedly dock and
built-in headphone pins, and apply the fixup when both seem valid.
This rule can be applied generically to all models using the same
quirk, so we'll fix all in a shot.

The HDMI codec parser may create a phantom jack, but the helper
function snd_hda_jack_add_kctl() treats always as a normal jack. This
is superfluous as the jack query is executed at each time the jack
sync is performed.
Since the HDMI codec parser is the only caller of this function, it's
easier to change back this directly calling the original
__snd_hda_jack_add_kctl() with phantom_jack parameter.

snd_cs46xx_suspend() is missing snd_pcm_suspend_all calls for pcm_rear,
pcm_center_lfe and pcm_iec958.
There's also a copy/paste bug in snd_cs46xx_pcm_iec958(), overwriting
pcm_rear in struct snd_cs46xx, leaving pcm_iec958 unused.
Fix all this to allow all channels to survive suspend/resume.

Currently, the Duplicate front control is enabled only for two specific
revisions of CS4294.
Enable it for all CS4294 and CS4298 codecs instead.
This fixes rear output on my VC-4620N sound card
(CS4620 + CS4298 rev.5).

We've had many reports that some Creative sound cards with CA0132
don't work well. Some reported that it starts working after reloading
the module, while some reported it starts working when a 32bit kernel
is used. All these facts seem implying that the chip fails to
communicate when the buffer is located in 64bit address.
This patch addresses these issues by just adding AZX_DCAPS_NO_64BIT
flag to the corresponding PCI entries. I casually had a chance to
test an SB Recon3D board, and indeed this seems helping.
Although this hasn't been tested on all Creative devices, it's safer
to assume that this restriction applies to the rest of them, too. So
the flag is applied to all Creative entries.

This machine had I2S codec for speaker output.
It need to refill the I2S codec initial verb after resume back.

Use codec_*() macro instead of pr_*() for improving the log
information. The current form even slips from alsa-info.sh.
