This is because HDA is still in D0 state after freeze() call and

It seems bios still access HDA when system enter into freeze state,
HDA will receive codec response interrupt immediately after thaw() call.

Lenovo Thinkpads with Realtek codecs may still have some loud
crackling noises at reboot/shutdown even though a few previous fixes
have been applied. It's because the previous fix (disabling the
default shutup callback) takes effect only at transition of the codec
power state. Meanwhile, at reboot or shutdown, we don't take down the
codec power as default, thus it triggers the same problem unless the
codec is powered down casually by runtime PM.
This patch tries to address the issue. It gives two things:
- implement the separate reboot_notify hook to struct alc_spec, and
call it optionally if defined.
- turn off the codec to D3 for Thinkpad models via this new callback

Intel Atom processors seem to have a problem at recording when
bdl_pos_adj is set to an odd value. When a value like 1 is used, it
may drop the samples unexpectedly. Actually, for the old Atoms, we
used to set AZX_DRIVER_SCH type, and this assigns 32 as default.
Meanwhile the newer chips, Baytrail and Braswell, are set as
AZX_DRIVER_PCH, and the lower default value, 1, is assigned.
This patch changes the default values for these chipsets to a safer
default, 32, again. Since changing the driver type (AZX_DRIVER_XXX)
leads to the rename of the driver string, it would result in a
possible regression. So, we can't change the type. Instead, in this
patch, manual (ugly) PCI ID checks are added on top.
A drawback by this increase is the slight increase of the latency, but
it's a sub-ms order in normal situations, so mostly negligible.

Since we have a new audio component ops to fetch the current ELD and
state now, we can reduce the usage of unsol event of HDMI/DP pins.
The unsol event isn't only unreliable, but it also needs the power
up/down of the codec and link at each time, which is a significant
power and time loss.
In this patch, the jack creation and unsol/jack event handling are
modified to use the audio component for the dedicated Intel chips.
The jack handling got slightly more codes than a simple usage of
hda_jack layer since we need to deal directly with snd_jack object;
the hda_jack layer is basically designed for the pin sense read and
unsol events, both of which aren't used any longer in our case.

Due to the recent change, HDA controller driver for Intel PCH tries to
bind i915 audio component always at the probe time no matter whether
HDMI/DP codec is found. This is, however, superflulous for old
chipsets (e.g. on IVB) where they don't have always the HDMI/DP codecs
but often have only a discrete GPU instead.
For the newer chipsets, we need already the i915 binding from the
beginning due to power well control. Meanwhile, for older chipsets
where we don't need power well, we don't need the i915 binding at the
controller level.
This patch removes again the i915 binding in the HDA controller driver
for old Intel PCHs, but adds the binding in HDMI/DP codec driver
instead. This allows still the use of the direct notification from
the graphics driver while we can avoid the unnecessary load of i915
driver for machines only with another GPU.

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

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.

instead of all devices that may be bound with i915.

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.

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 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

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.
