When I booted up on a board that had a slightly different codec
stuffed on it, I got this message at bootup:
rt5682 9-001a: Device with ID register 6749 is not rt5682
That's normal/expected, but what wasn't normal was the splat that I
got after:
WARNING: CPU: 7 PID: 176 at drivers/regulator/core.c:2151 _regulator_put+0x150/0x158

This is because the error paths don't turn off the regulator. Let's

ASoC: Fixes for v5.14
Quite a lot of fixes here, the biggest set being for the cs42l42 driver
which is reasonably old but has seen a sudden uptick in activity.
There's also some fixes for correctly referencing PCM buffer addresses
and the removal of some driver-local bodges that had been done for the
lack of prefix handling in DAPM which were broken by the core handling
that as expected.
If the machine driver doesn't call snd_soc_dai_set_sysclk() the
SCLK is assumed to be sample_rate * sample_bits * 2 (that is, the
rate necessary for a standard I2S frame).
But 24-bit samples can be sent in either a 24-bit slot or a 32-bit
slot. If the PLL is configured for a 24-bit slot, but a 32-bit slot is
used, cs42l42 will be overclocked.
Ultimately it is the machine driver's responsibilty to call
snd_soc_dai_set_sysclk() if SLK will be different from the standard
I2S rate. However, it is convenient to assume 32-bit slots to allow
this common case without needing special machine driver support. The
machine driver then only has to set SCLK if the slots are 24-bit, but
if it fails to do this cs42l42 won't be overclocked.

I2S always has two LRCLK phases and both CH1 and CH2 of the RX
must be enabled (corresponding to the low and high phases of LRCLK.)
The selection of the valid data channels is done by setting the DAC
CHA_SEL and CHB_SEL. CHA_SEL is always the first (left) channel,
CHB_SEL depends on the number of active channels.
Previously for mono ASP CH2 was not enabled, the result was playing
mono data would not produce any audio output.

The lowest valid SCLK corresponds to 44.1 kHz at 16-bit. Sample
rates less than this would produce SCLK below the minimum when using
a normal I2S frame. A constraint must be applied to prevent this.
The constraint is not applied if the machine driver sets SCLK, to
allow setups where the host generates additional bits per LRCLK
phase to increase the SCLK frequency. In these cases the machine
driver would always have to inform this driver of the actual SCLK,
and it must select a legal SCLK.

Both SCLK and PLL clocks must be running to drive the glitch-free mux
behind MCLK_SRC_SEL and complete the switchover.
This patch moves the writing of MCLK_SRC_SEL to when the PLL is started
and stopped, so that it only transitions while the PLL is running.
The unconditional write MCLK_SRC_SEL=0 in cs42l42_mute_stream() is safe
because if the PLL is not running MCLK_SRC_SEL is already 0.

The driver was defining two ALSA controls that both change the same
register field for the wind noise filter corner frequency. The filter
response has two corners, at different frequencies, and the duplicate
controls most likely were an attempt to be able to set the value using
either of the frequencies.
However, having two controls changing the same field can be problematic
and it is unnecessary. Both frequencies are related to each other so
setting one implies exactly what the other would be.
Removing a control affects user-side code, but there is currently no
known use of the removed control so it would be best to remove it now
before it becomes a problem.

The tlv320aic31xx driver relies on regcache_sync() to restore the register
contents after going to _BIAS_OFF, for example during system suspend. This
does not work for the jack detection configuration since that is configured
via the same register that status is read back from so the register is
volatile and not cached. This can also cause issues during init if the jack
detection ends up getting set up before the CODEC is initially brought out
of _BIAS_OFF, we will reset the CODEC and resync the cache as part of that
process.
Fix this by explicitly reapplying the jack detection configuration after
resyncing the register cache during power on.
This issue was found by an engineer working off-list on a product
kernel, I just wrote up the upstream fix.

and a Makefile trick links the wcd938x-sdw backend as built-in

ASoC: Fixes for v5.14
A collection of fixes for ASoC that have come in since the merge window,
all driver specific. There is a new core feature added for reversing
the order of operations when shutting down, this is needed to fix a bug
with the AMD Stonyridge platform, and we also tweak the Kconfig to make
the SSM2518 driver user selectable so it can be used with generic cards
but that requires no actual code changes.
To test the host controller and bus management code, it is currently
required to have a physical SoundWire peripheral attached to the
bus. To help with pre-silicon or early hardware enablement, it would
be very useful to have a SoundWire 'mockup' device that is exposed in
platform firmware but does not drive any signal on the bus.
This is different to the existing ASoC 'dummy' codec uses for I2S/TDM,
the SoundWire spec makes it clear that a device that is not attached
to the bus is not permitted to interact with the bus, be it for
command/control or data.
This patch exposes a 'mockup' device, with a minimalist driver, with 4
partID values reserved by Intel for such test configurations. The
mockup device exposes one full-duplex DAI based on 2 ports (DP1 for
playback and DP8 for capture). The capture data port is just virtual,
such a mockup device is prevented by the SoundWire specification from
presenting any data generated by a Source port without being Attached.
All the callbacks exposed by the SoundWire Slave interface are
populated, even if they just return immediately. This is intentional
to describe what a minimal codec driver should do and implement and
help new codec vendors provide support for their devices.
