Follow the example of Intel Atom drivers and keep a reference to the
headset codec until the properties are removed.
There is no guarantee that the module for the codec driver is loaded
before the machine driver probe, the use of the deferred probe
mechanism is required.

Two of three machine drivers using this search don't deal with errors

make sense here: an alternate driver will not be probed.

In current ACPI-based devices, the DSDT does not include any of the
properties required by the codec driver. This is not an ACPI
limitation proper since the _DSD method could be used, as done for
Camera and SoundWire in newer platforms. For legacy devices, there is
unfortunately no other option than using a work-around: we add
properties to the codec device from the machine driver.
To avoid any issues with the codec driver being unbound, we need to
keep a reference to the codec device until the card is removed.

ASoC: cs42l42: Assume 24-bit samples are in 32-bit slots
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.

ASoC: rt5640: Silence warning message about missing interrupt
Interrupt is optional for the RT5640 codec. Nexus 7 doesn't use interrupt,
this results in a noisy warning message that looks like a error condition.
Make interrupt explicitly optional to silence the message, use modern
IRQF_NO_AUTOEN flag and correct the reg[q]uest typo in the message.
ASoC: codecs: wcd938x: add Multi Button Headset Control support
WCD938x has Multi Button Headset Control hardware to support Headset
insertion, type detection, 8 headset buttons detection, Over Current
detection and Impedence measurements.
This patch adds support for this using wcd-mbhc apis.
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.
ASoC: cs42l42: Constrain sample rate to prevent illegal SCLK
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.
An I2S frame starts on the falling edge of LRCLK so ASP_STP must
be 0.
At the same time, move other format settings in the same register
from cs42l42_pll_config() to cs42l42_set_dai_fmt() where you'd
expect to find them, and merge into a single write.
ASoC: cs42l42: PLL must be running when changing MCLK_SRC_SEL
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.

ASoC: cs42l42: Remove duplicate control for WNF filter frequency
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 previous Kconfig cleanup added simplifications but also introduced
a new one by moving a boolean to a tristate. This leads to randconfig
problems.
This patch moves the select operations in the SOUNDWIRE_LINK_BASELINE
option. The INTEL_SOUNDWIRE config remains a tristate for backwards
compatibility with older configurations but is essentially an on/off

An I2S frame always has a left and right channel slot even if mono
data is being sent. So if channels==1 the actual bitclock frequency
is 2 * snd_soc_params_to_bclk(params).
ASoC: cs42l42: Correct definition of ADC Volume control
The ADC volume is a signed 8-bit number with range -97 to +12,
with -97 being mute. Use a SOC_SINGLE_S8_TLV() to define this
and fix the DECLARE_TLV_DB_SCALE() to have the correct start and
mute flag.

Hi Mark
Now I'm posting audio-graph-card2 patch-set, but it seems it needs longer
discussion. Thus I want to post more easy patch first, and reduce my
local patches.
These are cppcheck warning cleanup patches for soc-core.
