Currently each channel is added as list to dai channel list, however
there is danger of adding same channel to multiple dai channel list
which endups corrupting the other list where its already added.
This patch ensures that the channel is actually free before adding to
the dai channel list and also ensures that the channel is on the list
before deleting it.
This check was missing previously, and we did not hit this issue as
we were testing very simple usecases with sequence of amixer commands.

Commit 0454422288 ("ASoC: codecs: wcd938x: add audio routing and
Kconfig") adds SND_SOC_WCD937X, which does not exist, and
SND_SOC_WCD938X, which seems not really to be the intended config to be
selected, but only a supporting config symbol to the actual config
SND_SOC_WCD938X_SDW for the codec.
Add SND_SOC_WCD938_SDW to the list instead of SND_SOC_WCD93{7,8}X.
The issue was identified with ./scripts/checkkconfigsymbols.py.

Higher speeds are only supported when PLL is enabled, but
the current driver doesn't enable PLL outside of stream
use cases, so better to set the lowest SPI speed accepted
by the entire device.
Move the current frequency set to the spi sub-driver so
the whole device can benefit from that speed.
spi-max-frequency property could be used, but ACPI systems don't
support it, so by setting it in the spi sub-driver probe
both Device Trees and ACPI systems are supported.

Merge series from Ariel D'Alessandro <ariel.dalessandro@collabora.com>:
This patchset modifies the tlv320aic31xx driver to update its sysclk if
BCLK is used as the input clock. This allows to be used by the generic
fsl-asoc-card, without having to add a specific driver.
When a jack handler is registered in cs42l42_set_jack() the
initial state should be reported if an attached headphone/headset
has already been detected.
The jack detect sequence takes around 1 second: typically long
enough for the machine driver to probe and register the jack handler
in time to receive the first report from the interrupt handler. So
it is possible on some systems that the correct initial state was seen
simply because of lucky timing. Modular builds were more likely to
miss the reporting of the initial state.

When reporting a jack unplug there's no need to make the reported
flags conditional on which flags were reported during the plug
event. It's perfectly safe to report all flags and buttons as
not-present and let the higher code filter for changes.
There's also no need to make two separate snd_soc_jack_report()
calls for presence flags and button flags. It can all be done in
one report.

There are multiple places where DETECT_MODE is included in a register
write, but in every case it is written as 0. Removing these redundant
writes makes the code less cluttered and also makes it obvious that
DETECT_MODE is never changed.
A single initialization to 0 is added to cs42l42_setup_hs_type_detect().

Interrupt Clear registers WCD938X_INTR_CLEAR_0 - WCD938X_INTR_CLEAR_2
are not marked as volatile. This has resulted in a missing interrupt bug
while performing runtime pm. regcache_sync() during runtime pm resume path
will write to Interrupt clear registers with previous values which basically
clears the pending interrupt and actual interrupt handler never sees this
interrupt.
This issue is more visible with headset plug-in plug-out case compared to
headset button.
Fix this by adding the Interrupt clear registers to volatile range

Revert 'I2S Reference' to SOC_ENUM_EXT because the settings are specific
for some platforms, the default setting for 'I2S Reference' does nothing,
only some SoC platform need to configure it.
Previous 'I2S Reference' in SOC_ENUM format only toggles one bit of
RT1011_TDM1_SET_1 register, which isn't enough for specific platform.

updates for various reported things, and some good cleanups. These
include:
- more good tty api cleanups from Jiri
- stm32 serial driver updates
- softlockup fix for non-preempt systems under high serial load
- rpmsg serial driver update
- 8250 drivers updates and fixes
- n_gsm line discipline fixes and updates as people are finally
