The value used to identify chip variant is not an enumeration, but raw
value used to compare registers with. The 'enum' is not used in the
code at all, so simplify and make it a raw hex value define, so
intention will be explicit.

Merge series from srinivas.kandagatla@linaro.org:
On Lenovo ThinkPad T14s, the headset is connected via a HiFi Switch to
support CTIA and OMTP headsets. This switch is used to minimise pop and
click during headset type switching.
This patchset adds required bindings and changes to codec and dts to
tnable the regulator required to power this switch along with wiring up
gpio that control the headset switching.
Without this patchset, there will be lots of noise on headset and mic
will not we functional.
Remove confusing and unused argument in swap_gnd_mic api, the second
argument active is not really used, and always set to true in the mbhc
drivers.
The callback itself is used to toggle the gnd_mic lines when a cross
connection is detected by mbhc circuits, so there is no need of this
argument.

of_gpio.h is deprecated, update the driver to use GPIO descriptors.
- Use dev_gpiod_get to get GPIO descriptor.
- Use gpiod_set_value to configure output value.
With legacy of_gpio API, the driver set gpio value 0 to assert reset,
and 1 to deassert reset. And the reset-gpios use GPIO_ACTIVE_LOW flag in
DTS, so set GPIOD_OUT_LOW when get GPIO descriptors, and set value 1 means
output low, set value 0 means output high with gpiod API.
The in-tree DTS files have the right polarity set up already so we
can expect this to "just work".

irq_domain_add_linear() is going away as being obsolete now. Switch to
the preferred irq_domain_create_linear(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. Therefore, of_fwnode_handle() is added around the
parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

Driver does not unregister typec structures (typec_mux_dev and
typec_switch_desc) during removal leading to leaks. Fix this by moving
typec registering parts to separate function and using devm interface to
release them. This also makes code a bit simpler:
- Smaller probe() function with less error paths and no #ifdefs,
- No need to store typec_mux_dev and typec_switch_desc in driver state
container structure.

In the wcd939x codec driver, there are two instances where semicolons
are used after closing braces of a switch-case statement. These
semicolons are not required and do not adhere to the coding style
guidelines.
This patch removes the unnecessary semicolons at the end of the
switch-case statements which cleans up the code and ensures consistency
with the rest of the kernel coding style.

Add the main WCD9390/WCD9395 Audio Codec driver to support:
- 4 ADC inputs for up to 5 Analog Microphones
- 4 DMIC inputs for up to 8 Digital Microphones
- 4 Microphone BIAS
- Stereo Headphone output
- Mono EAR output
- MBHC engine for Headset Detection
It makes usage of the generic MBHC and CLSH generic code and
the USB Type-C mux and switch helpers to gather USB-C Events
in order to properly setup Headset Detection mechanism
when connected behind the separate USB-C Mux subsystem.
WCD9390/WCD9395 supports a PCM path for Playback instead
of the actually implemented PDM playback, it will be
implemented later.
