The Awinic AW8738 is a simple audio amplifier using a single GPIO.
The main difference to simple-amplifier is that there is a "one-wire
pulse control" that allows configuring the amplifier to one of a few
pre-defined modes. This can be used to configure the speaker-guard
function (primarily the power limit for the amplifier).

Add a simple driver that allows setting it up in the device tree
with a specified mode number.

The simple-mux driver requires gpiolib. Currently it selects GPIOLIB but
since the use of select can lead to issues with randconfig let's instead
depend on GPIOLIB, select is more idiomatically used for Kconfig symbols
that are not user selectable but GPIOLIB is user selectable.

Also, change the way CONFIG_SND_SOC_CS35L41 is

AK4375 is a 32-bit stereo DAC with headphones amplifier.
There's no documentation for it on akm.com, and only a brief
datasheet can be found floating on the internets [1].

Thanks to Oriane BAYERD <obayerd@eurocomposant.fr>
for finally answering my inquiries through akm.com, if only to tell
me that this chip is EOL following AKM factory burning in october 2020
and thus no detailed documentation is available anymore...

AK4331 is advertised [2] as pin and register compatible with AK4375
so some scraps of its datasheet were used and this driver might be
used as a base for it, but this is totally untested.

So this driver is mainly based on downstream code [3] and [4]
by Hu Jin from AKM (no known email).

Tested on msm8916-alcatel-idol347 and msm8939-alcatel-idol3,
which both use PLL driven clock with bypass of SRC (sample rate
converter), so only this setup is supported for now.

Work around this using two small hacks: An added Kconfig dependency
prevents the main driver from being built-in when soundwire support
itself is a loadable module to allow calling devm_regmap_init_sdw(),
and a Makefile trick links the wcd938x-sdw backend as built-in
if needed to solve the dependency between the two modules.

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.

There is no reason why the arizona core,irq and codec model specific
regmap bits cannot be build as a module. All they do is export symbols
which are used by the arizona-spi/i2c and arizona-codec modules, which
themselves can be built as module.

Change the Kconfig and Makefile arizona bits so that the arizona MFD-core
can be built as a module.

This is especially useful on x86 platforms with a WM5102 codec, this
allows the arizona MFD driver necessary for the WM5102 codec to be
enabled in generic distro-kernels without growing the base kernel-image
size.

Note this also adds an explicit "depends on MFD_ARIZONA" to all the
arizona codec Kconfig options. The codec drivers use functions from mfd
arizona-core. These new depends are necessary to disallow the codec
drivers being builtin when the arizona-core is build as a module,
otherwise we end up with missing symbol errors when building vmlinuz.
