ASoC: Add support for GPIOs driven amplifiers
Herve Codina <herve.codina@bootlin.com> says:

On some embedded system boards, audio amplifiers are designed using
discrete components such as op-amp, several resistors and switches to
either adjust the gain (switching resistors) or fully switch the
audio signal path (mute and/or bypass features).

Those switches are usually driven by simple GPIOs.

This kind of amplifiers are not handled in ASoC and the fallback is to
let the user-space handle those GPIOs out of the ALSA world.

In order to have those kind of amplifiers fully integrated in the audio
stack, this series introduces the audio-gpio-amp to handle them.

This new ASoC component allows to have the amplifiers seen as ASoC
auxiliarty devices and so it allows to control them through audio mixer
controls.

In order to ease the review, I choose to split modifications related
to the merge of the gpio-audio-amp part into the simple-amplfier driver
in several commits.

74e8409821 ALSA: doc: cs35l56: Update path to HDA driver source
The HDA drivers were moved to sound/hda/... so update a Documentation
reference that still pointed to the old location.

ASoC: doc: cs35l56: Update firmware filename description for B0 silicon
Update the text for firmware file naming to show that the l?u? suffix is
supported on CS35L56 B0 silicon and ampN was only used on early firmware.

The previous version of this text only said that B0 silicon used the ampN
suffix. Since kernel 6.16 the driver supports both the old ampN and
new l?u? suffix for B0 silicon. New firmwares will use the l?u? suffix.

ASoC: doc: cs35l56: Update to add new SoundWire firmware filename suffix
Add the new firmware filename suffix used for SoundWire systems with
CS35L57, CS35L63 or CS35L56 later than B0 silicon. This uses the SoundWire
physical address of the amp to identify which firmware file to load on that
amp.
