Add support for IIO devices in ASoC
Merge series from Herve Codina <herve.codina@bootlin.com>:
Several weeks ago, I sent a series [1] for adding a potentiometer as an
auxiliary device in ASoC. The feedback was that the potentiometer should
be directly handled in IIO (as other potentiometers) and something more
generic should be present in ASoC in order to have a binding to import
some IIO devices into sound cards.
The series related to the IIO potentiometer device is already applied.
This series introduces audio-iio-aux. Its goal is to offer the binding
between IIO and ASoC.
It exposes attached IIO devices as ASoC auxiliary devices and allows to
control them through mixer controls.
On my system, the IIO device is a potentiometer and it is present in an
amplifier design present in the audio path.
