    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.
