ASoC: dt-bindings: Add schema for "awinic,aw8738"

Browse source

Add a DT schema for describing Awinic AW8738 audio amplifiers. They are
fairly simple and controlled using a single GPIO. The number of pulses
during power up selects one of a few pre-defined operation modes. This
can be used to configure the speaker-guard function (primarily the
power limit for the amplifier).
