   12 description:
   13   The Awinic AW8738 is a simple audio amplifier with different operation modes
   14   (set using one-wire pulse control). The mode configures the speaker-guard
   15   function (primarily the power limit for the amplifier).

   26       GPIO used for one-wire pulse control. The pin is typically called SHDN

   28       just a simple shutdown/enable control.
