13  The AW2013 is a 3-channel LED driver with I2C interface. It can control
14  LED brightness with PWM output.

26      Used to report completion of operations (power up, LED breath effects).

31  vio-supply:
32    description: Regulator providing power for pull-up of the I/O lines.
33      "VIO1" in the typical application circuit example of the datasheet.
34      Note that this regulator does not directly connect to AW2013, but is
35      needed for the correct operation of the interrupt and I2C lines.
