Some LEDs controllers are used with external pull-up for the interrupt line and the I2C lines, so we might need to enable a regulator to bring the lines into usable state. Otherwise, this might cause spurious interrupts and reading from I2C will fail. Document support for "vddio-supply" that is enabled by the aw2013 driver so that the regulator gets enabled when needed.
