- audio-gain-db : audio gain selection for external analog modulation input.
Valid values: 0 - 21, step by 3 (rounded down)
Default: 0
- shutdown-gpios : Specifier of the GPIO connected to SDB pin of the chip.
Each led is represented as a sub-node of the issi,is31fl319x device.
There can be less leds subnodes than the chip can support but not more.
