-This device supports I2C mode.
-
-Required properties:
-
-- compatible : "asahi-kasei,ak4458" or "asahi-kasei,ak4497"
-- reg : The I2C address of the device for I2C
-
-Optional properties:
-- reset-gpios: A GPIO specifier for the power down & reset pin
-- mute-gpios: A GPIO specifier for the soft mute pin
-- AVDD-supply: Analog power supply
