-AK5558 8 channel differential 32-bit delta-sigma ADC
-
-This device supports I2C mode only.
-
-Required properties:
-
-- compatible : "asahi-kasei,ak5558" or "asahi-kasei,ak5552".
-- reg : The I2C address of the device.
-
-Optional properties:
-
-- reset-gpios: A GPIO specifier for the power down & reset pin.
-- AVDD-supply: Analog power supply
-- DVDD-supply: Digital power supply

-Example:
-
-&i2c {
-	ak5558: adc@10 {
-		compatible = "asahi-kasei,ak5558";
-		reg = <0x10>;
-		reset-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>;
