+AK5558 8 channel differential 32-bit delta-sigma ADC
+
+This device supports I2C mode only.
+
+Required properties:
+
+- compatible : "asahi-kasei,ak5558"
+- reg : The I2C address of the device.
+
+Optional properties:
+
+- reset-gpios: A GPIO specifier for the power down & reset pin.
+
+Example:
+
+&i2c {
+ ak5558: adc@10 {
+ compatible = "asahi-kasei,ak5558";
+ reg = <0x10>;
+ reset-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>;
+ };
+};
