+AK5558 audio ADC
+
+This device supports I2C mode only.
+
+Required properties:
+
+- compatible : "asahi-kasei,ak5558"
+- reg : The I2C address of the device for I2C.
+- asahi-kasei,pdn-gpios: A GPIO specifier for the GPIO controlling
+ the power down & reset pin.
+
+Example:
+
+&i2c {
+ ak5558: ak5558@10 {
+ compatible = "asahi-kasei,ak5558";
+ reg = <0x10>;
+ asahi-kasei,pdn-gpios = <&gpio1 10 GPIO_ACTIVE_HIGH>;
+ };
+};
