AK4118 S/PDIF transceiver
This device supports I2C mode.
Required properties:
- compatible : "asahi-kasei,ak4118"
- reg : The I2C address of the device for I2C
- reset-gpios: A GPIO specifier for the reset pin
- irq-gpios: A GPIO specifier for the IRQ pin
Example:
&i2c {
ak4118: ak4118@13 {
#sound-dai-cells = <0>;
compatible = "asahi-kasei,ak4118";
reg = <0x13>;
reset-gpios = <&gpio 0 GPIO_ACTIVE_LOW>
irq-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
};
};
