AK4458 audio DAC
This device supports I2C mode.
Required properties:
- compatible : "asahi-kasei,ak4458"
- 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
Example:
&i2c {
ak4458: dac@10 {
compatible = "asahi-kasei,ak4458";
reg = <0x10>;
reset-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>
mute-gpios = <&gpio1 11 GPIO_ACTIVE_HIGH>
};
