AK4458 audio DAC



This device supports I2C mode.



Required properties:



- compatible : "asahi-kasei,ak4458" or "asahi-kasei,ak4497"

- 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

- AVDD-supply: Analog power supply

- DVDD-supply: Digital power supply

- dsd-path: Select DSD input pins for ak4497

            0: select #16, #17, #19 pins

            1: select #3, #4, #5 pins



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>

	};

};
