AK4458 audio DAC
|
||||
|
||||
This device supports both I2C and SPI modes.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : "asahi-kasei,ak4458"
|
||||
- reg : The I2C address of the device for I2C, the chip select number for SPI.
|
||||
- asahi-kasei,pdn-gpios: A GPIO specifier for the GPIO controlling
|
||||
the power down & reset pin.
|
||||
- asahi-kasei,mute-gpios: A GPIO specifier for the GPIO controlling
|
||||
the soft mute pin.
|
||||
|
||||
Example:
|
||||
|
||||
&i2c {
|
||||
ak4458: ak4458@10 {
|
||||
compatible = "asahi-kasei,ak4458";
|
||||
reg = <0x10>;
|
||||
asahi-kasei,pdn-gpios = <&gpio1 10 GPIO_ACTIVE_HIGH>
|
||||
asahi-kasei,mute-gpios = <&gpio1 11 GPIO_ACTIVE_HIGH>
|
||||
};
|
||||
};
