AK4613 I2C transmitter
|
||||
|
||||
This device supports I2C mode only.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : "asahi-kasei,ak4613"
|
||||
- reg : The chip select number on the I2C bus
|
||||
|
||||
Example:
|
||||
|
||||
&i2c {
|
||||
ak4613: ak4613@0x10 {
|
||||
compatible = "asahi-kasei,ak4613";
|
||||
reg = <0x10>;
|
||||
};
|

};
