AK4642 I2C transmitter
This device supports I2C mode only.
Required properties:
- compatible : "asahi-kasei,ak4642" or "asahi-kasei,ak4643" or "asahi-kasei,ak4648"
- reg : The chip select number on the I2C bus
Optional properties:
- #clock-cells : common clock binding; shall be set to 0
- clocks : common clock binding; MCKI clock
- clock-frequency : common clock binding; frequency of MCKO
- clock-output-names : common clock binding; MCKO clock name
Example 1:
&i2c {
ak4648: ak4648@12 {
compatible = "asahi-kasei,ak4642";
reg = <0x12>;
};
};
Example 2:
&i2c {
ak4643: codec@12 {
compatible = "asahi-kasei,ak4643";
reg = <0x12>;
#clock-cells = <0>;
clocks = <&audio_clock>;
clock-frequency = <12288000>;
clock-output-names = "ak4643_mcko";
};
};
