|
|
|
|
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@0x12 {
|
|
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";
