-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";
- };
-};
