-This device supports I2C mode only.
-
-Required properties:
-
-- compatible : "asahi-kasei,ak4613"
-- reg : The chip select number on the I2C bus
-
-Optional properties:
-- asahi-kasei,in1-single-end : Boolean. Indicate input / output pins are single-ended.
-- asahi-kasei,in2-single-end rather than differential.
-- asahi-kasei,out1-single-end
-- asahi-kasei,out2-single-end
-- asahi-kasei,out3-single-end
-- asahi-kasei,out4-single-end
-- asahi-kasei,out5-single-end
-- asahi-kasei,out6-single-end

-Example:
-
-&i2c {
- ak4613: ak4613@10 {
