This driver supports both the I2C and SPI bus.

AK4613 I2C transmitter

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 {

		compatible = "asahi-kasei,ak4613";

		reg = <0x10>;

	};

};

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";

	};
