AK4613 I2C transmitter

This device supports I2C mode only.

Required properties:

- compatible : "asahi-kasei,ak4613"

- reg : The chip select number on the I2C bus

Example:

&i2c {

	ak4613: ak4613@0x10 {

		compatible = "asahi-kasei,ak4613";

		reg = <0x10>;

	};

};

  - compatible : "asahi-kasei,ak4642" or "asahi-kasei,ak4643" or "asahi-kasei,ak4648"

  - reg : The chip select number on the I2C bus

Example:

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 {

		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";

	};

};

- compatible			: "renesas,rcar_sound-<soctype>", fallbacks

				  "renesas,rcar_sound-gen1" if generation1, and

				  "renesas,rcar_sound-gen2" if generation2

				  "renesas,rcar_sound-gen3" if generation3

				  Examples with soctypes are:

				    - "renesas,rcar_sound-r8a7778" (R-Car M1A)

				    - "renesas,rcar_sound-r8a7790" (R-Car H2)

				    - "renesas,rcar_sound-r8a7791" (R-Car M2-W)

				    - "renesas,rcar_sound-r8a7795" (R-Car H3)

- reg				: Should contain the register physical address.

				  required register is

				   SRU/ADG/SSI      if generation1

- rcar_sound,dai		: DAI contents.

				  The number of DAI subnode should be same as HW.

				  see below for detail.

- #sound-dai-cells		: it must be 0 if your system is using single DAI

				  it must be 1 if your system is using multi  DAI

- #clock-cells			: it must be 0 if your system has audio_clkout

				  it must be 1 if your system has audio_clkout0/1/2/3

- clock-frequency		: for all audio_clkout0/1/2/3

SSI subnode properties:

- interrupts			: Should contain SSI interrupt for PIO transfer

* Allwinner A10 Codec

Required properties:

- compatible: must be either "allwinner,sun4i-a10-codec" or

  "allwinner,sun7i-a20-codec"

- reg: must contain the registers location and length

- interrupts: must contain the codec interrupt

- dmas: DMA channels for tx and rx dma. See the DMA client binding,

	Documentation/devicetree/bindings/dma/dma.txt

- dma-names: should include "tx" and "rx".

- clocks: a list of phandle + clock-specifer pairs, one for each entry

  in clock-names.

- clock-names: should contain followings:

   - "apb": the parent APB clock for this controller

   - "codec": the parent module clock

- routing : A list of the connections between audio components.  Each

  entry is a pair of strings, the first being the connection's sink,

  the second being the connection's source.

Example:

codec: codec@01c22c00 {

	#sound-dai-cells = <0>;

	compatible = "allwinner,sun7i-a20-codec";

	reg = <0x01c22c00 0x40>;

	interrupts = <0 30 4>;

	clocks = <&apb0_gates 0>, <&codec_clk>;

	clock-names = "apb", "codec";

	dmas = <&dma 0 19>, <&dma 0 19>;

	dma-names = "rx", "tx";

	routing = "Headphone Jack", "HP Right",

		  "Headphone Jack", "HP Left";

};

TDM slot properties:

dai-tdm-slot-num : Number of slots in use.

dai-tdm-slot-width : Width in bits for each slot.

dai-tdm-slot-tx-mask : Transmit direction slot mask, optional

dai-tdm-slot-rx-mask : Receive direction slot mask, optional

For instance:

	dai-tdm-slot-num = <2>;

	dai-tdm-slot-width = <8>;

	dai-tdm-slot-tx-mask = <0 1>;

	dai-tdm-slot-rx-mask = <1 0>;

And for each spcified driver, there could be one .of_xlate_tdm_slot_mask()

to specify a explicit mapping of the channels and the slots. If it's absent

For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit

for an active slot as default, and the default active bits are at the LSB of

the masks.

The explicit masks are given as array of integers, where the first

number presents bit-0 (LSB), second presents bit-1, etc. Any non zero

number is considered 1 and 0 is 0. snd_soc_of_xlate_tdm_slot_mask()

does not do anything, if either mask is set non zero value.
