ASoC: sunxi: Add the Allwinner A10 codec bindings 



The Allwinner SoCs have an in-SoC audio controller taking the role of a DAI
and a codec.

Add the binding documentation for that controller on the A10.

* 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";

};
