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.

1 | * Allwinner A10 Codec | ||
2 | |||
3 | Required properties: | ||
4 | - compatible: must be either "allwinner,sun4i-a10-codec" or | ||
5 | "allwinner,sun7i-a20-codec" | ||
6 | - reg: must contain the registers location and length | ||
7 | - interrupts: must contain the codec interrupt | ||
8 | - dmas: DMA channels for tx and rx dma. See the DMA client binding, | ||
9 | Documentation/devicetree/bindings/dma/dma.txt | ||
10 | - dma-names: should include "tx" and "rx". | ||
11 | - clocks: a list of phandle + clock-specifer pairs, one for each entry | ||
12 | in clock-names. | ||
13 | - clock-names: should contain followings: | ||
14 | - "apb": the parent APB clock for this controller | ||
15 | - "codec": the parent module clock | ||
16 | - routing : A list of the connections between audio components. Each | ||
17 | entry is a pair of strings, the first being the connection's sink, | ||
18 | the second being the connection's source. | ||
19 | |||
