+* 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
+
+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";
+};
