+Ingenic JZ4725B codec controller
+
+Required properties:
+- compatible : "ingenic,jz4725b-codec"
+- reg : codec registers location and length
+- clocks : phandle to the AIC clock.
+- clock-names: must be set to "aic".
+- #sound-dai-cells: Must be set to 0.

+Example:
+
+codec: audio-codec@100200a4 {
+ compatible = "ingenic,jz4725b-codec";
+ reg = <0x100200a4 0x8>;
+
+ #sound-dai-cells = <0>;
+
+ clocks = <&cgu JZ4725B_CLK_AIC>;
+ clock-names = "aic";
