+SiRF SoC audio modules
+
+The audio modules inside the consist of an internal audio codec, internal
+audio port and i2s controller
+
+Required properties:
+- compatible: Must be "sirf,audio"
+- reg : The register address of the device
+- #address-cells: Must be 1
+- #size-cells: Must be 1
+
+Nodes:
+Internal audio codec:
+ - compatible : "sirf,atlas6-audio-codec" or "sirf,prima2-audio-codec"
+ - clocks: A phandle reference to the SiRF internal audio codec clock
+
+Internal audio port:
+- compatible: "sirf,audio-port"
+
+I2S controller:
+- compatible: "sirf,prima2-i2s"
+- clocks: A phandle reference to the SiRF I2S controller clock
+
+Example:
+sirfaudio: sirfaudio@b0040000 {
+ compatible = "sirf,atlas6-audio";
+ reg = <0xb0040000 0x10000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ audiocodec: audiocodec {
+ compatible = "sirf,atlas6-audio-codec";
+ interrupts = <35>;
+ clocks = <&clks 27>;
+ };
+
+ audioport: audioport {
+ compatible = "sirf,audio-port";
+ dmas = <&dmac1 3>, <&dmac1 8>;
+ dma-names = "rx", "tx";
+ };
+
+ i2s: i2s {
+ compatible = "sirf,prima2-i2s";
+ dmas = <&dmac1 6>, <&dmac1 12>;
+ dma-names = "rx", "tx";
+ clocks = <&clks 27>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&i2s_pins_a>;
+ };
+};
