+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>;
+	};
+};
