+* SiRF atlas6 and prima2 internal audio codec and port based audio setups
+
+Required properties:
+- compatible: "sirf,sirf-audio-card"
+- sirf,audio-platform: phandle for the platform node
+- sirf,audio-codec: phandle for the SiRF internal codec node
+
+Optional properties:
+- hp-pa-gpios: Need to be present if the board need control external
+ headphone amplifier.
+- spk-pa-gpios: Need to be present if the board need control external
+ speaker amplifier.
+- hp-switch-gpios: Need to be present if the board capable to detect jack
+ insertion, removal.
+
+Available audio endpoints for the audio-routing table:
+
+Board connectors:
+ * Headset Stereophone
+ * Ext Spk
+ * Line In
+ * Mic
+
+SiRF internal audio codec pins:
+ * HPOUTL
+ * HPOUTR
+ * SPKOUT
+ * Ext Mic
+ * Mic Bias
+
+Example:
+
+sound {
+ compatible = "sirf,sirf-audio-card";
+ sirf,audio-codec = <&audiocodec>;
+ sirf,audio-platform = <&audioport>;
+ hp-pa-gpios = <&gpio 44 0>;
+ spk-pa-gpios = <&gpio 46 0>;
