+NVIDIA Tegra audio complex
+
+Required properties:
+- compatible : "nvidia,tegra-audio-alc5632"
+- nvidia,model : The user-visible name of this sound complex.
+- nvidia,audio-routing : A list of the connections between audio components.
+ Each entry is a pair of strings, the first being the connection's sink,
+ the second being the connection's source. Valid names for sources and
+ sinks are the ALC5632's pins:
+
+ ALC5632 pins:
+
+ * SPK_OUTP
+ * SPK_OUTN
+ * HP_OUT_L
+ * HP_OUT_R
+ * AUX_OUT_P
+ * AUX_OUT_N
+ * LINE_IN_L
+ * LINE_IN_R
+ * PHONE_P
+ * PHONE_N
+ * MIC1_P
+ * MIC1_N
+ * MIC2_P
+ * MIC2_N
+ * MICBIAS1
+
+ Board connectors:
+
+ * Headset Stereophone
+ * Int Spk
+ * Headset Mic
+
+- nvidia,i2s-controller : The phandle of the Tegra I2S controller
+- nvidia,audio-codec : The phandle of the ALC5632 audio codec
+
+Example:
+
+sound {
+ compatible = "nvidia,tegra-audio-alc5632-paz00",
+ "nvidia,tegra-audio-alc5632";
+
+ nvidia,model = "Compal PAZ00";
+
+ nvidia,audio-routing =
+ "Int Spk", "SPK_OUTP",
+ "Int Spk", "SPK_OUTN",
+ "Headset Mic","MICBIAS1",
+ "MIC1_N", "Headset Mic",
+ "MIC1_P", "Headset Mic",
+ "Headset Stereophone", "HP_OUT_R",
+ "Headset Stereophone", "HP_OUT_L";
+
+ nvidia,i2s-controller = <&tegra_i2s1>;
+ nvidia,audio-codec = <&alc5632>;
