+Freescale i.MX audio complex with SGTL5000 codec
+
+Required properties:
+
+ - compatible : "fsl,imx-audio-sgtl5000"
+
+ - model : The user-visible name of this sound complex
+
+ - ssi-controller : The phandle of the i.MX SSI controller
+
+ - audio-codec : The phandle of the SGTL5000 audio codec
+
+ - 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 could be power supplies, SGTL5000
+ pins, and the jacks on the board:
+
+ Power supplies:
+ * Mic Bias
+
+ SGTL5000 pins:
+ * MIC_IN
+ * LINE_IN
+ * HP_OUT
+ * LINE_OUT
+
+ Board connectors:
+ * Mic Jack
+ * Line In Jack
+ * Headphone Jack
+ * Line Out Jack
+ * Ext Spk
+
+ - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
+
+ - mux-ext-port : The external port of the i.MX audio muxer
+
+Note: The AUDMUX port numbering should start at 1, which is consistent with
+hardware manual.
+
+Example:
+
+sound {
+ compatible = "fsl,imx51-babbage-sgtl5000",
+ "fsl,imx-audio-sgtl5000";
+ model = "imx51-babbage-sgtl5000";
+ ssi-controller = <&ssi1>;
+ audio-codec = <&sgtl5000>;
+ audio-routing =
+ "MIC_IN", "Mic Jack",
+ "Mic Jack", "Mic Bias",
+ "Headphone Jack", "HP_OUT";
+ mux-int-port = <1>;
+ mux-ext-port = <3>;
+};
