 * Freescale MXS audio complex with SGTL5000 codec
 
 Required properties:
-- compatible: "fsl,mxs-audio-sgtl5000"
-- model: The user-visible name of this sound complex
-- saif-controllers: The phandle list of the MXS SAIF controller
-- audio-codec: The phandle of the SGTL5000 audio codec
+- compatible		: "fsl,mxs-audio-sgtl5000"
+- model			: The user-visible name of this sound complex
+- saif-controllers	: The phandle list of the MXS SAIF 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:

+
+			  SGTL5000 pins:
+			   * MIC_IN
+			   * LINE_IN
+			   * HP_OUT

+
+			  Board connectors:
+			   * Mic Jack
+			   * Line In Jack
+			   * Headphone Jack
+			   * Line Out Jack
+			   * Ext Spk
