+  - atmel,model: The user-visible name of this sound complex.
+  - atmel,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 WM8904's pins, and the jacks on the board:

+    * IN2L
+    * IN2R
+    * IN3L
+    * IN3R

+    * LINEOUTL
+    * LINEOUTR
+    * MICBIAS
+

+  - atmel,ssc-controller: The phandle of the SSC controller
+  - atmel,audio-codec: The phandle of the WM8904 audio codec
