+  - compatible		: Compatible list, contains "fsl,imx-audmix"
+
+  - model		: Short audio card description.
+
+  - dais		: Must contain a list of phandles to AUDMIX connected
+			  DAIs. The current implementation requires two phandles
+			  to SAI interfaces to be provided, the first SAI in the
+			  list being used to route the AUDMIX output.

.
