+NXP Audio Mixer (AUDMIX) machine driver.
+
+Required properties:
+===================================
+  - 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.
+
+  - audmix-controller	: Must contain the phandle to the AUDMIX device node.
+
+Machine driver configuration example:
+====================================
+  sound-audmix-sai {
+    compatible = "fsl,imx-audmix";
+    model = "audmix-sai";
+    dais = <&sai4>, <&sai5>;
+    audmix-controller = <&audmix>;
+  };
