+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>;
+ };
