+TAS5756M audio CODEC
+
+Required properties:
+
+  - compatible: should be one of the following:
+    - "ti,tas5756m"
+    - "ti,tas5754m"
+  - reg: the I2C address of the device for I2C.
+
+Optional properties:
+
+  - mute-gpio : GPIO wired to the mute pin.
+  - hybridflow : an integer between 1 and 9 to select the HybridFlow program.
+      if not supplied default DSP program is used.
+
+Example:
+
+	tas5756m: tas5756m@4c {
+		compatible = "ti,tas5756m";
+		reg = <0x4c>;
+		#sound-dai-cells = <0>;
+
+		hybridflow = <6>;
+		mute-gpio = <&gpio1 11 GPIO_ACTIVE_LOW>;
+	};
