+Texas Instruments - tlv320aic32x4 Codec module
+
+The tlv320aic32x4 serial control bus communicates through I2C protocols
+
+Required properties:
+ - compatible: Should be "ti,tlv320aic32x4"
+ - reg: I2C slave address
+ - supply-*: Required supply regulators are:
+    "iov" - digital IO power supply
+    "ldoin" - LDO power supply
+    "dv" - Digital core power supply
+    "av" - Analog core power supply
+    If you supply ldoin, dv and av are optional. Otherwise they are required
+   See regulator/regulator.txt for more information about the detailed binding
+   format.
+
+Optional properties:
+ - reset-gpios: Reset-GPIO phandle with args as described in gpio/gpio.txt
+ - clocks/clock-names: Clock named 'mclk' for the master clock of the codec.
+   See clock/clock-bindings.txt for information about the detailed format.
+
+
+Example:
+
+codec: tlv320aic32x4@18 {
+       compatible = "ti,tlv320aic32x4";
+       reg = <0x18>;
+       clocks = <&clks 201>;
+       clock-names = "mclk";
+};
