+Texas Instruments - tas2552 Codec module
+
+The tas2552 serial control bus communicates through I2C protocols
+
+Required properties:
+ - compatible - One of:
+ "ti,tas2552" - TAS2552
+ - reg - I2C slave address
+ - supply-*: Required supply regulators are:
+ "vbat" battery voltage
+ "iovdd" I/O Voltage
+ "avdd" Analog DAC Voltage
+
+Optional properties:
+ - enable-gpio - gpio pin to enable/disable the device
+
+Example:
+
+tas2552: tas2552@41 {
+ compatible = "ti,tas2552";
+ reg = <0x41>;
+ enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>;
+};
