+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: it can be 0x40 if ADDR pin is 0
+				    or 0x41 if ADDR pin is 1.
+	- 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
+
+tas2552 can receive its reference clock via MCLK, BCLK, IVCLKIN pin or use the
+internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM
+reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK.
+For system integration the dt-bindings/sound/tas2552.h header file provides
+defined values to select and configure the PLL and PDM reference clocks.
+
+Example:
+
+tas2552: tas2552@41 {
+	compatible = "ti,tas2552";
+	reg = <0x41>;
+	vbat-supply = <&reg_vbat>;
+	iovdd-supply = <&reg_iovdd>;
+	avdd-supply = <&reg_avdd>;
+	enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>;
+};
