Required properties:



- compatible : "ti,tas5720"

- reg : I2C slave address

- dvdd-supply : phandle to a 3.3-V supply for the digital circuitry

- pvdd-supply : phandle to a supply used for the Class-D amp and the analog



Example:



tas5720: tas5720@6c {

	status = "okay";

	compatible = "ti,tas5720";

	reg = <0x6c>;

	dvdd-supply = <&vdd_3v3_reg>;

	pvdd-supply = <&amp_supply_reg>;

};
