• added regulator supply properties.

+This device supports I2C control interface and an IRQ output signal. It features +a PCM and PDM digital audio interface (DAI) and a differential analog input.

Where's the IRQ in the binding?

+Required properties:

• • compatible : "maxim,max98504"
• • reg : should contain the I2C slave device address
• • DVDD-supply, DIOVDD-supply, PVDD-supply: power supplies for the device,
• as covered in Documentation/devicetree/bindings/regulator/regulator.txt

+Example:

• max98504: max98504@31 {
• compatible = "maxim,max98504";
• reg = <0x31>;
• DVDD-supply = <&regulator>;
• DIOVDD-supply = <&regulator>;
• PVDD-supply = <&regulator>;
