		* "ti,dac6311"
		* "ti,dac5311"
		- reg: spi chip select number for the device
		- vref-supply: The regulator supply for ADC reference voltage

		Optional properties:
		- spi-max-frequency: Max SPI frequency to use

		Example:

		spi_master {
		dac@0 {
		compatible = "ti,dac7311";
		reg = <0>; /* CS0 */
		spi-max-frequency = <1000000>;
		vref-supply = <&vdd_supply>;
		};
		};
