TI DAC7311 device tree bindings

Required properties:

- compatible: must be set to:

	* "ti,dac7311"

	* "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>;

		};

	};
