+TI DAC7311 device tree bindings
+
+Required properties:
+
+- compatible: Must be set to "ti,dac7311", "ti,dac6311" or "ti,dac5311"
+- reg: spi chip select number for the device
+- vref-supply: The regulator supply for ADC reference voltage
+- spi-max-frequency: Max SPI frequency to use (< 50000000)
+
+Example:
+
+ spi_master {
+ dac: dac7311@0 {
+ compatible = "ti,dac7311";
+ reg = <0>; /* CS0 */
+ spi-max-frequency = <1000000>;
+ vref-supply = <&vdd_supply>;
+ };
+ };
