3 Required properties:
4 - compatible: Must be one of:
5 "ti,dac082s085"
6 "ti,dac102s085"
7 "ti,dac122s085"
8 "ti,dac084s085"
9 "ti,dac104s085"
10 "ti,dac124s085"
11 - reg: Chip select number.
12 - spi-cpha, spi-cpol: SPI mode (0,1) or (1,0) must be used, so specify
13 either spi-cpha or spi-cpol (but not both).
14 - vref-supply: Phandle to the external reference voltage supply.

20 vref_2v5_reg: regulator-vref {
21 compatible = "regulator-fixed";
22 regulator-name = "2v5";
23 regulator-min-microvolt = <2500000>;
24 regulator-max-microvolt = <2500000>;
25 regulator-always-on;
26 };

28 dac@0 {
29 compatible = "ti,dac082s085";
30 reg = <0>;
31 spi-max-frequency = <40000000>;
32 spi-cpol;
33 vref-supply = <&vref_2v5_reg>;
34 };
