-Texas Instruments 8/10/12-bit 2/4-channel DAC driver
-
-Required properties:
- - compatible:		Must be one of:
-			"ti,dac082s085"
-			"ti,dac102s085"
-			"ti,dac122s085"
-			"ti,dac084s085"
-			"ti,dac104s085"
-			"ti,dac124s085"
- - reg: 		Chip select number.
- - spi-cpha, spi-cpol:	SPI mode (0,1) or (1,0) must be used, so specify
-			either spi-cpha or spi-cpol (but not both).
- - vref-supply: 	Phandle to the external reference voltage supply.
-
-For other required and optional properties of SPI slave nodes please refer to
-../../spi/spi-bus.txt.
-
-Example:
-	vref_2v5_reg: regulator-vref {
-		compatible = "regulator-fixed";
-		regulator-name = "2v5";
-		regulator-min-microvolt = <2500000>;
-		regulator-max-microvolt = <2500000>;
-		regulator-always-on;
-	};
-
-	dac@0 {
-		compatible = "ti,dac082s085";
-		reg = <0>;
-		spi-max-frequency = <40000000>;
-		spi-cpol;
-		vref-supply = <&vref_2v5_reg>;
-	};
