-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.

- vref_2v5_reg: regulator-vref {

- regulator-max-microvolt = <2500000>;
