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 {
