3Required 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.
