Fairly simple conversion with the exception of the XOR between
spi-cpha and spi-cpol.

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>;
};
