+Required properties:
+ - compatible: Must be one of the following:
+               "lltc,ltc1660"
+               "lltc,ltc1665"
+ - reg: SPI chip select number for the device
+ - vref-supply: Phandle to the voltage reference supply
+
+Recommended properties:
+ - spi-max-frequency: Definition as per
+        Documentation/devicetree/bindings/spi/spi-bus.txt.
+        Max frequency for this chip is 5 MHz.
+
+Example:
+dac@0 {
+       compatible = "lltc,ltc1660";
+       reg = <0>;
+       spi-max-frequency = <5000000>;
+       vref-supply = <&vref_reg>;
+};
