+Required properties:
+ - compatible        : Must be "ti,adc084s021"
+ - reg               : SPI chip select number for the device
+ - vref-supply       : The regulator supply for ADC reference voltage
+ - spi-cpol          : Per spi-bus bindings
+ - spi-cpha          : Per spi-bus bindings
+ - spi-max-frequency : Per spi-bus bindings
+
+Example:
+adc@0 {
+       compatible = "ti,adc084s021";
+       reg = <0>;
+       vref-supply = <&adc_vref>;
+       spi-cpol;
+       spi-cpha;
+       spi-max-frequency = <16000000>;
