+* Texas Instruments' ADS8684 and ADS8688 ADC chip
+
+Required properties:
+ - compatible: Should be "ti,ads8684" or "ti,ads8688"
+ - reg: spi chip select number for the device
+
+Recommended properties:
+ - spi-max-frequency: Definition as per
+		Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Optional properties:
+ - vref-supply: The regulator supply for ADC reference voltage
+
+Example:
+adc@0 {
+	compatible = "ti,ads8688";
+	reg = <0>;
+	vref-supply = <&vdd_supply>;
+	spi-max-frequency = <1000000>;
+};
