+* Texas Instruments' ADC128S052 ADC chip
+
+Required properties:
+ - compatible: Should be "ti,adc128s052"
+ - reg: spi chip select number for the device
+ - vref-supply: The regulator supply for ADC reference voltage
+
+Recommended properties:
+ - spi-max-frequency: Definition as per
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Example:
+adc@0 {
+ compatible = "ti,adc128s052";
+ reg = <0>;
+ vref-supply = <&vdd_supply>;
+ spi-max-frequency = <1000000>;
+};
