+* MAX1117/MAX1118/MAX1119 8-bit, dual-channel ADCs
+
+Required properties:
+ - compatible: Should be one of
+	* "maxim,max1117"
+	* "maxim,max1118"
+	* "maxim,max1119"
+ - reg: spi chip select number for the device
+ - (max1118 only) 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 = "maxim,max1118";
+	reg = <0>;
+	vref-supply = <&vdd_supply>;
+	spi-max-frequency = <1000000>;
