+* Maxim max11100 Analog to Digital Converter (ADC)
+
+Required properties:
+ - compatible: Should be "maxim,max11100"
+ - reg: the adc unit address
+ - vref-supply: phandle to the regulator that provides reference voltage
+
+Optional properties:
+ - spi-max-frequency: SPI maximum frequency
+
+Example:
+
+max11100: adc@0 {
+ compatible = "maxim,max11100";
+ reg = <0>;
+ vref-supply = <&adc0_vref>;
+ spi-max-frequency = <240000>;
+};
