+* Nuvoton NAU7802 Analog to Digital Converter (ADC)
+
+Required properties:
+  - compatible: Should be "nuvoton,nau7802"
+  - reg: Should contain the ADC I2C address
+
+Optional properties:
+  - nuvoton,vldo: Internal reference voltage in millivolts to be
+    configured valid values are between 2400 mV and 4500 mV.
+  - interrupts: IRQ line for the ADC. If not used the driver will use
+    polling.
+
+Example:
+adc2: nau7802@2a {
+       compatible = "nuvoton,nau7802";
+       reg = <0x2a>;
+       nuvoton,vldo = <3000>;
+};
