+NTC Thermistor hwmon sensors
+-------------------------------
+
+Requires node properties:
+- "compatible" value : one of
+ "ntc,ncp15wb473"
+ "ntc,ncp18wb473"
+ "ntc,ncp21wb473"
+ "ntc,ncp03wb473"
+ "ntc,ncp15wl333"
+- "pullup-uv" Pull up voltage in micro volts
+- "pullup-ohm" Pull up resistor value in ohms
+- "pulldown-ohm" Pull down resistor value in ohms
+- "connected-positive" Always ON, If not specified.
+ Status change is possible.
+- "io-channels" Channel node of ADC to be used for
+ conversion.
+
+Read more about iio bindings at
+ Documentation/devicetree/bindings/iio/iio-bindings.txt
+
+Example:
+ ncp15wb473@0 {
+ compatible = "ntc,ncp15wb473";
+ pullup-uv = <1800000>;
+ pullup-ohm = <47000>;
+ pulldown-ohm = <0>;
+ io-channels = <&adc 3>;
+ };
