NTC Thermistor hwmon sensors
-------------------------------
Requires node properties:
- "compatible" value : one of
"epcos,b57330v2103"
"murata,ncp15wb473"
"murata,ncp18wb473"
"murata,ncp21wb473"
"murata,ncp03wb473"
"murata,ncp15wl333"
"murata,ncp03wf104"
/* Usage of vendor name "ntc" is deprecated */
<DEPRECATED> "ntc,ncp15wb473"
<DEPRECATED> "ntc,ncp18wb473"
<DEPRECATED> "ntc,ncp21wb473"
<DEPRECATED> "ntc,ncp03wb473"
<DEPRECATED> "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.
Optional node properties:
- "#thermal-sensor-cells" Used to expose itself to thermal fw.

Example:
ncp15wb473@0 {
compatible = "murata,ncp15wb473";
pullup-uv = <1800000>;
pullup-ohm = <47000>;
pulldown-ohm = <0>;
io-channels = <&adc 3>;
};
