Kernel-3.10.0-957.el7_ntc_thermistor

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.

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