  1. NTC Thermistor hwmon sensors
  2. -------------------------------
  3. Requires node properties:
  4. - "compatible" value : one of
  5. "epcos,b57330v2103"
  6. "murata,ncp15wb473"
  7. "murata,ncp18wb473"
  8. "murata,ncp21wb473"
  9. "murata,ncp03wb473"
  10. "murata,ncp15wl333"
  11. /* Usage of vendor name "ntc" is deprecated */
  12. <DEPRECATED> "ntc,ncp15wb473"
  13. <DEPRECATED> "ntc,ncp18wb473"
  14. <DEPRECATED> "ntc,ncp21wb473"
  15. <DEPRECATED> "ntc,ncp03wb473"
  16. <DEPRECATED> "ntc,ncp15wl333"
  17. - "pullup-uv" Pull up voltage in micro volts
  18. - "pullup-ohm" Pull up resistor value in ohms
  19. - "pulldown-ohm" Pull down resistor value in ohms
  20. - "connected-positive" Always ON, If not specified.
  21. Status change is possible.
  22. - "io-channels" Channel node of ADC to be used for
  23. conversion.
  24. Optional node properties:
  25. - "#thermal-sensor-cells" Used to expose itself to thermal fw.
  26. Read more about iio bindings at
  27. Documentation/devicetree/bindings/iio/iio-bindings.txt
  28. Example:
  29. ncp15wb473@0 {
  30. compatible = "murata,ncp15wb473";
  31. pullup-uv = <1800000>;
  32. pullup-ohm = <47000>;
  33. pulldown-ohm = <0>;
  34. io-channels = <&adc 3>;
  35. };
