  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. "murata,ncp03wf104"
  12. /* Usage of vendor name "ntc" is deprecated */
  13. <DEPRECATED> "ntc,ncp15wb473"
  14. <DEPRECATED> "ntc,ncp18wb473"
  15. <DEPRECATED> "ntc,ncp21wb473"
  16. <DEPRECATED> "ntc,ncp03wb473"
  17. <DEPRECATED> "ntc,ncp15wl333"
  18. - "pullup-uv" Pull up voltage in micro volts
  19. - "pullup-ohm" Pull up resistor value in ohms
  20. - "pulldown-ohm" Pull down resistor value in ohms
  21. - "connected-positive" Always ON, If not specified.
  22. Status change is possible.
  23. - "io-channels" Channel node of ADC to be used for
  24. conversion.
  25. Optional node properties:
  26. - "#thermal-sensor-cells" Used to expose itself to thermal fw.
  27. Read more about iio bindings at
  28. Documentation/devicetree/bindings/iio/iio-bindings.txt
  29. Example:
  30. ncp15wb473@0 {
  31. compatible = "murata,ncp15wb473";
  32. pullup-uv = <1800000>;
  33. pullup-ohm = <47000>;
  34. pulldown-ohm = <0>;
  35. io-channels = <&adc 3>;
  36. };
