   7         help
   8           Generic Thermal Sysfs driver offers a generic mechanism for
   9           thermal management. Usually it's made up of one or more thermal
  10           zone and cooling device.
  11           Each thermal zone contains its own temperature, trip points,
  12           cooling devices.
  13           All platforms with ACPI thermal support can use this driver.
  14           If you want this support, you should say Y or M here.

  25           framework, this option will also register it
  26           as a hwmon. The sensor will then have the common
  27           hwmon sysfs interface.
