   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.

  24           In case a sensor is registered with the thermal
  25           framework, this option will also register it
  26           as a hwmon. The sensor will then have the common
  27           hwmon sysfs interface.

  29           Say 'Y' here if you want all thermal sensors to
  30           have hwmon sysfs interface too.

 113           WARNING: Be careful while enabling this option on production systems,

 214           Newer laptops and tablets that use ACPI may have thermal sensors
 215           outside the core CPU/SOC for thermal safety reasons. These
 216           temperature sensors are also exposed for the OS to use via the so
 217           called INT3403 ACPI object. This driver will, on devices that have
 218           such sensors, expose the temperature information from these sensors
 219           to userspace via the normal thermal framework. This means that a wide
 220           range of applications and GUI widgets can show this information to
 221           the user or use this information for making decisions. For example,
