   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.

  74          This implements the generic cpu cooling mechanism through frequency
  75          reduction, cpu hotplug and any other ways of reducing temperature. An
  76          ACPI version of this already exists(drivers/acpi/processor_thermal.c).
  77          This will be useful for platforms using the generic thermal interface
  78          and not the ACPI interface.
  79          If you want this support, you should say Y here.

  85          directory to support temperature emulation. With emulation sysfs node,
