   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.

  34          Use the step_wise governor as default. This throttles the

  42          devices based on their 'contribution' to a zone. The
  43          contribution should be provided through platform data.

  73        help
  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.

 109          Adds DB8500 thermal management implementation according to the thermal
 110          management framework. A thermal zone with several trip points will be
 111          created. Cooling devices can be bound to the trip points to cool this

 120          Adds DB8500 cpufreq cooling devices, and these cooling devices can be
 121          bound to thermal zone trip points. When a trip point reached, the
 122          bound cpufreq cooling device turns active to set CPU frequency low to
 123          cool down the CPU.
