   9           Thermal drivers offer a generic mechanism for
  10           thermal management. Usually it's made up of one or more thermal
  11           zones and cooling devices.
  12           Each thermal zone contains its own temperature, trip points,
  13           and cooling devices.
  14           All platforms with ACPI or Open Firmware thermal support can use
  15           this driver.
  16           If you want this support, you should say Y here.

  40           Thermal subsystem will issue a graceful shutdown when
  41           critical temperatures are reached using orderly_poweroff(). In
  42           case of failure of an orderly_poweroff(), the thermal emergency
  43           poweroff kicks in after a delay has elapsed and shuts down the system.
  44           This config is number of milliseconds to delay before emergency
  45           poweroff kicks in. Similarly to the critical trip point,
  46           the delay should be carefully profiled so as to give adequate

 423           This driver can also be built as a module. If so, the module will
 424           be called amlogic_thermal.
