   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.

  31           Thermal subsystem will issue a graceful shutdown when
  32           critical temperatures are reached using orderly_poweroff(). In
  33           case of failure of an orderly_poweroff(), the thermal emergency
  34           poweroff kicks in after a delay has elapsed and shuts down the system.
  35           This config is number of milliseconds to delay before emergency
  36           poweroff kicks in. Similarly to the critical trip point,
  37           the delay should be carefully profiled so as to give adequate
  38           time for orderly_poweroff() to finish on regular execution.

 448           Enable the Tango thermal driver, which supports the primitive
 449           temperature sensor embedded in Tango chips since the SMP8758.
 450           This sensor only generates a 1-bit signal to indicate whether
 451           the die temperature exceeds a programmable threshold.

 460           which is connected to the General Purpose ADC. The ADC channel
 461           is read via IIO framework and the channel information is provided
 462           to this driver. This driver reports the temperature by reading ADC
 463           channel and converts it to temperature based on lookup table.
