Thermal is TS-ADC Controller module supports user-defined mode and automatic mode. User-defined mode refers,TSADC all the control signals entirely by software writing to register for direct control. Automaic mode refers to the module automatically poll TSADC output, and the results were checked.If you find that the temperature High in a period of time,an interrupt is generated to the processor down-measures taken;If the temperature over a period of time High, the resulting TSHUT gave CRU module,let it reset the entire chip, or via GPIO give PMIC.

tristate "Generic Thermal sysfs driver"
|
|
help
|
|
Generic Thermal Sysfs driver offers a generic mechanism for
|
|
thermal management. Usually it's made up of one or more thermal
|
|
zone and cooling device.
|
|
Each thermal zone contains its own temperature, trip points,
|
|
cooling devices.
|
|
All platforms with ACPI thermal support can use this driver.
|
|
If you want this support, you should say Y or M here.

In case a sensor is registered with the thermal
