Maxim Semiconductor Max77620 supports alarm interrupts when its die temperature crosses 120C and 140C. These threshold temperatures are not configurable. Add thermal driver to register PMIC die temperature as thermal zone sensor and capture the die temperature warning interrupts to notifying the client.

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.
