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

as a hwmon. The sensor will then have the common

hwmon sysfs interface.

Say 'Y' here if you want all thermal sensors to

have hwmon sysfs interface too.
