| 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. |
