8 Generic Thermal Sysfs driver offers a generic mechanism for
9 thermal management. Usually it's made up of one or more thermal
10 zone and cooling device.
543a9561 11 Each thermal zone contains its own temperature, trip points,

ZR
12 cooling devices.
13 All platforms with ACPI thermal support can use this driver.
63c4ec90 14 If you want this support, you should say Y or M here.
