Zhang Rui203d3d42008-01-17 15:51:08 +08007 help
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.
Len Brown543a9562008-02-07 16:55:08 -050011 Each thermal zone contains its own temperature, trip points,
Zhang Rui203d3d42008-01-17 15:51:08 +080012 cooling devices.
13 All platforms with ACPI thermal support can use this driver.
Zhang Rui63c4ec92008-04-21 16:07:13 +080014 If you want this support, you should say Y or M here.

24 In case a sensor is registered with the thermal
25 framework, this option will also register it
26 as a hwmon. The sensor will then have the common
27 hwmon sysfs interface.

29 Say 'Y' here if you want all thermal sensors to
30 have hwmon sysfs interface too.
