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.

388 This enables a thermal sysfs driver for Qualcomm plug-and-play (QPNP)
389 PMIC devices. It shows up in sysfs as a thermal sensor with multiple
390 trip points. The temperature reported by the thermal sensor reflects the
391 real time die temperature if an ADC is present or an estimate of the
392 temperature based upon the over temperature stage value.
