Add a thermal driver to poll and detect any thermal condition at boot and limit max cpu frequency on a thermal condition. This driver is intended to limit cpu thermal output until the userspace thermald kicks in. The thermald will disable this driver and take over the cpu thermal sensing and mitigation.

|
|
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.

|
The generic thermal sysfs driver's hardware monitoring support
|
|
requires a 2.10.7/3.0.2 or later lm-sensors userspace.
|
|
|
|
Say Y if your user-space is new enough.

|

This enables a thermal sysfs driver for MSM POP memory. It shows up in
|
|
sysfs as a thermal zone with one trip point. Due to hardware
|
|
limitations, the temperatures are reported as "Low Temperature" (20 C)
|
|
"Normal Temperature" (50 C) and "Out of Spec High Temperature" (85 C).
|
|
This driver is designed to be used in conjunction with a user space
|
|
application to make all policy decisions.

This enables the thermal sysfs driver for the Tsens device. It shows

up in Sysfs as a thermal zone with mutiple trip points. Disabling the

thermal zone device via the mode file results in disabling the sensor.

Also able to set threshold temperature for both hot and cold and update

This enables a thermal Sysfs driver for the PMIC PM8xxx devices. It

This enables thermal monitoring capability in the kernel in the

absence of a system wide thermal monitoring entity or until such an
