Hi,

Newer laptops and tablets that use ACPI may have thermal sensors and other
devices with thermal control capabilities outside the core CPU/SOC, for
thermal safety reasons.
They are exposed for the OS to use via the ACPI INT340x device objects.

This patch set introduces kernel drivers for those INT340X devices and
expose their telemetry and cooling capability to user space via the normal
thermal framework. So that a wide range of applications and GUI widgets
can show this information to the user or use this information for making
decisions. For example, the Intel Thermal Daemon can use this information
to allow the user to select his laptop to run w/ or w/o turning on the fans.

thanks,
rui
