The ACPI thermal library contains functions that can be used to retrieve trip point temperature values through the platform firmware for various types of trip points. Each of these functions basically evaluates a specific ACPI object, checks if the value produced by it is reasonable and returns it (or THERMAL_TEMP_INVALID if anything fails). It made sense to hold it in drivers/thermal/ so long as it was only used by the code in that directory, but since it is also going to be used by the ACPI thermal driver located in drivers/acpi/, move it to the latter in order to keep the code related to evaluating ACPI objects defined in the specification proper together. No intentional functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

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 INT3400 ACPI device object
|
|
as the master, and INT3401~INT340B ACPI device objects as the slaves.
|
|
Enable this to expose the temperature information and cooling ability
|
|
from these objects to userspace via the normal thermal framework.
|
|
This means that a wide range of applications and GUI widgets can show
|
|
the 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 without
|
|
turning on the fans.

The display thermal device represents the LED/LCD display panel

that may or may not include touch support. The main function of
|

the display thermal device is to allow control of the display

brightness in order to address a thermal condition or to reduce

power consumed by display device.
