0015 Newer laptops and tablets that use ACPI may have thermal sensors and
0016 other devices with thermal control capabilities outside the core
0017 CPU/SOC, for thermal safety reasons.
0018 They are exposed for the OS to use via the INT3400 ACPI device object
0019 as the master, and INT3401~INT340B ACPI device objects as the slaves.
0020 Enable this to expose the temperature information and cooling ability
0021 from these objects to userspace via the normal thermal framework.
0022 This means that a wide range of applications and GUI widgets can show
0023 the information to the user or use this information for making
0024 decisions. For example, the Intel Thermal Daemon can use this
0025 information to allow the user to select his laptop to run without
0026 turning on the fans.

0038 The display thermal device represents the LED/LCD display panel
0039 that may or may not include touch support. The main function of
0040 the display thermal device is to allow control of the display
0041 brightness in order to address a thermal condition or to reduce
