The Processor Thermal PCI device supports multiple features. Currently we export only RAPL. But we need more features from this device exposed for Tiger Lake and Alder Lake based platforms. So re-structure the current MMIO interface, so that more features can be added cleanly. No functional changes are expected with this change. Changes done in this patch: - Using PCI_DEVICE_DATA(), hence names of defines changed - Move RAPL MMIO code to its own module - Move the RAPL MMIO offsets to RAPL MMIO module - Adjust Kconfig dependency of PROC_THERMAL_MMIO_RAPL - Per processor driver data now contains the supported features - Moved all the common data structures and defines to a common header file - This new header file contains all the processor_thermal_* interfaces - Based on the features supported the module interface is called - Each module atleast provides one add and one remove function Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20201126171829.945969-1-srinivas.pandruvada@linux.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.
