Public bug reported:
Description:
To better support fan control in DPTF, we need the ACPI fan driver to
expose additional information from BIOS/coreboot. Many designs now
populate the _FPS object with read-only fan performance states. The
entire contents of this object need to be exposed to user-space for
thermal management software such as DPTF to better control the fan.
