[PATCH] Add driver to force WMI Thunderbolt controller power status

2017-09-06 Thread Mario Limonciello
Current implementations of Intel Thunderbolt controllers will go into a low power mode when not in use. Many machines containing these controllers also have a GPIO wired up that can force the controller awake. This is offered via a ACPI-WMI interface intended to be manipulated by a userspace util
