Neither the ACPI description on Intel Minnowboard (v1) platform provides the required information to establish a generic handling nor the hardware capable of doing it. According to the data sheet the hardware can generate SCI events. Therefore, we need to hook from the driver into GPE handler of the ACPI subsystem in order to catch and report GPIO-related events.
Validated on the Inlel Minnowboard (v1) platform and Intel Galileo Gen 2.
