Aug 29, 2015 · We can use 16 external interrupt line (line0 to line15) to detect external event from GPIO pins. Each pin from all GPIO port is connected to each external interrupt line with the same number. PA0, PB0, PC0 and so on, are multiplexed to line0.

Subsystem drivers using GPIO¶. Note that standard kernel drivers exist for common GPIO tasks and will provide the right in-kernel and userspace APIs/ABIs for the job, and that these drivers can quite easily interconnect with other kernel subsystems using hardware descriptions such as device tree or ACPI:
