[PATCH 0/9] Add STM32 EXTI interrupt controller support

[Maxime Coquelin]

This series adds support to EXTI interrupt controller and GPIO IRQ support in
STM32 pinctrl driver.

The STM32 external interrupt controller consists of edge detectors that
generate interrupts requests or wake-up events.

Each line can be independently configured as interrupt or wake-up source,
and triggers either on rising, fallin or both edges. Each line can also
be masked independently.

This series applies on top of STM32 pinctrl v2 series.

Regards,
Maxime
