Hi,
According to Maxime, I send this V3 patch set. I took into account Maxime and
Linus discussion about pinctrl-stm32 ("gpio_to_irq" issue). So main changes are
related to add an irq_chip in pinctrl-stm32 and to define a hierarchical
domain for it.
The 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.
Regards
Alex
Changes since v2:
-----------------
- Define irq_chip for GPIO banks
- Use hierarchical domain for GPIO banks
- Improve search loop inside stm32_exti handler
- Rebased on top of v4.8-rc1
Changes since v1:
-----------------
- Rebased on top of v4.6-rc1
- Change variable name from virq to irq (Linus W.)
