Hi,
According to Thomas Gleixner remarks, I add modification on usage of
gpiochip_lock_as_irq
/unlock. For that I adds light modifications in stm32 pinctrl driver and
stm32 exti driver allocation/free irq domain callbacks.
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 v3:
-----------------
- Review domain dealloc/free irq in stm32 pinctrl driver
- Review domain dealloc/free irq in stm32 exti driver
- Fix remarks on coding style
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.)
