Hi, Currently 4.9-rc1 is not booting correctly on STM32F4. By adding gpios irqs support to stm32 pinctrl, a dependency has been added between pinctrl stm32 and stm32f4 device tree (my mistake). This series breaks this dependency and has to be taken on 4.9_rcs.

stm32 pinctrl driver could be probed even if no interrupt controller
is defined to manage gpio irqs. Entries related to gpio irq management
are moved to optional.
