[PATCH v2 0/3] Add fixes to STM32 pintrl

[PATCH v2 0/3] Add fixes to STM32 pintrl

[Alexandre TORGUE]

This series add several fixes to STM32 pinctrl:
 - Set input mode when PIN is used as interrupt
 - Implement .get_direction() gpio_chip callback  
 - In DT: set each gpio controller as a interrupt controller. User who
   wants to use gpio as interrupt will have choice to use either "gpiolib"
   interface or "common" interrupt interface.

Changes since v1:
 -rebase on 4.12-rc1
 -Let gpiochip and irqchip orthogonal in stm32 pinctrl driver
 -Don't use gpiolib internal define

Regards
Alex
