[PATCH v4 6/9] pinctrl: Add IRQ support to STM32 gpios

2016-09-06 Thread Alexandre TORGUE
This patch adds IRQ support to STM32 gpios. The EXTI controller has 16 lines dedicated to GPIOs. EXTI line n can be connected to only line n of one of the GPIO ports, for example EXTI0 can be connected to either PA0, or PB0, or PC0... This port selection is done by specifying the port number into
