Subject: [PATCH v2 3/3] ARM: dts: stm32: Set gpio controller also as interrupt controller
This patch 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.
Acked-by: Linus Walleij <linus.walleij@...aro.org>
