Subject: ARM: dts: stm32: Set gpio controller as interrupt controller on F4 and F7
X-Git-Tag: v4.13-rc1~168^2~19^2~11
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=5489d5dbb497ca3c6301f33792bcca1c064de98e;p=linux.git

ARM: dts: stm32: Set gpio controller as interrupt controller on F4 and F7

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.
