[PATCH] ARM: dts: exynos: add max77693 irq configuration for midas
From: Simon Shields
Date: Sat Jul 07 2018 - 10:51:25 EST
Currently, we assume that the bootloader has correctly configured
the interrupt pin for max77693. This might not actually be the case -
so it's better to configure it explicitly.
