Subject: [PATCH] ARM: dts: exynos: add max77693 irq configuration for midas
Date:   Sun,  8 Jul 2018 00:45:22 +1000
Message-Id: <20180707144527.6662-1-simon@lineageos.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
