Subject: [PATCH 3/5] ARM: dts: exynos: add pinctrl for midas fuelgauge irq pin
Date:   Sat, 21 Jul 2018 22:50:51 +1000
Message-Id: <20180721125128.31498-4-simon@lineageos.org>
In-Reply-To: <20180721125128.31498-1-simon@lineageos.org>
References: <20180721125128.31498-1-simon@lineageos.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This pin is externally pulled up, so we should disable the SoC's
pull down resistor in order for the interrupt to function properly.
