Subject: [PATCH v2 2/4] arm64: dts: imx8mq-librem5: add pinctrl for the touchscreen description
Date: Tue, 22 Dec 2020 16:13:45 +0100 [thread overview]
Message-ID: <20201222151347.7886-3-martin.kepplinger@puri.sm> (raw)
In-Reply-To: <20201222151347.7886-1-martin.kepplinger@puri.sm>
In order for the touchscreen interrupt line to work, describe it properly.
Otherwise it can work if defaults are ok, but we cannot be sure.
Fixes: 8f0216b006e5 ("arm64: dts: Add a device tree for the Librem 5 phone")
Signed-off-by: Martin Kepplinger <martin.kepplinger@puri.sm>
