Subject: [PATCH 3/3] ARM: dts: imx50-kobo-aura: Enable eKTF2132 touchscreen
Date: Fri, 6 Nov 2020 12:24:12 +0100 [thread overview]
Message-ID: <20201106112412.390724-4-j.neuschaefer@gmx.net> (raw)
In-Reply-To: <20201106112412.390724-1-j.neuschaefer@gmx.net>
The Kobo Aura has an eKTF2132 touchscreen controller.
Although the vendor kernel toggles a reset pin (GPIO5-12) during the
startup sequence, the touchscreen works without it.
Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net>

This patch requires "[PATCH] ARM: dts: imx50-kobo-aura: Add 'grp' suffix
to pinctrl node names" in order to apply cleanly.
