From b9639a8b5ef1fa90fc0152db15588a9fe601c4b0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonathan=20Neusch=C3=A4fer?= Date: Fri, 13 Nov 2020 00:30:54 +0100 Subject: [PATCH] ARM: dts: imx50-kobo-aura: Enable eKTF2132 touchscreen MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
