Subject: [PATCH v2] ARM: dts: imx50-kobo-aura: Enable eKTF2132 touchscreen
Date: Fri, 13 Nov 2020 00:30:54 +0100 [thread overview]
Message-ID: <20201112233054.3837465-1-j.neuschaefer@gmx.net> (raw)
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.

v2:
- Fix devicetree build by adding #include <dt-bindings/interrupt-controller/irq.h>
- Drop the first two patches, which been applied in the meantime
v1:
