Subject: [PATCH v1] ARM: dts: imx51-zii-rdu1: fix touchscreen pinctrl
Date: Tue, 19 Jun 2018 23:07:19 +0100 [thread overview]
Message-ID: <20180619220719.3200-1-nick@shmanahar.org> (raw)
The pinctrl settings were incorrect for the touchscreen interrupt line, causing
an interrupt storm. This change has been tested with both the atmel_mxt_ts and
RMI4 drivers on the RDU1 units.
