Subject: [PATCH v2] arm: dts: imx6qdl: add gpio expander pca9535
Date: Fri, 19 Jul 2019 12:46:15 +0200 [thread overview]
Message-ID: <20190719104615.5329-1-gilles.doffe@savoirfairelinux.com> (raw)
The pca9535 gpio expander is present on the Rex baseboard, but missing
from the dtsi.
Add the new gpio controller and the associated interrupt line
MX6QDL_PAD_NANDF_CS3__GPIO6_IO16.
