Subject: [PATCH] arm: dts: imx6qdl: add gpio expander pca9535
Date: Fri, 12 Jul 2019 14:45:22 +0200	[thread overview]
Message-ID: <20190712124522.571-1-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.
