Subject: [PATCH 5/6] [DO NOT MERGE] ARM: dts: sunxi: bananapi-m2p: Add HDF5640 camera module
Date: Fri, 30 Nov 2018 15:58:48 +0800 [thread overview]
Message-ID: <20181130075849.16941-6-wens@csie.org> (raw)
In-Reply-To: <20181130075849.16941-1-wens@csie.org>
The Bananapi M2+ comes with an optional sensor based on the ov5640 from
Omnivision. Enable the support for it in the DT.
