Subject: [RFC V2 5/5] arm64: dts: imx8mm-evk: Enable OV5640 Camera
Date: Sat, 23 Oct 2021 15:34:56 -0500	[thread overview]
Message-ID: <20211023203457.1217821-6-aford173@gmail.com> (raw)
In-Reply-To: <20211023203457.1217821-1-aford173@gmail.com>

The schematic shows support for a camera interface, and the NXP
kernel shows it is an OV5640.
