Subject: [PATCH 14/14] [DO NOT MERGE] ARM: dts: sun8i-r40: bananapi-m2-ultra: Enable OV5640 camera
Date: Mon, 16 Dec 2019 00:59:24 +0800
Message-ID: <20191215165924.28314-15-wens@kernel.org> (raw)
In-Reply-To: <20191215165924.28314-1-wens@kernel.org>

From: Chen-Yu Tsai <wens@csie.org>

Bananapi offers a small OV5640 based camera module, attached via an FPC
connector.

Add the related regulator constraints, and hook everything up.
