Subject: [PATCH 14/15] sama5d3 dts: enable atmel-isi
Date: Mon, 12 Dec 2016 16:55:19 +0100	[thread overview]
Message-ID: <20161212155520.41375-15-hverkuil@xs4all.nl> (raw)
In-Reply-To: <20161212155520.41375-1-hverkuil@xs4all.nl>

From: Hans Verkuil <hans.verkuil@cisco.com>

This illustrates the changes needed to the dts in order to hook up the
ov7670. I don't plan on merging this.
