Subject: [PATCH v2 4/4] [DO NOT MERGE] ARM: dts: sun7i: Enable LVDS Dual-Link on the Cubieboard
Date: Thu, 30 Jul 2020 11:35:04 +0200	[thread overview]
Message-ID: <da488b254cfed95796561873f9b400c40f290796.1596101672.git-series.maxime@cerno.tech> (raw)
In-Reply-To: <cover.7029eefe5c5350920f91d4cd4cbc061466752f3c.1596101672.git-series.maxime@cerno.tech>

For the sake of the example, let's enable an LVDS Dual-Link display on a
Cubieboard.
