Subject: [PATCH v6 7/7] [DO NOT MERGE] ARM: dts: sun7i: Enable LVDS Dual-Link on the Cubieboard
Date: Fri, 17 Dec 2021 14:51:19 +0100	[thread overview]
Message-ID: <20211217135119.316781-8-maxime@cerno.tech> (raw)
In-Reply-To: <20211217135119.316781-1-maxime@cerno.tech>

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