Subject: [PATCH v5 3/7] dt-bindings: display: sun4i: Add LVDS Dual-Link property
Date: Wed, 29 Sep 2021 10:42:30 +0200	[thread overview]
Message-ID: <20210929084234.1271915-4-maxime@cerno.tech> (raw)
In-Reply-To: <20210929084234.1271915-1-maxime@cerno.tech>

The Allwinner SoCs with two TCONs and LVDS output can use both to drive an
LVDS dual-link. Add a new property to express that link between these two
TCONs.

Signed-off-by: Maxime Ripard <maxime@cerno.tech>
