Subject: [PATCH v4 3/7] dt-bindings: display: sun4i: Add LVDS Dual-Link property
Date: Fri, 19 Feb 2021 14:59:30 +0100 [thread overview]
Message-ID: <20210219135934.618684-4-maxime@cerno.tech> (raw)
In-Reply-To: <20210219135934.618684-1-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>
