Subject: [PATCH RESEND v3 2/6] dt-bindings: display: sun4i: Add LVDS Dual-Link property
Date: Mon, 5 Oct 2020 17:15:40 +0200 [thread overview]
Message-ID: <2bc93c7c1d3121730239a01dda9c30dcf4e353b0.1601910923.git-series.maxime@cerno.tech> (raw)
In-Reply-To: <cover.6cdb798a6b393c8faa9c1297bbdfb8db81238141.1601910923.git-series.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>
