Subject: [PATCH 1/2] dt-bindings: display: sun4i-tcon: Add LVDS Dual Link property
Date: Fri, 14 Feb 2020 13:32:43 +0100 [thread overview]
Message-ID: <20200214123244.109300-1-maxime@cerno.tech> (raw)
SoCs that have multiple TCONs can use the two set of pins on the first TCON
to drive a dual-link display. Add a property to enable the dual link.
