Thanks :-)

Documentation/devicetree/bindings/display/bridge/thine,thc63lvd1024.yaml
may be of interest to you, it's a bridge with two LVDS inputs. On the
other side, I've used
Documentation/devicetree/bindings/display/bridge/renesas,lvds.yaml which
is an LVDS encoder with a single output, but with the ability to operate
in dual link mode by coupling two encoder instances.
