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. -- Regards, Laurent Pinchart
