Nope. I tested single LVDS link with the second LVDS link. It didn't work.

Still port@0 is a single LVDS instance or first LVDS input link for the dual LVDS configuration??

"port@0" always represents the first LVDS link and "port@1" always represents the second LVDS link, no matter it's a single-link LVDS or a dual-link LVDS. Which one is the first/second LVDS link? See "LVDS front-end interface pin" in IT6263 data sheet[1] where first/second are defined.
