The former has an additional OLDI TX on its first video port (VP0) that helps output cloned video or WUXGA (1920x1200@60fps) resolution video output over a dual-link mode to reduce the required OLDI clock output. Add the new controller's compatible and a port property for the 2nd OLDI TX (OLDI TX 1).
