The former has an additional OLDI TX on its first video port that helps output cloned video or WUXGA (1920x1200@60fps) resolution video output over a dual-link mode to reduce the required OLDI clock output. The second video port is same from AM65x DSS and it outputs DPI video data. It can support 2K resolutions @ 60fps, independently. Add the new controller's compatible and update descriptions.
