7 title: Advantech IDK-2121WR 21.5" Full-HD dual-LVDS panel

14   The IDK-2121WR from Advantech is a Full-HD dual-LVDS panel.
15   A dual-LVDS interface is a dual-link connection with even pixels traveling
18   The panel expects odd pixels on the first port, and even pixels on the
19   second port, therefore the ports must be marked accordingly (with either
20   dual-lvds-odd-pixels or dual-lvds-even-pixels).
