13description: |
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
16  on one link, and with odd pixels traveling on the other link.
17
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).
