  13 description: |
  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).
