+description: |
+ The IDK-2121WR from Advantech is a Full-HD dual-LVDS panel.
+ A dual-LVDS interface is a dual-link connection with even pixels traveling
+ on one link, and with odd pixels traveling on the other link.
+
+ The panel expects odd pixels on the first port, and even pixels on the
+ second port, therefore the ports must be marked accordingly (with either
+ dual-lvds-odd-pixels or dual-lvds-even-pixels).
