0013 description: |
0014 The IDK-2121WR from Advantech is a Full-HD dual-LVDS panel.
0015 A dual-LVDS interface is a dual-link connection with even pixels traveling
0016 on one link, and with odd pixels traveling on the other link.
0017
0018 The panel expects odd pixels on the first port, and even pixels on the
0019 second port, therefore the ports must be marked accordingly (with either
0020 dual-lvds-odd-pixels or dual-lvds-even-pixels).
