v3->v4:
* Absorbed patch "dt-bindings: display: Add bindings for LVDS
bus-timings"
* Big restructuring after Rob's and Laurent's comments
v2->v3:
* new patch

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

+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).
