Now that we have a graph schema, rework the display related schemas to use it. Mostly this is adding a reference to graph.yaml and dropping duplicate parts from schemas. In panel-common.yaml, 'ports' is dropped. Any binding using 'ports' should be one with more than 1 port node, and the binding must define what each port is. Note that ti,sn65dsi86.yaml, ti,tfp410,yaml and toshiba,tc358768.yaml will need further updates to use video-interfaces.yaml once that lands.

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).
