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 PS8640 is a low power MIPI-to-eDP video format converter supporting
|
|
mobile devices with embedded panel resolutions up to 2048 x 1536. The
|
|
device accepts a single channel of MIPI DSI v1.1, with up to four lanes
|
|
plus clock, at a transmission rate up to 1.5Gbit/sec per lane. The
|
|
device outputs eDP v1.4, one or two lanes, at a link rate of up to
|
|
3.24Gbit/sec per lane.
