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.

This binding supports transparent LVDS encoders and decoders that don't
|
|
require any configuration.
|
|
|
|
LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
|
|
incompatible data link layers have been used over time to transmit image data
|
|
to LVDS panels. This binding targets devices compatible with the following
|
|
specifications only.
