[PATCH v2 01/36] dt-bindings: display: allow port and ports in panel-lvds

[Sam Ravnborg]

Both port and ports names may be used.
port - for a single port
ports - if there is more than one port in sub-nodes

Fixes the following warning:
advantech,idk-2121wr.example.dt.yaml: panel-lvds: 'port' is a required property

advantech,idk-2121wr.yaml needs several ports, so uses a ports node.
