Ah, this is to keep people from adding "additionalProperties" under the ports node. I will hold off on sending v5 for now. If there happens to be nothing else wrong I'm happy for this to be added by a maintainer when landing or I can quickly spin a v5. > > + > > + properties: > > + "#address-cells": > > + const: 1 > > + > > + "#size-cells": > > + const: 0 > > + > > + port@0: > > + type: object > > + additionalProperties: false > > + > > + description: > > + Video port for MIPI DSI input > > + > > + properties: > > + reg: > > + const: 0 > > + > > + endpoint: > > + type: object > > + additionalProperties: false > > + > > + properties: > > + remote-endpoint: true > > + > > + data-lanes: > > + minItems: 1 > > + maxItems: 4 > > + items: > > + enum: > > + - 0 > > + - 1 > > + - 2 > > + - 3 > > + description: See ../../media/video-interface.txt > > And maybe > uniqueItems: true > > ? Same for port@1. Sounds good. Again, I'll hold off on sending v5 for now and (if no other problems) happy if this gets done when applied. > Reviewed-by: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> Thanks! -Doug _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
