Hi, I'm trying to fix the dtbs_check warning: /soc@0/bus@32c00000/isi@32e20000/ports: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary OF graphs with a single port should be placed inside a 'port' node, rather than a single 'port' node inside a 'ports' node. Bindings were designed for the latter case. Adjust the bindings so a seconds port (port@1) is not allowed for single-pipeline models and allow both 'ports' (current one) and 'port' based OF graph connections for single-pipeline models.
