OF graph endpoint connections must be bidirectional and dtc will now warn if they are not. i.MX7 based DTs have an error and generate warnings: Warning (graph_endpoint): /replicator/ports/port@0/endpoint: graph connection to node '/soc/tpiu@30087000/port/endpoint' is not bidirectional Warning (graph_endpoint): /soc/tpiu@30087000/port/endpoint: graph connection to node '/replicator/ports/port@1/endpoint' is not bidirectional This appears to be a copy-n-paste error and the TPIU input should be connected to replicator port 0 instead of port 1.
