Are there any open > issues or Ack you're waiting for? The only worry is the silence from Rob on that multiple-endpoint discussion. Since I don't really care deeply, my plan was fix up the of_node leak in v7 without using of_graph_parse_endpoint. I.e. drop 3/4. But I would have prefer Rob to add some final opinion instead of the discussion petering out like it did. Cheers, Peter
