Looks to me like FWNODE_GRAPH_ENDPOINT_NEXT is always used with endpoint #0. That's equivalent to passing -1 for the endpoint number with the OF API. > Most users dealing with endpoints on fwnode property API use this, could > something like this be done on OF as well? Probably a similar flag would be > needed though. I had fixed almost all the OF cases at one point. Unfortunately, there were a few corner cases that I didn't address to eliminate the API. So now it has proliferated with the fwnode API. Rob
