Hi Rob, again

quoted

This is assuming there's just 1 port and 1 endpoint, but let's be 
specific as the bindings are (first endpoint on port 0):

of_graph_get_endpoint_by_regs(client->dev.of_node, 0, -1);

Note we could ask for endpoint 0 here, but the bindings generally allow 
for more than 1.

I imagine most of the other cases here are the same.

I'm bit confused here.
You mentioned that -1 is wrong in previous mail.

	Most cases are in the form of of_graph_get_next_endpoint(dev, NULL) 
	which is equivalent to of_graph_get_endpoint_by_regs(dev, 0, 0). 
	Technically, -1 instead of 0 is equivalent, but I'd argue is sloppy and 
	wrong.

But you mentioned -1 here, So, I will use it on next patch-set.


Thank you for your help !!

Best regards
