Then we might not be talking about the same thing. I'm talking about DT
bindings to represent the topology of the device, not how drivers are
wired together.

Possibly. I'm certainly confused now. You brought up the component helpers
in drivers/base/component.c, so I thought working out dependencies is part
of the purpose of this binding. Everything I've heard so far has given me
the impression that the graph binding is tied up with knowing when all of
the devices exist.

The two are related, you're of course right about that.

We're not really moving forward here. Part of our disagreement comes in my 
opinion from having different requirements and different views of the problem, 
caused by experiences with different kind of devices. This is much easier to 
solve by sitting around the same table than discussing on mailing lists. I 
would propose a meeting at the ELC but that's still a bit far away and would 
delay progress by more than one month, which is probably not acceptable.

I can reply to the e-mail where I've drawn one use case I have to deal with to 
detail my needs if that can help.

Alternatively the UK isn't that far away and I could jump in a train if you 
can provide tea for the discussion :-)

I'm game for that, but it is a long train ride. I'm up in Aberdeen which
is 8 hours from London by train. Also, I'm travelling next week to
California (Collaboration summit), so it will have to be in 2 weeks
time.

Why don't we instead try a Google Hangout or a phone call today.
Anywhere between 11:30 and 14:00 GMT would work for me. I'd offer to
provide the tea, but I haven't quite perfected transporter technology
yet.
