I missed the original posting of this, so let me reply here:
Nack to this change, I've a patch-set in the works to
make display-port over type-c work with 2 devices with a fusb302
mux and that needs this connection.
I can add the connections back in this series after the API
modification patches, but should the connections be added back only
after we actually support the alt mode in the driver?
Btw. I'm preparing patches where I remove struct tcpc_config
completely. We can do that by taking advantage of the software fwnodes
(I'll send the patches RFC to give you an idea what I'm talking about).
That's related as we don't need struct tcpc_config for anything else
except for alternate modes (which no driver supports currently) after
that series, and even with the alt modes, it's only a question of
supplying DT bindings that define the appropriate device properties.
Also, as a "heads-up": As I explained in the cover-letter, my plan is
to take advantage of the software fwnodes also with the connections.
By adding support for reference handling to the software nodes, we
don't need to maintain the list of connections as we do today. And
more importantly, we don't need to match using device names, which is
always fragile.
That means we will change the connection registration, actually,
remove connection registration :-). The connections after that can
always be described in the fwnode for the device.
I see that you've posted a v2 series now and that you've kept the dev_name
matching for platforms where there are no fwnodes to match on, thanks.
I've just reviewed the v2 series and it looks good to me, I will reply
there.

Hans
