I'm not a fan of phy, that makes me expect actual ethernet/sata/usb phy drivers,
which these or not.

Why not just use tcpm ? As Guenter said that is the common denominator.

Anyways this change is fine with me regardless of the name.

OK, tcpm it is. I'll prepare v2.

Thinking about it, that makes sense.

Maybe just use 'port'. Seems to me that 'phy' would not really be a good
match for the port manager (tcpm). 'phy' would still be better than tcpci,
though, so I am ok with it if others think it should be used.

Makes sense.

"port" maybe, but not controller. tps6598x.c is also a controller
driver, but it does not belong to that directory.

How about "phy"?

Does anybody have a proposal/vote what we should use?

NP. I am not sure about the directory name, though. fusb and wcove don't
really support tcpci; only rt1711h does. The common denominator is really
the port manager (tcpm), not the port controller interface (tcpci).

As such, "typec port controller drivers" (without "interface") may be
a bit more appropriate. Not sure about the directory name, though.
Maybe a simple "port" or "controller" would do ? Or anything else that
doesn't look like the abbreviation for one of the supported protocols.

usb: typec: Group all TCPCI/TCPM code together

[Heikki Krogerus]

Moving all the drivers that depend on the Port Controller
Manager under a new a new directory drivers/usb/typec/tcpci/
and making Guenter Roeck as the designated reviewer of that
code.

Hi guys,

This should be fairly trivial change. There is no functional effect.
Even menuconfig looks the same. The only interesting thing is that I'm
proposing that Guenter is marked as the reviewer/maintainer of all
TCPCI/TCPM drivers.

So Guenter, I guess the only question is that are you okay with this?


thanks,
