That is my current suggestion.

It stems from Jakub's response in
https://lore.kernel.org/all/[email protected]/ that "I
really wish someone stepped up and created a separate subsystem for all
these cloud / vm clocks. They have nothing to do with PTP."

There was some further bikeshedding in
https://lore.kernel.org/netdev/[email protected]=
libaba.com/
around how to split 'emulated' from other hardware drivers, but I don't
much like that taxonomy. Some of these "virtual" clocks could just as
easily exist in hardware with PTM too.

My observation is that with the sole exception of ptp_inet.c, *all* of
the actual PHC drivers that live in drivers/ptp instead of drivers/net
are "pure clock" drivers, so perhaps we split those all out into
drivers/ptp/drivers/ and exclude them from the netdev maintenance?

I'm reluctantly prepared to host and help maintain a drivers tree if
it's necessary, but equally as happy to let you own it.=20
