Apologies for the delay. I have set up

https://git.infradead.org/?p=linux-ptp.git
git://git.infradead.org/linux-ptp.git

But I'm not keen on using it without Richard's explicit approval and a
clear understanding of who owns what, *and* the taxonomy we use...

I'm not entirely keen on 'emulated' as the directory name. I don't want
to get too bogged down in bikeshedding, and I know we've done some
already, but I think 'virt' is a better fit? Although when I get my
hands on one of those PTM-capable TimeCards, vmclock won't *just* be
virt... :)

I'm not sure I agree that the drivers being left behind in drivers/ptp
are "IEEE1588 / network-oriented clock drivers" as the commit message
of patch 1 suggests, either. The only one that goes anywhere *near* a
network is ptp_ines.c which has a mii_timestamper interface.

Apart from that they are *all* just PHC clock drivers, aren't they? The
actual network ones live in drivers/net.

So maybe the better answer is to have a more conventional core/drivers
split? Except maybe for ptp_ines is there anything that *network*
maintainers care about, other than the core?

If we do that, add an X: line to exclude the drivers subdir from the
network section in MAINTAINERS, and leave all of drivers/ptp owned by
Richard as it is... do we *need* a new tree?
