For any synce pin manipulation over dpll netlink, we can use the netns

The OCP card is an atomic clock, it does not have any networking.

I can't imagine practically havind the whole dpll instance netns aware.
Omitting the fact that it really has no meaning for non-synce pins, what
would be the behaviour when for example pin 1 is in netns a, pin 2 in
netns b and dpll itself in netns c?

To be clear I don't think it's a bad idea in general, I've done 
the same thing for my WIP PSP patches. But we already have one
device without netdevs, hence I thought maybe devlink. So maybe
we do the same thing with devlink? I mean - allow multiple devlink
instances to be linked and require caps on any of them?
