When using phydev, it should be phy_start/phy_stop'ed properly. This
driver doesn't do that, so add the corresponding calls to port_start/
stop respectively.

This series looks good, applied to net-next, thanks.

Actually, I had to revert.

You cannot use late_initcall_sync() from code that is potentially
built modular, this caused my build to fail at the mdio_bus code.

Hmm, I see. What about you drop patch 5 ("net: phy: suspend unused PHYs
on mdio_bus in late_initcall"), take the rest, and I'll have look at
suspending unused PHYs later?
