The SC2 platform inherited a lot from G12A, therefore it's plausible
that it's the same PHY. Also the vendor driver for SC2 gives a hint
as it has the following compatible for the PHY:

compatible = "ethernet-phy-id0180.3301", "ethernet-phy-ieee802.3-c22";

But you're right, I can't say for sure as I don't have the datasheets.
