I don't have a better reference, but
Linux/Documentation/devicetree/bindings/net/phy.txt says:

 22   If the phy's identifier is known then the list may contain an entry
 23   of the form: "ethernet-phy-idAAAA.BBBB" where
 24      AAAA - The value of the 16 bit Phy Identifier 1 register as
 25             4 hex digits. This is the chip vendor OUI bits 3:18
 26      BBBB - The value of the 16 bit Phy Identifier 2 register as
 27             4 hex digits. This is the chip vendor OUI bits 19:24,
 28             followed by 10 bits of a vendor specific ID.

So the lower 10 bits of 0x1410C00 are 0. So we know it is a Marvell
PHY from the OUI, but the vendor specific bits are all 0.

Please take a look at:

and

Maybe i should submit these two independently, so you can extend it
for the 88E6341 family.
