Interesting that it doesn't match the following in Documentation/devicetree/bindings/net/ethernet-phy.yaml

      - pattern: "^ethernet-phy-id[a-f0-9]{4}\\.[a-f0-9]{4}$"
        description:
          If the PHY reports an incorrect ID (or none at all) then the
          compatible list may contain an entry with the correct PHY ID
          in the above form.
          The first group of digits is the 16 bit Phy Identifier 1
          register, this is the chip vendor OUI bits 3:18. The
          second group of digits is the Phy Identifier 2 register,
          this is the chip vendor OUI bits 19:24, followed by 10
          bits of a vendor specific ID.
