Overall I like it, some nitpicks and notes inline.
Eventually we'll probably want to convert the "tc_port" in register
macros to "phy" or something, but no rush.
With the issues fixed,

Btw why the "is" -> "has" in the function name?

Ditto.
Also leave the "else if" intact?

I think it would just be more maintainable to keep using enum phy as the
type for phy.
