Hi Jacky,

I understand the aim of this patch, and I think it is nice that we
can drop about 20 lines of code. But I did have some trouble understanding
the paragraph above. I wonder if the following is clearer:

  Consolidate the handling of dedicated PHY and fixed-link phy by taking
  advantage of logic in of_phy_get_and_connect() which handles both of
  these cases, rather than open coding the same logic in ftgmac100_probe().

I agree that this is not a fix. And should not have a Fixes tag and so on.
But as such it should be targeted at net rather than net-next.

The code themselves changes look good to me. But I think the two points
above, in combination, warrant a v3.
