I didn't notice it, thanks for pointing it out!
Apart from the obvious overlap of adding UCLASS_MDIO and code like
_post_probe they seem to deal with different needs.
Ken, can you please take a look at the patch I sent? It has a
wrapper over phy_connect, but provides no helpers on how the caller
would get the PHY ADDR. Do you want to try pulling the API you add on
top of the patch I sent, or do you want me to try? It looks like it
would work with minimal effort.
