Hello Andrew

Back in February I added PHYLIB support to emac.
<https://www.spinics.net/lists/netdev/msg421734.html> ;)

I could add a separate patch that adds a oneliner message like:
    pr_info("EMAC supports PHYLIB. Please convert your device to it.\n");
at the right place (emac_mii_phy_probe) to let people know about it.

Is that Ok? If not, please tell me what the appropriate deprecation 
notice should look like.

About the MR24:
I do have a patchset to convert the MR24 to use PHYLIB's at803x as well.
<https://github.com/chunkeey/apm82181-lede/commit/82c50b7f4fca68ce905d4a7a3559700635bf227f>
But because of AT8035 "special tx/rx delay" requirements, this
will need a patched at803x.c driver as well.
