        ret = phylink_validate_phy(pl, phy, supported, &config);
        if (ret) {
                phylink_warn(pl, "validation of %s with support %*pb and advertisement %*pb failed: %pe\n",
                             phy_modes(config.interface),
                             __ETHTOOL_LINK_MODE_MASK_NBITS, phy->supported,
                             __ETHTOOL_LINK_MODE_MASK_NBITS, config.advertising,
                             ERR_PTR(ret));

So between "of" and "with" there should be an interface mode. Looking
at
https://elixir.bootlin.com/linux/latest/source/include/linux/phy.h#L223
this suggests configure.interface is PHY_INTERFACE_MODE_NA, which is
0. This could be correct, but it is a bit unlikely.

Also, advertisement 00,00000000,00000000,00000000 looks wrong. It does
not what to advertise anything. The 6 in support means it can do pause
and asymmetric pause, but there are no speeds listed.

So something is wrong with the connection between the MAC and
PHY. Please could you give a link to the .dts file.
