Since we can compress clock-names, we should just do that :-)

Well, the MDIO bus is part of the IP anyway, so I think we can just put it here.
eth_mdio: mdio {
compatible = "snps,dwmac-mdio";
#address-cells = <1>;
#size-cells = <0>;
};

Please reorder:

snps,rd_osr_lmt = <0x7>;
snps,wr_osr_lmt = <0x7>;
