This property has always been supported by the Linux driver; see commit 9f93ac8d4085 ("net-next: stmmac: Add dwmac-sun8i"). In fact, the original driver submission includes the phy-supply code but no mention of it in the binding, so the omission appears to be accidental. In addition, the property is documented in the binding for the previous hardware generation, allwinner,sun7i-a20-gmac. Document phy-supply in the binding to fix devicetree validation for the 25+ boards that already use this property.
