~/linux/drivers/net/ethernet/stmicro/stmmac$ grep regulator_get *
dwmac-rk.c:	bsp_priv->regulator = devm_regulator_get(dev, "phy");
dwmac-sun8i.c:	gmac->regulator = devm_regulator_get_optional(dev, "phy");
dwmac-sunxi.c:	gmac->regulator = devm_regulator_get_optional(dev, "phy");

Maybe i'm missing something, but i don't see an actual implementation
of this binding?
