I didn't mean that. You can get rid of this entire xlate stuff if you use
something like below

phy@xxx {
	compatible = "";
	phy1:usb_phy {
	}
	phy2:usb_phy {
	};
};


usb@xx {
	compatible = "";
	phys = <&phy1>; //doesn't need xlate
	/* this needs xlate
	   phys = <&phy 1>;
	*/
	phy-names = "phy";
};

Thank you so much for your suggestion, but still have a question:
I have to add the #phy-cells property in each phy sub-node, otherwise devm_get_phy() will fail and I get log info like "/usb@ff500000: could not get #phy-cells for /phy/usbp-phy1". So can the #phy-cells property defines in patent node
also valid for it's child nodes like #address-cells ?
