Whether or not you use auxdev or any other method etc, does not matter
in a DT system, the consumer will always have a phandle to the provider
node:

ABC: whatever {
	compatible =3D "whatever";
	#clock-cells =3D <...>;
	#reset-cells =3D <...>;
}

something-else {
	clocks =3D <&ABC ...>;
	resets =3D <&ABC ...>;
}
