If you're nested this deeply, you should consider using labels, e.g.

/ {
       ...

       smd {
               rpm {
                      rpm-requests {
                               regulators: pm8916-regulators {

				};
			};
		};
	};

	...
};


&regulators {
        vdd_l1_l2_l3-supply = <&pm8916_s3>;
        vdd_l5-supply = <&pm8916_s3>;
        vdd_l4_l5_l6-supply = <&pm8916_s4>;
        vdd_l7-supply = <&pm8916_s4>;

	s1 {
                 regulator-min-microvolt = <375000>;
                 regulator-max-microvolt = <1562000>;
	};

        s3 {
	        regulator-min-microvolt = <375000>;
	        regulator-max-microvolt = <1562000>;
        };

	...
};

btw, it seems odd to me that all those nodes under 'smd'
have names but no addresses.
