I don't like your indentation, but please stick with one way of doing it :)

This part looks good.
But how about adding all the regulators here as well?
Like:
pm8921_l5: pm8921-l5 {
compatible = "qcom,rpm-pm8921-pldo";
reg = <QCOM_RPM_PM8921_LDO5>;
};
...
That way we can update the references from this file (while still allowing the
dts to override it if needed). I'm not sure if we should add some sane defaults
or just completely deferr specifying the voltage ranges to the dts. The benefit
of the latter is that the regulators not configured by the dts author will not
be accessible.
But simply listing all the nodes here would be nice and I dont see much reason
to postpone this work.
