[PATCH 00/10] Convert MSM8916 to use rpmpd/power domains

Newer platforms vote for necessary power domains through the power
domain subsystem. For historical reasons older platforms like MSM8916
or MSM8974 still control these as regulators.

This patch series adds the power domain definitions for MSM8916
to the rpmpd driver. Then, qcom_q6v5_mss and qcom_wcnss are updated
to use power domains for MSM8916/MSM8974. For compatibility with old
device trees (and for MSM8974) we still need to support using the
power domains through the regulator interface. This is implemented by
falling back to the regulators if requesting the power domains fails.

Finally, we remove the regulators that provide the power domains
(s1 and l3) entirely from the MSM8916 device tree: They should only
be used through the power domain subsystem from now on.
