[PATCH 0/4] Add supply names for PM6350 RPMh regulators on Fairphone 4

[PATCH 0/4] Add supply names for PM6350 RPMh regulators on Fairphone 4

[Luca Weiss]

During bringup no parent supply names were added to the RPMh regulator
driver. Add them now.

[PATCH 3/4] regulator: qcom-rpmh: Add missing regulators in PM6350

[Luca Weiss]

Add the missing smps3-6 and ldo17 definitions. While smps3/5 and ldo17
are not used from the rpmh regulator driver on SM6350, the regulators do
exist, so add them with the types based on the datasheet.

[PATCH 4/4] arm64: dts: qcom: sm7225-fairphone-fp4: Add parent supply for regulators

[Luca Weiss]

Add the vdd-*-supply properties to the rpmh-regulators nodes, so that
the parent regulators can be enabled when needed.

The regulators s4a and s6a are a bit special. They feed back into
PM6350, but are not modelled as regulators (or anything else?), so they
also can't be added as vdd-*-supply. It would seem to be possible to add
them with their "Default on booting voltage" from the PM6350 Data Sheet
in the dts, but I'm not sure this is desired.

And document what the "missing" regulators are used for.

L17 (and other NLDOs on this PMIC) can do 0.312 - 1.304 V, whereas
the pmic5_nldo config allows a range of 0.32 - 1.296 V. But I suppose
that is something to fix separately anyway

Yeah they seem to be strictly intended as being part of the internal
PMIC power grid.
