[PATCH 0/2] Add PMAU0102 RPMH regulator support

[Shawn Guo]

This series adds RPMH regulator support for PMAU0102 PMIC found on
Qualcomm Nord SoC based devices.

Patch 1 adds the PMAU0102 compatible to the dt-bindings for
qcom,rpmh-regulator, documenting its 8 SMPSes and 3 LDOs.

Patch 2 adds the corresponding vreg data to the rpmh-regulator driver.

Any reason for the NULL supplies?

We thought it's fine to not model LDO supplies, as they may not always
follow PMIC.  But that might be even a good reason for modeling, so that
we can have a better DT description for the supplies.  I will change it
to:

	RPMH_VREG("ldo1",   LDO,  1,  &pmic5_nldo515,    "vdd-l1"),
	RPMH_VREG("ldo2",   LDO,  2,  &pmic5_nldo515,    "vdd-l2"),
	RPMH_VREG("ldo3",   LDO,  3,  &pmic5_pldo515_mv, "vdd-l3"),

Thanks for asking!

Are those the actual supply pins?

From what I can see from schematics, yes, those are supply pins.
