[RFC PATCH 0/3] regulator: Add X-Powers AXP318W PMIC support

[Andre Przywara]

This patch series adds support for the X-Powers AXP318W PMIC, which is
used recently on new boards with Allwinner SoCs (the A733).
It features 9 DCDC buck converters and 28 LDOs, plus the usual ADC,
interrupts, and power key components.
I am marking this as RFC, as this is untested, since I don't have hardware,
but at least the datasheet [1] gives enough information to get the review
and discussion started.

Patch 1 adds the compatible string to the binding document, and adds
the additional input supply properties.
Patch 2 is the MFD part, describing the regmap and all the interrupts.
So far we support the regulator and power key devices, the ADC and
other pieces will follow later.
Patch 3 adds the voltage regulator rails, this part is crucial to enable
any board using this PMIC, as we depend on those rails even for basic
devices.
Based on v6.17-rc1.

Please have a look!

Cheers,
Andre
