Subject: [PATCH 0/4] regulator: Add X-Powers AXP717 PMIC support

This patch series adds support for the X-Powers AXP717 PMIC, which is 
used recently on new boards with Allwinner SoCs.
Allwinner's BSP code often speaks of the AXP2202, this seems to be the
same chip, at least a boot0 AXP2202 driver happily drove a chip labelled
AXP717.

Patch 1 fixes a typo in some macro names for the AXP313a PMIC, I just
realised that during some copy&paste action. It's just an identifier
rename, so not a backport candidate, I'd say.
Patch 2 adds the compatible string to the binding document.
Patch 3 is the MFD part, describing the regmap and all the interrupts.
So far we support the regulator and power key devices, the USB and
charging devices will follow later.
Patch 4 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.

Please note that I could not test this driver myself, but had success
messages from others. It would be good to hear from Ryan and Chris
here on the list, with a Tested-by: tag.

This series is based on next-20240308 for now. I will send a rebased
update after the merge window, but wanted to start discussion and review
now.

Please have a look!

Cheers,
Andre
