Hello,

the following implements basic support for Marvell's 88PM886 PMIC which
is found for instance as a component of the samsung,coreprimevelte
smartphone which inspired this and also serves as a testing platform.

The code for the MFD is based primarily on this old series [1] with the
addition of poweroff based on the smartphone's downstream kernel tree
[2]. The onkey and regulators drivers are based on the latter. I am not
in possesion of the datasheet.

Thank you and kind regards,
K. B.

v6:
- Rebase to v6.9-rc6.
- Fix patchset versioning: the previous version was marked as v1 because I
  considered RFC to be its own thing. Thank you to Krzysztof for
  explaining that that is not the case. The previous version is thus now
  marked as v5 and this is v6, sorry for any confusion.
- v5: https://lore.kernel.org/r/20240331105608.7338-2-balejk@matfyz.cz/
v5:
- RFC v4: https://lore.kernel.org/r/20240311160110.32185-1-karelb@gimli.ms.mff.cuni.cz/

- Address Rob's feedback:
  - Drop onkey bindings patch.
- Rename PM88X -> PM886 everywhere.
- RFC v2: https://lore.kernel.org/all/20240211094609.2223-1-karelb@gimli.ms.mff.cuni.cz/
RFC v2:

  justify the use of the MFD framework.
