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, kind regards,

v7:
- Rebase to v6.10-rc1.
- v6: https://lore.kernel.org/r/20240504194632.2456-1-balejk@matfyz.cz/
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.
