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.

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-bal...@matfyz.cz/ v5: - RFC v4: https://lore.kernel.org/r/20240311160110.32185-1-kar...@gimli.ms.mff.cuni.cz/ - Rebase to v6.9-rc1. - Thank you to everybody for their feedback on the RFC!
