From: Karel Balej <balejk@matfyz.cz>
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.
[1] https://lore.kernel.org/all/1434098601-3498-1-git-send-email-yizhang@marvell.com/
[2] https://github.com/CoderCharmander/g361f-kernel
Thank you and kind regards,
K. B.
---
RFC v2:
- Merge with the regulators series to have multiple devices and thus
justify the use of the MFD framework.
- Rebase on v6.8-rc3.
- Reorder patches.
- MFD RFC v1: https://lore.kernel.org/all/20231217131838.7569-1-karelb@gimli.ms.mff.cuni.cz/
- regulators RFC v1: https://lore.kernel.org/all/20231228100208.2932-1-karelb@gimli.ms.mff.cuni.cz/
