Subject: [RFC PATCH 0/5] support for Marvell 88PM886 PMIC
From: Karel Balej <balejk@...fyz.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 driver is based on the latter. I am not in possesion of
the datasheet.
The vendor version of this driver includes support for a similar chip:
88PM880. While that is not included here it was written with it in mind
and it should be quite straighforward to add it.

Thank you and kind regards,
K. B.
