Subject: [RFC PATCH v4 0/5] initial 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 and regulators drivers are based on the latter. I am not
in possesion of the datasheet.

Thank you and kind regards,
K. B.
