From: Karel Balej <balejk@xxxxxxxxx> 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.
