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.
