863dde5bfa mfd: Provide ab8500-core enumerators for chip cuts
Since functionality in MFD cells may need to be adjusted according to
chip revision, let's enumerate them and keep track of them.

0cb3fcd72c gpio: driver for 42 AB8500 GPIO pins
To get rid of port expanders, the free GPIOs of ab8500
can be used. There are 42 GPIO pins. Out of which 16
are interrupt capable.This patch implements 16 virtual
IRQ mapped to 16 interrupt capable AB8500 GPIOs.

e5c238c3fd mfd: ab8500-core switch off status added
This patch adds a sysfs file with the ab8500 switch off status.
The switch off status contains information of what caused the ab8500
chip to power off. A print during boot is also added.

47c1697508 mfd: Align ab8500 with the abx500 interface
This patch makes the ab8500 mixed signal chip expose the same
interface for register access as the ab3100, ab3550 and ab5500 chip.
The ab8500_read() and ab8500_write() is removed and replaced with
abx500_get_register_interruptible() and
abx500_set_register_interruptible().

62579266cf mfd: New AB8500 driver
Add a new driver to support the AB8500 Power Management chip, replacing
the current AB4500.  The new driver replaces the old one, instead of an
incremental modification, because this is a substantial overhaul
including:

 - Split of the driver into -core and -spi portions, to allow another
   interface layer to be added

 - Addition of interrupt support

 - Switch to MFD core API for handling subdevices

 - Simplification of the APIs to remove a redundant block parameter

 - Rename of the APIs and macros from ab4500_* to ab8500_*

 - Rename of the files from ab4500* to ab8500*

 - Change of the driver name from ab4500 to ab8500
