Lee Jones bad76991d7 mfd: Register ab8500 devices using the newly DT:ed MFD API
Now the MFD API is Device Tree aware we can use it for platform
registration again, even when booting with DT enabled. To aid in
Device Node pointer allocation we provide each cell with the
associative compatible string.

Lee Jones 822672a7b4 mfd: Generically describe interactions with the DB8500 PRCMU
There is only one method used to communicate with the DB8500 PRCMU, via I2C.
Now this can be assumed, there is no requirement to specify the protocol in
the function name. This patch removes protocol specifics and uses a more
generic naming convention.

Linus Walleij ee66e653ca mfd: Unify abx500 headers in mfd/abx500
This moves all the header files related to the abx500 family into
a common include directory below mfd. From now on we place any
subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface
remains in <linux/mfd/abx500.h>.

Paul Gortmaker 4e36dd3314 mfd: Add module.h to the implicit drivers/mfd users
With the pending module.h cleanup, these files will fail to compile,
unless they explicitly call out the include of this file.

Peter Huewe 8504d63804 mfd: Use kstrtoul_from_user in ab8500
This patch replaces the code for getting an unsigned long from a
userspace buffer by a simple call to kstroul_from_user.
This makes it easier to read and less error prone.

Mark Brown 87fff232cb mfd: Use NULL to initialise NULL pointers in ab8500-debugfs
Partly for coding style reasons, but mostly because sparse warns on it.

Mattias Wallin 5814fc35e1 mfd: AB8500 debugfs
This patch adds the possibility to read and write registers
via the debug_fs. It also adds ranges of registers sorted by bank
which makes it possible to read all defined registers in a bank.
