When compiling the AB8500 core driver in the latest
MFD tree the following happens:
CC drivers/mfd/ab8500-debugfs.o
/home/elinwal/linux-next/drivers/mfd/ab8500-debugfs.c:157:3: error: 'AB8500_SYS_CTRL1_BLOCK' undeclared here (not in a function)
/home/elinwal/linux-next/drivers/mfd/ab8500-debugfs.c:157:2: error: array index in initializer not of integer type
/home/elinwal/linux-next/drivers/mfd/ab8500-debugfs.c:157:2: error: (near initialization for 'debug_ranges')
(...)
This is due to a missing include statement, so fix
it up.

The new format of ab8500_gpadc_get() accepts a device name as a
parameter to specify which device to retrieve. This patch
enforces the use of that new format.

With the introduction of new AB* platforms, it's important to allow
as much code reuse as possible. By allowing a system's number of IRQs
to be dynamically passed, we can reuse almost all of the -debugfs
driver.

In case of AB-V3, the eye diagram related issues are resolved.
So, set the device charging current to 300mA when connected to
standard host. Also, add the USB PHY tuning values to improve
the USB eye diagram

Add debugfs entry ab8500/hwreg to read/write bit-field in AB8500 registers.
Check the debugfs entries usage from heading comments in ab8500-debugfs.c

Partly for coding style reasons, but mostly because sparse warns on it.
This patch is a completion of a previous patch by Mark Brown.

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.

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.

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>.

With the pending module.h cleanup, these files will fail to compile,
unless they explicitly call out the include of this file.

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.
