e0f4fec030 mfd: abx500-core: Provide an API to dump all ABx500 registers 
Some drivers can detect subsystem failures e.g. shared memory driver
can detect modem sub system failures. It would be helpful in analyzing
these failures if AB register dump is available at that point. This
patch adds the API for the drivers to dump AB registers in the kernel
log.

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.

25fe24f884 mfd: kzalloc doesn't return ERR_PTR 
Use !x rather than IS_ERR(x) to test the result of kzalloc.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,E;
@@

x = \(kmalloc\|kzalloc\|kcalloc\)(...)
... when != x = E
- IS_ERR(x)
+ !x
// </smpl>

fa661258a2 mfd: AB3100 register access change to abx500 API 
The interface for the AB3100 is changed to make way for the
ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson
Analog Baseband chips. The register access functions are moved
out to a separate struct abx500_ops. In this way the interface
is moved from the implementation and the sub functionality drivers
can keep their interface intact when chip infrastructure and
communication mechanisms changes. We also define the AB3550
device IDs and the AB3550 platform data struct and convert
the catenated 32bit event to an array of 3 x 8bits.
