CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

This patch allows the STMPE driver to be successfully probed and
initialised when Device Tree support is enabled. Besides the usual
platform data changes, we also separate the process of filling in
the 'in use' pin bitmap, as we have to extract the information from
Device Tree in the DT boot case.

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFS update from Samuel Ortiz:
"This is the MFD patch set for the 3.8 merge window.
We have several new drivers, most of the time coming with their sub
devices drivers:
- Austria Microsystem's AS3711
- Nano River's viperboard
- TI's TPS80031, AM335x TS/ADC,
- Realtek's MMC/memstick card reader
- Nokia's retu
We also got some notable cleanups and improvements:
- tps6586x got converted to IRQ domains.
- tps65910 and tps65090 moved to the regmap IRQ API.
- STMPE is now Device Tree aware.
- A general twl6040 and twl-core cleanup, with moves to the regmap
I/O and IRQ APIs and a conversion to the recently added PWM
framework.
- sta2x11 gained regmap support.
Then the rest is mostly tiny cleanups and fixes, among which we have
Mark's wm5xxx and wm8xxx patchset."
Far amount of annoying but largely trivial conflicts. Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.

Since the very first patch, stmpe core driver is using irq_invert_polarity as
part of platform data. But, nobody is actually using it in kernel till now.
Also, this is not something part of hardware specs, but is included to cater
some board mistakes or quirks.
So, better get rid of it. This is earlier discussed here:

Historically, a driver would have to decide whether it required
a Linear or Legacy IRQ domain when registering one. This can end
up as quite a lot of code. A new Simple call now exists which
simplifies this process. Let's make use of it here.

Originally IRQ incrementers were provided in some template resource
structures for keypad and touchscreen devices. These were passed as
IORESOURCE_IRQs to MFD core in the usual way. The true device IRQs
were instead added to the irq_base when mfd_add_devices was invoked.
This is clearly an abuse of the call, and does not scale when IRQ
Domains are brought into play. Before we can provide the STMPE with
its own IRQ Domain we must first fix this. This patche keeps most
of the driver's structure, keeping the template strategy. However,
instead of providing the IRQ as an increment to irq_base, we
dynamically populate the IORESOURCE_IRQ with the correct device IRQ.

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

Few STMPE controller can have register interface over SPI or I2C. Current
implementation only supports I2C and all code is present in a single file
stmpe.c. It would be better to separate out I2C interface specific code from
controller specific code. Later SPI specific code can be added in a separate
file.
This patch separates out I2C and controller specific code into separate files,
making stmpe.c independent of I2C.
