Add gpio support for Intel MSIC chips found in Intel Medfield platforms.
MSIC supports totally 24 GPIOs with 16 low voltage and 8 high voltage pins.
Driver uses MSIC mfd interface for MSIC access.
(Updated comment to indicate why locking is actually safe)

Only code move, no functional change.
Main reason to do this was to get rid of the warnings:
drivers/gpio/gpio-samsung.c: In function 'samsung_gpiolib_init':
drivers/gpio/gpio-samsung.c:2974:1: warning: label 'err_ioremap4' defined but not used [-Wunused-label]
drivers/gpio/gpio-samsung.c:2722:47: warning: unused variable 'gpio_base4' [-Wunused-variable]
without adding more ifdef mess.
I think this whole file would do well being coverted over to a platform
driver and moving most of the tables out to SoC code and/or device trees,
but since that changes init ordering it needs to be done with some care,
i.e. not at this time.

The IRQ status register should be re-read after each iteration.
Otherwise the loop misses the interrupt if it gets raised immediately

Initialization of irqenable, irqstatus registers is the common
operation done in this function for all OMAP platforms, viz. OMAP1,
OMAP2+. The latter _gpio_rmw()'s which supposedly got introduced
wrongly to take care of OMAP2+ platforms were overwriting initially
programmed OMAP1 value breaking functionality on OMAP1.
Somehow incorrect assumption was made that each _gpio_rmw()'s were
mutually exclusive. On close observation it is found that the first
_gpio_rmw() which is supposedly done to take care of OMAP1 platform
is generic enough and takes care of OMAP2+ platform as well.
Therefore remove the latter _gpio_rmw() to irqenable as they are
redundant now.
Writing to ctrl and debounce_en registers for OMAP2+ platforms are
modified to match the original(pre-cleanup) code where the registers
are initialized with 0. In the cleanup series since we are using
_gpio_rmw(reg, 0, 1), instead of __raw_writel(), we are just reading
and writing the same values to ctrl and debounce_en. This is not an
issue for debounce_en register because it has 0x0 as the default value.
But in the case of ctrl register the default value is 0x2 (GATINGRATIO
= 0x1) so that we end up writing 0x2 instead of intended 0 value.
Therefore changing back to __raw_writel() as this is sufficient for
this case besides simpler to understand.
Also, change irqstatus initalization logic that avoids comparison
with bool, besides making it fit in a single line.

This driver works on many Intel chipsets, including the ICH6, ICH7,
ICH8, ICH9, ICH10, 3100, Series 5/3400 (Ibex Peak), Series 6/C200
(Cougar Point), and NM10 (Tiger Point).
Additional Intel chipsets should be easily supported if needed, eg the
ICH1-5, EP80579, etc.
Tested on QM67 (Cougar Point), QM57 (Ibex Peak), 3100 (Whitmore Lake),
and NM10 (Tiger Point).
Includes work from Jean Delvare:
- Resource leak removal during module load/unload
- GPIO API bit value enforcement
Also includes code cleanup from Guenter Roeck and Grant Likely.

In 3.3, gpio wakeup setting was broken. The call
enable_irq_wake() didn't set up the PXA gpio registers
(PWER, ...) anymore.
Fix it at least for pxa27x. The driver doesn't seem to be
used in pxa25x (weird ...), and the fix doesn't extend to
pxa3xx and pxa95x (which don't have a gpio_set_wake()

When a Tegra GPIO is used as an IRQ, it should be enabled as a GPIO (so
the pinmux module isn't driving it as an output) and configured as a GPIO
input (so the GPIO module isn't driving it as an output). Set this up
automatically whenever an IRQ is requested, so that users of IRQs don't
need to do this.

"This covers platform stuff for platforms I have a direct interest in

- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0

- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA

- rework sa1111 support for genirq, and irq allocation

Pull "ARM: global cleanups" from Arnd Bergmann:
"Quite a bit of code gets removed, and some stuff moved around, mostly
the old samsung s3c24xx stuff. There should be no functional changes
in this series otherwise. Some cleanups have dependencies on other
arm-soc branches and will be sent in the second round.

both sides.

The sodaville driver doesn't build anymore due to the transition to
common irq_domain in the core code. It needs to be reworked, but
the rework isn't trivial. Since this is a new driver anyway for
v3.4, mark it as broken now and a fixup patch can re-enable it when
the rework change has been tested.

twl4030 is using a two level irq controllers infrastruture.
So far, only the first level was using dynamic irq_desc allocation
to be able to have irq_domain support for device tree.
There is a need to allocate separate irq_descs for the SIH too to
avoid hacking the first level with interrupts from the second level.
Add an irq_base parameter to allow the caller to provide the base from
pdata or from dynamic allocation.
Affect TWL4030_NR_IRQS to the twl-core IRQs only.
Moreover that will allow the extraction of the of_node pointer for further
Device Tree conversion.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc merge from Benjamin Herrenschmidt:
"Here's the powerpc batch for this merge window. It is going to be a
bit more nasty than usual as in touching things outside of
arch/powerpc mostly due to the big iSeriesectomy :-) We finally got
rid of the bugger (legacy iSeries support) which was a PITA to
maintain and that nobody really used anymore.
Here are some of the highlights:
- Legacy iSeries is gone. Thanks Stephen ! There's still some bits
and pieces remaining if you do a grep -ir series arch/powerpc but
they are harmless and will be removed in the next few weeks
hopefully.
- The 'fadump' functionality (Firmware Assisted Dump) replaces the
previous (equivalent) "pHyp assisted dump"... it's a rewrite of a
mechanism to get the hypervisor to do crash dumps on pSeries, the
new implementation hopefully being much more reliable. Thanks
Mahesh Salgaonkar.
- The "EEH" code (pSeries PCI error handling & recovery) got a big
spring cleaning, motivated by the need to be able to implement a
new backend for it on top of some new different type of firwmare.
The work isn't complete yet, but a good chunk of the cleanups is
there. Note that this adds a field to struct device_node which is
not very nice and which Grant objects to. I will have a patch soon
that moves that to a powerpc private data structure (hopefully
before rc1) and we'll improve things further later on (hopefully
getting rid of the need for that pointer completely). Thanks Gavin
Shan.
- I dug into our exception & interrupt handling code to improve the
way we do lazy interrupt handling (and make it work properly with
"edge" triggered interrupt sources), and while at it found & fixed
a wagon of issues in those areas, including adding support for page
fault retry & fatal signals on page faults.
- Your usual random batch of small fixes & updates, including a bunch
of new embedded boards, both Freescale and APM based ones, etc..."
I fixed up some conflicts with the generalized irq-domain changes from
Grant Likely, hopefully correctly.
