This makes the AB8500 state struct contain the IRQ mask and
register offsets previously hard-coded so as to make room for
more AB8500 variants.

There are currently four different versions of the AB8500
around: AB8500, AB8505, AB9540 and AB8540. Unfortunately:
- Some of the chips (AB8500, AB8505, AB9540) cannot read
the AB8500_REV_REG register but return errors
- Some of them have the same ID value in the hardware
register AB8500_REV_REV, for example the first versions
of AB8505 and AB9540 have 0xFF in this register -
just like the AB8500.
So we need to be able to enforce a certain version from
the platform. We do this by using the id of the platform
device that provides the read/write functions.

The gpio_to_irq() macro is now defined as __gpio_to_irq() instead of IRQ_GPIO().
The __gpio_to_irq() function returns -ENXIO if the referenced gpio_chip
structure does not define a to_irq() member.
This is true of the asic3 gpio_chip structure, and thus calls to gpio_to_irq()
now fail (for example from the gpio-vbus module).
This patch defines the to_irq() member in the asic3 gpio_chip structure.

This patch adds an initial PRCMU register access API, which
for now should only be used for a very limited set of registers.
The idea about this API is that we split the PRCMU driver in
one part that deals with interaction with the PRCMU firmware
and one part that simply provide write accessors in the PRCMU
register range. The latter are just a collection of registers
exposed in the PRCMU register range for various purposes and
not related to the PRCMU firmware.
Currently we support some limited GPIO, SPI and UART settings
through this API.

As drivers have progressed and got some more review we have
consequently moved things around:
- Some device drivers have changed name and some were wrong
from the beginning.
- We removed the dependency from some domains to the VAPE
domain - SIA MMDSP, SIA PIPE, SVA MMDSP and SVA PIPE power
domains are handled outside the framework while ESRAM12
and ESRAM34 are actually handled inside the PRCMU.

This updates the clock handling in the DB8500 PRCMU driver with
the latest findings and API changes related to changes in the
backing firmware in the PRCMU.
- Add the necessary interfaces to get the frequencies of the
clocks and set the rate of some of the clocks.
- Add support for controlling the clocks PLLSOC0, PLLDSI,
DSI0, DSI1 and DSI escape clocks (DSInESCCLK).
- Correct the PLLSDI enable/disable sequence by using the
DSIPLL_CLAMPI bit.
After this we will have the interfaces and code to implement the
U8500 clock framework properly.

Add __devinit annotation for da9052_spi_probe to fix below build warning:
WARNING: drivers/built-in.o(.text+0x349b4): Section mismatch in reference from the function da9052_spi_probe() to the function .devinit.text:da9052_device_init()
The function da9052_spi_probe() references
the function __devinit da9052_device_init().
This is often because da9052_spi_probe lacks a __devinit
annotation or the annotation of da9052_device_init is wrong.
Also add __devexit annotation for da9052_spi_remove because we have
__devexit_p around it in the remove callback.

This set of changes are fixing various section mismatch warnings which
look to be completely valid. Primerily, those which are fixed are those
which can cause oopses by manipulation of driver binding via sysfs. For
example: calling code marked __init from driver probe __devinit
functions.
Some of these changes will be reworked at the next merge window when the
underlying reasons are sorted out. In the mean time, I think it's
important to have this fixed for correctness.
Also included in this set are fixes to various error messages in OMAP -
including making them gramatically correct, fixing a few spelling
errors, and more importantly, making them greppable by unwrapping them.
Tony Lindgren has acked all these patches, put them out for testing a
week ago, and I've tested them on the platforms I have.

In commit aeb5032b3f, a dependency on IRQ_DOMAIN was added, which causes
regressions on previously working setups: a previously working non-DT
kernel configuration now loses its PMIC support. The lack of PMIC
support in turn causes the loss of other functionality the kernel had.
This dependency was added because the driver now registers its
interrupts with the IRQ domain code, presumably to prevent a build error.
The result is that OMAP3 oopses in the vp.c code (fixed by a previous
commit) due to the lack of PMIC support.
However, even with IRQ_DOMAIN enabled, the driver oopses:

This happens because we try to register an IRQ domain with a NULL ops
structure, and the first thing irq_domain_add() does is try to
dereference this ops structure.
So, fix the problem by getting rid of the incorrect OF_IRQ ifdef and
wrapping the IRQ domain bits of the driver with an IRQ_DOMAIN ifdef
instead.

Do not reconfigure the PLL in case it has been configured already
with the requested parameters.
In case of different PLL configuration do only the needed changes.
This can save considerable amount of time since we can avoid the
defined protocol (with delays) for the PLL configuration.

If the ucb1x00 touchscreen is resumed while the touchscreen is being
touched, the main thread stops responding. This occurs because two
things happen:
1. When we suspended, we were woken up, and executed the loop.
Finding that the touchscreen was not pressed, we prepare to
schedule for a maximum timeout, before being stopped in
try_to_freeze().
2. an irq occurs, we disable the irq, and mark it as disabled,
and wake the thread. This wake occurs while the thread is
still within __refrigerator()
3. The thread is unfrozen, and __refrigerator() sets the threads
state back to INTERRUPTIBLE.
We then drop into schedule_timeout() with an infinite timeout and the
IRQ disabled. This prevents any further screen touches activating
the thread.
Fix this by using kthread_freezable_should_stop() which handles the
freezing issues for us outside of the hotspot where the task state
matters. Include a flag to ignore the touchscreen until it is
released to avoid sending unintended data to the application.

gpiolib drivers should first set the output data before setting the
direction to avoid putting glitches on an output signal. As an
additional bonus, we tweak the code to avoid unnecessary register
writes to the output and direction registers if they have no need
to be updated.

We were not restoring the UCB1x00 gpio output data on resume, resulting
in incorrect GPIO output data after a resume. Add the missing register
write.

The genirq layer complains if an interrupt handler returns with
interrupts enabled. The UCB1x00 handler does just this, because
ucb1x00_enable() calls mcp_enable(), which uses spin_lock_irq()
rather than spin_lock_irqsave(). Convert this, and the divisor
setting functions to use spin_lock_irqsave().

This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7.
Conflicts:
scripts/mod/file2alias.c
This change is wrong on many levels. First and foremost, it causes a
regression. On boot on Assabet, which this patch gives a codec id of
'ucb1x00', it gives:
ucb1x00 ID not found: 1005
0x1005 is a valid ID for the UCB1300 device.
Secondly, this patch is way over the top in terms of complexity. The
only device which has been seen to be connected with this MCP code is
the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same
driver. Adding a match table, requiring the codec string to match the
hardware ID read out of the ID register, etc is completely over the top
when we can just read the hardware ID register.
