8287361abc ARM: arm-soc: Header cleanups
This is a collection of header file cleanups, mostly for OMAP and AT91,
 that keeps moving the platforms in the direction of multiplatform by
 removing the need for mach-dependent header files used in drivers and
 other places.

6a5971d8fe Char/Misc driver merge for 3.8-rc1
Here is the "big" char/misc driver patches for 3.8-rc1.  I'm starting to
 put random driver subsystems that I had previously sent you through the
 driver-core tree in this tree, as it makes more sense to do so.
 
 Nothing major here, the various __dev* removals, some mei driver
 updates, and other random driver-specific things from the different
 maintainers and developers.
 
 Note, some MFD drivers got added through this tree, and they are also
 coming in through the "real" MFD tree as well, due to some major
 mis-communication between me and the different developers.  If you have
 any merge conflicts, take the ones from the MFD tree, not these ones,
 sorry about that.
 
 All of this has been in linux-next for a while.

cff2f741b8 Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.
 
 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.
 
 All of these have (much to Stephen's annoyance), been in linux-next for
 a while.

The runtime PM code already waits for the boot to complete before it
syncs the register patches so in most systems if a race does occur we will
power down very soon afterwards and recover anyway.

This work is done in the regmap irq thread - using 'ack_base' register.
The ACK registers should be fixed as status register, not mask registers.

This patch fixes the infinite interrupt event problem by clearing
interrupt status registers.

0e5fca8106 mfd: tps65910: Remove unused data
The 'io_mutex' is not used anywhere.
The regmap API supports the mutex internally, so no additional mutex
is required.

And 'domain' private data is unnecessary because the irq domain is
already registered by using regmap_add_irq_chip().

12a5105e04 mfd: stmpe: Get rid of irq_invert_polarity
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:

The irqs are enabled one-by-one in pm core resume_noirq phase.
This leads to situation where the twl4030 primary interrupt
handler (PIH) is enabled before the chained secondary handlers
(SIH). As the PIH cannot clear the pending interrupt, and
SIHs have not been enabled yet, a flood of interrupts hangs
the device.

Fixed the issue by setting the SIH irqs with IRQF_EARLY_RESUME
flags, so they get enabled before the PIH.

afc45898f6 mfd: twl-core: Support for proper PWM drivers
The twl6030-pwm driver is going to be deleted since it was only able to
control the Charging indicator LED on the twl6030 PMIC.
The new set of drivers are going to provide support for both PWMs and PWM
driven LED outputs on TWL4030 and TWL6030 PMICs.
The twl-pwm driver will handle the PWMs (2 instance) while the twl-pwmled
driver is to control the two LED instance on TWL4030 and to charging
indicator LED (1 instance) on TWL6030.

current TWL6030_MODULE_ID1 the kernel will crash early since we have:

 #define TWL6030_MODULE_ID1 0x0E
and
 static struct twl_client twl_modules[4];

Down in the stack we try to get the module by:
struct twl_client	*twl = &twl_modules[chip];

Which is obviously going to do nasty things.

1950c71646 mfd: sta2x11-mfd: Add apb-soc regs driver and factor out common code
A driver for the apb-soc registers is needed by the clock
infrastructure code to configure and control clocks on the sta2x11
chip.

Since some of the functions in sta2x11-mfd.c were almost identical
for the two existing platform devices, the following changes
have been performed to avoid further code duplication while
adding the apb-soc-regs driver:

* The sctl_regs and apbreg_regs fields in struct sta2x11_mfd
have been turned into just one array of pointers accessed by
device index.
* Platform probe methods have become one-liners invoking a
common probe with the device's index as second parameter.
* For loops have been inserted where the same operations
were performed for each of the two bars of a pci device.
* The apbreg_mask and sctl_mask functions were almost identical,
so they were turned into inline functions invoking a common
__sta2x11_mfd_mask() with the platform device's index as last
parameter. To do this, enum sta2x11_mfd_plat_dev has been declared in
sta2x11-mfd.h and more device types have been added to it.
