99c6bcf46d ARM: arm-soc multiplatform updates for 3.10
More multiplatform enablement for ARM platforms. The ones converted in
 this branch are:
 - bcm2835
 - cns3xxx
 - sirf
 - nomadik
 - msx
 - spear
 - tegra
 - ux500
 
 We're getting close to having most of them converted!
 
 One of the larger platforms remaining is Samsung Exynos, and there are
 a bunch of supporting patches in this merge window for it. There was a
 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required
 rebasing multiple dependent branches and they were stable by then.

151173e8ce Highlights:
- OpenFirmware/DeviceTree support for the Power Supply core: the core now
   automatically populates supplied_from hierarchy from the device tree.
   With these patches chargers and batteries can now lookup each other
   without the board files support shim. Rhyland Klein at NVIDIA did the
   work;
 
 - New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the
   AB85xx core and depends on some recent changes to it, so that is why the
   driver comes through the battery tree. It has an appropriate ack from
   the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson
   and Hongbo Zhang at Linaro authored the driver;
 
 - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes
   touch mfd parts, but these were acked by the appropriate MFD maintainer
   (i.e. Samuel Ortiz). Lee Jones at Linaro did most of the work and lead
   the submission process.
 
 Minor changes, but still worth mentioning:
 
 - Battery temperature reporting fix for Nokia N900 phones;
 - Versatile Express poweroff driver moved into drivers/power/reset/.
 - Tree-wise: use devm_kzalloc() where appropriate;
 - Tree-wise: dev_pm_ops cleanups/fixes.

8ded8d4e4f regulator: Updates for v3.10
The diffstat and changelog here is dominated by Lee Jones' heroic
 efforts to sync the ab8500 driver that's been maintained out of tree
 with mainline (plus Axel's cleanup work on the results) but there's a
 few other things here:
 
 - Axel Lin added regulator_map_voltage_ascend() optimising a common
   pattern for drivers using the core code.
 - Milo Kim tought the regulator core to handle regulators sharing an
   enable GPIO, avoiding the need to do hacks to support such systems.
 - Andrew Bresticker added code to handle missing supplies for regulators
   more sensibly for device tree systems, reducing the need for stubbing
   there.
 
 plus the usual batch of driver specific updates and fixes.

8735bc2fe6 regulator: ab3100: device tree support
This implements device tree support for the AB3100 regulators
driver. The initial settings are moved out of platform data
and into the driver for the device tree case, as it appears
that there is no way to supply this as AUXDATA for an I2C
device. The style and bindings are heavily inspired by
Lee Jones' style for AB8500.

55b175d7e6 ARM: ux500: split out prcmu initialization
This untangles the final bits of the prcmu code from the platform
code:

* The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c
  because they are only of local significance.
* u8500_thsens_device goes into the prcmu, because it uses a PRCMU
  IRQ that the platform does not see.
* IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data
  because the PRCMU does not see it.

1e22a8c614 ARM: ux500: move PM-related PRCMU functions to machine
We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.

Basically we are left with the two alternatives of code
placement as:

- arch/arm/mach-ux500/pm.c - this because the code is
  closely related to the GIC, and takes ownership of
  some of the registers from the PRCMU related to this
  PM functionality.

- drivers/mfd/db8500-prcmu-pm.c - because the code is
  affecting stuff in the PRCMU register range. But then
  this code needs to remap and handle GIC registers.

This patch implementation is taking the first approach.

Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.

The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

b047d98127 mfd: db8500-prcmu: get base address from resource
We cannot use a global variable stored in <mach/hardware.h> to
find the base address of the PRCMU. The real resource is already
there from the board, so use this to look up the base address
instead.

Currently the patch is kept minimal so as not to interfere with
other work being done on refactoring this driver, but at a later
point the defines using (prcmu_base + 0xnnn) need to be replaced
by pure offset defined for (0xnnn) and the base inlined with the
readl()/writel() and similar codepaths.

9a47a8dccf mfd: prcmu: pass a base and size with the early initcall
This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.

Going forward this will be removed like this:

- The mailbox subsystem need to be merged.
  http://marc.info/?l=linux-kernel&m=136314559201983&w=2

- At this point the PRCMU clock code can be moved over to the
  ux500 clock driver in drivers/clk/ux500/* and maintained
  there in a decentralized manner.

- This early initcall and PRCMU base parameters become part of
  the ux500_clk_init() call instead.

	ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs

	This patch series covers both ASoC and extcon subsystems and fixes an
	interaction between the HPDET function and the headphone outputs - we
	really shouldn't run HPDET while the headphone is active.  The first
	patch is a refactoring to make the extcon side easier.

ce44bf5b55 SSBI: Remove MSM_ prefix from SSBI drivers
Although the SSBI sub is currently only used on MSM SoCs, it is still
a bus in its own right.  Remove this msm_ prefix from the driver and
it's symbols.  Clients can now refer directly to ssbi_write() and
ssbi_read().

From Lee Jones <lee.jones@linaro.org>:

"Please find the next instalment of the AB8500 Power drivers upgrade. A lot of
work has taken place on the internal development track, but little effort has
gone into mainlining it. There is a large backlog of patches which are in need
of forward-porting, then upstreaming. This patch-set aims to make a large dent
into them."

037154105e mfd: twl4030-madc: Remove __exit_p annotation
4740f73fe5 "mfd: remove use of __devexit" removed the __devexit annotation
on the twl4030_madc_remove function, but left an __exit_p() present on the
pointer to this function. Using __exit_p was as wrong with the devexit in
place as it is now, but now we get a gcc warning about an unused function.

In order for the twl4030_madc_remove to work correctly in built-in code, we
have to remove the __exit_p.

df545d1cd0 mfd: palmas: Provide irq flags through DT/platform data
Currently driver sets the irq type to IRQF_TRIGGER_LOW which is
causing interrupt registration failure in ARM based SoCs as:
[    0.208479] genirq: Setting trigger mode 8 for irq 118 failed (gic_set_type+0x0/0xf0)
[    0.208513] dummy 0-0059: Failed to request IRQ 118: -22

Provide the irq flags through platform data if device is registered
through board file or get the irq type from DT node property in place
of hardcoding the irq flag in driver to support multiple platforms.

Also configure the device to generate the interrupt signal according to
flag type.

eb1f95872a mfd: ab8500-debug: Add explicit dependencies
As I am working on SPARSE_IRQ a number of implicit resource
grabs in the kernel become evident. For example, some includes
like <linux/irqs.h> would implicitly include <mach/irqs.h>
and then from there <mach/db8500-regs.h>.

In many cases it is masking the fact that drivers do not
properly use resources to pass their dependencies, base
addresses etc. So write explicit #include statements with
TODO items to have this fixed the proper way to all drivers
doing this.
