618fa57512 mfd: 88pm800: Fix NULL pointer dereference
Move "device_800_init" to fix NULL pointer error when
calling "device_gpadc_init" as it needs "subchip->regmap_gpadc"
to set registers via regmap interface

d8c5d658f4 A complete refurbished series inclunding:
- DT support for the MFD, TSC and ADC driver & platform device support,
   which has no users, has been killed.
 - iio_map from last series is gone and replaced by proper nodes in the
   device tree.
 - suspend fixes which means correct data structs are taken and no
   interrupt storm
 - fifo split which should problem with TSC & ADC beeing used at the same
   time
 - The ADC channels are now checked before blindly applied. That means the
   touch part reads X, Y and Z coordinates and does not mix them up. Same
   goes for the IIO ADC driver.
 - The IIO ADC driver now creates files named in_voltageX_raw where X
   represents the ADC line instead of a number starting at 0. A read from
   this file can return -EBUSY in case touch is busy and the ADC didn't
   collect a value.

18926edebc iio: ti_am335x_adc: Allow to specify input line
The TSC part allows to specify the input lines. The IIO part assumes
that it usues always the last few, that means if IIO has adc-channels
set to 2 it will use channel 6 and 7. However it might make sense to use
only 6.
This patch changes the device property (which was introduced recently
and was never in an official release) in a way that the user can specify
which of the AIN lines should be used. In Addition to this, the name is
now AINx where x is the channel number i.e. for AIN6 we would have 6.
Prior this, it always started counting at 0 which is confusing. In
addition to this, it also checks for correct step number during reading
and does not rely on proper FIFO depth.

The mfd driver creates platform data for the child devices and it is the
ti_tscadc_dev struct. This struct is copied for the two devices.
The copy of the structure makes a common lock in this structure a little
less usefull. Therefore the platform data is not a pointer to the
structure and the same structure is used.
While doing the change I noticed that the suspend/resume code assumes
the wrong pointer for ti_tscadc_dev and this has been fixed as well.

fa67d4ebc7 mfd: tc6393xb: Remove unnecessary platform_set_drvdata()
The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d06310

5070158804 cpufreq: rename index as driver_data in cpufreq_frequency_table
The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core.  It only is useful
for cpufreq drivers for their internal purposes.

Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.

Rename it to "driver_data" as that's what its purpose is. All of its
users are updated accordingly.

45f0a85c82 PM / Runtime: Rework the "runtime idle" helper routine
The "runtime idle" helper routine, rpm_idle(), currently ignores
return values from .runtime_idle() callbacks executed by it.
However, it turns out that many subsystems use
pm_generic_runtime_idle() which checks the return value of the
driver's callback and executes pm_runtime_suspend() for the device
unless that value is not 0.  If that logic is moved to rpm_idle()
instead, pm_generic_runtime_idle() can be dropped and its users
will not need any .runtime_idle() callbacks any more.

Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle()
routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and
ata_port_runtime_idle(), respectively, as well as a few drivers'
ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has
been returned by the .runtime_idle() callback executed by it.

To reduce overall code bloat, make the changes described above.

 So we have:
 
 - Some build fixes for the tps65912 and ab8500 drivers.
 - A couple of build fixes for the the si476x driver with pre 4.3 gcc
   compilers.
 - A few runtime breakage fixes (probe failures or oopses) for the ab8500

 - Some sparse or regular gcc warning fixes for the si476x, ab8500 and
   cros_ec drivers.

When booting with Device Tree enabled the MFD core uses each device's
compatible string to find and allocate its associated of_node pointer,
which in turn is passed to the driver via the platform_device struct.
Without it, the driver won't be able to interrogate the Device Tree or
locate suitable regulators and will most likely fail to probe.

eb696c3181 mfd: ab8500-core: Use the correct driver name when enabling gpio/pinctrl
When we're using Device Tree to enable GPIO drivers we're forced to be
OS agnostic, thus we are forbidden use names like pinctrl as they are
specific only to Linux, at least for the time being. However, when we
are registering devices using internal systems such as MFD or platform
registration, we can use such terminology. In this case we can and
should use the platform device ID mechanism to specify which device we
wish to utilise by detailing pinctrl-<device_name>.

This patch fixes a regression that when booting with Device Tree
enabled the ABx500 GPIO/Pinctrl devices are not probed.

6999181eec mfd: ab8500: Pass AB8500 IRQ to debugfs code by resource
The AB8500 debug code which was merged in parallell with the
multiplatform work incidentally introduced a new instance using
the <mach/irqs.h> header which is now deleted, causing this
build regression:

drivers/mfd/ab8500-debugfs.c:95:23:
fatal error: mach/irqs.h: No such file or directory
compilation terminated.
make[4]: *** [drivers/mfd/ab8500-debugfs.o] Error 1

The code most certainly never worked with device tree either
since that does not rely on this kind of hard-coded interrupt
numbers.

Fix the problem at the root by passing it as a named resource
from the ab8500-core driver. Use an untyped resource to
stop the MFD core from remapping this IRQ relative to the
AB8500 irqdomain.

c34924b950 mfd: cros_ec_spi: Use %z to format pointer differences
Before commit 5c29e47e6a ("mfd: cros_ec_spi:
Warnings fix"), 64-bit compiles gave the following warnings:

drivers/mfd/cros_ec_spi.c: In function 'cros_ec_spi_receive_response':
drivers/mfd/cros_ec_spi.c:123:5: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long int' [-Wformat]

drivers/mfd/cros_ec_spi.c:181:2: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long int' [-Wformat]

After that commit, 32-bit compiles give:

drivers/mfd/cros_ec_spi.c: In function ‘cros_ec_spi_receive_response’:
drivers/mfd/cros_ec_spi.c:123: warning: format ‘%ld’ expects type ‘long int’, but argument 4 has type ‘int’

Use %z to format pointer differences to kill the warnings on both 32-bit
and 64-bit.

d7ab7302f9 For 3.10 we have a few new MFD drivers for:
- The ChromeOS embedded controller which provides keyboard, battery and power
   management services. This controller is accessible through i2c or SPI.
 
 - Silicon Laboratories 476x controller, providing access to their FM chipset
   and their audio codec.
 
 - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based reader.
 
 - Nokia's Tahvo power button and watchdog device. This device is very similar
   to Retu and is thus supported by the same code base.
 
 - STMicroelectronics STMPE1801, a keyboard and GPIO controller supported by
   the stmpe driver.
 
 - ST-Ericsson AB8540 and AB8505 power management and voltage converter
   controllers through the existing ab8500 code.
 
 Some other drivers got cleaned up or improved. In particular:
 
 - The Linaro/STE guys got the ab8500 driver in sync with their internal code
   through a series of optimizations, fixes and improvements.
 
 - The AS3711 and OMAP USB drivers now have DT support.
 
 - The arizona clock and interrupt handling code got improved.
 
 - The wm5102 register patch and boot mechanism also got improved.

Mostly many small changes spread as seen in diffstat in sound/*
 directory by this update.  A significant change in the subsystem level
 is the introduction of snd_soc_component, which will help more generic
 handling of SoC and off-SoC components.
 
 Also, snd_BUG_ON() macro is enabled unconditionally now due to its
 misuses, so people might hit kernel warnings (it's a good thing for
 us).

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.

Merge tag 'for-v3.10' of git://git.infradead.org/battery-2.6

Pull battery updates from Anton Vorontsov:
 "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 (ie 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-wide: use devm_kzalloc() where appropriate
   - Tree-wide: 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.

all platforms into a common device structure and the remaining
ones into a platform specific one.

6394678e6e mfd: wm8994: Don't use system PM operations
For realistic systems the power management is controlled entirely via
runtime PM - if the device is not runtime suspended then the suspend
will abort without doing anything as functionality such as accessory
detection or audio bypass will require the device to be enabled while
if the device is runtime suspended it is already in the lowest power
state. This means that system suspend is redundant and can be removed
which avoids issues with attempting to double disable the regulators.

The Kconfig entry for DA9055 PMIC Support selects PMIC_DA9055. That was
probably inspired by the similar select statement in the entry for
DA9052/53 PMIC with I2C. But the DA9055 PMIC only comes in an I2C
variant and its driver doesn't need a separate Kconfig symbol for shared
code. In any case, this select can be dropped as PMIC_DA9055 doesn't
exist.

c4fbec3c6b mfd: palmas: Initialise client->of_node for dummy created client
Palmas device have three different i2c addresses. The device creates
the two new dummy i2c clients for accessing the register by using
primary client adapter. This new dummy i2c client have their of_node
as NULL.

The dummy i2c client is used for registering interrupt and on this,
it creates irq domain handle. This created irq domain handle has
their of_node as NULL.

Now when any child of this device is registered through the DT as
follows:
         palmas: tps65913@58 {
         	::::::::::::::::::

         	#interrupt-cells = <2>;
                interrupt-controller;

                palmas_rtc {
                       compatible = "ti,palmas-rtc";
                       interrupt-parent = <&palmas>;
                       interrupts = <8 0>;
                };
                ::::::::::;;;
         };

And child driver (palam-rtc in this case) get their irq number as
	irq = platform_get_irq(pdev, 0);

The returned irq number is error in this case. The reason is that
the created irq_domain handle for the palmas interrupt does not have
valid node and so matching of node fails with palmas node.

Hence initialising the newly dummy created client->of_node with the
primary clients of_node so that irq_domain handle have proper of_node
for matching.

Driver twl4030-madc has hardcoded channel types (10 - battery current,
1 - battery temperature) and also conversation data in variable
twl4030_divider_ratios. These hardcoded channels are incorrect for
Nokia RX-51 board (where is channel 0 - battery temperature).

For Nokia RX-51 there is rx51_battery power_supply driver which reporting
battery information via twl4030_madc_conversion. But this driver needs
raw values (not converted via some hardcoded functions). So this patch
adding new parameter "raw" to struct twl4030_madc_request which tell

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.

'patch_regs' cannot be used uninitialized in wm8994_device_init(),

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().

441a499e5a Merge branch 'for-mfd-and-power' of git://git.linaro.org/people/ljones/linux-3.0-ux500
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.

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.

ab7826595e This is the MFD pull request for the 3.9 merge window.
No new drivers this time, but a bunch of fairly big cleanups:
 
 - Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation,
   OMAP5 support and clock management code cleanup.
 
 - The first step of a major sync for the ab8500 driver from Lee Jones. In
   particular, the debugfs and the sysct interfaces got extended and improved.
 
 - Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core
   driver, with a much needed module id lookup code improvement.
 
 - The regular wm5102 and arizona cleanups and fixes from Mark Brown.
 
 - Laxman Dewangan extended the palmas APIs in order to implement the palmas
   GPIO and rt drivers.
 
 - Laxman also added DT support for the tps65090 driver.
 
 - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and
   Darren Hart.
 
 - Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based
   devices to switch to the new abx500 pin-ctrl driver.
 
 - The max8925 now has device tree and irqdomain support thanks to Qing Xu.
 
 - The recently added rtsx driver got a few cleanups and fixes for a better
   card detection code path and now also supports the RTS5227 chipset, thanks
   to Wei Wang and Roger Tseng.

5ce7aba976 arm-soc: driver specific changes
* Updates to the ux500 cpufreq code
 * Moving the u300 DMA controller driver to drivers/dma
 * Moving versatile express drivers out of arch/arm for sharing with arch/arm64
 * Device tree bindings for the OMAP General Purpose Memory Controller
 
 There is a simple conflict in drivers/cpufreq/dbx500-cpufreq.c, because
 the mach/id.h header and the cpu_is_u8500_family() function in it are
 now gone.

b274776c54 arm-soc: cleanups
A large number of cleanups, all over the platforms. This is dominated
 largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
 others moving code out of arch/arm into more appropriate subsystems.
 The clocksource and irqchip drivers are now abstracted to the point
 where platforms that are already cleaned up do not need to even specify
 the driver they use, it can all get configured from the device tree
 as we do for normal device drivers. The clocksource changes basically
 touch every single platform in the process.
 
 We further clean up the use of platform specific header files here,
 with the goal of turning more of the platforms over to being
 "multiplatform" enabled, which implies that they cannot expose
 their headers to architecture independent code any more.
 
 It is expected that no functional changes are part of the cleanup.
 The overall reduction in total code lines is mostly the result of
 removing broken and obsolete code.

Bug fixes that did not make it into v3.8, mostly because they were not

 This includes a few larger patches for GPIO on the Marvell PXA platform
 and a lot of Samsung specific bug fixes, as well as a series from Arnd
 to fix older build warnings.
