4c4b8c105a mfd: rtsx: Support RTS5249
RTS5249 supports SD UHS-II interface.

In order to support SD UHS-II,the definitions of some internal
registers of RTS5249 have to be modified and are different from its
predecessors. So we need this patch to ensure RTS5249 can work, even
SD/MMC stack doesn't support UHS-II interface.

d98a5384d7 mfd: db8500-prcmu: Support platform dependant device selection
The main aim for this cycle is to have the u8540 booting to a
console. However, the u8540 doesn't support all of the u8500
platform devices yet. After this stage is complete we can then
fill in the inadequacies, such as specific clock support at a
later date. To achieve this we're placing devices supported by
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.

variant and its driver doesn't need a separate Kconfig symbol for shared

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.

a5055d5d68 mfd: twl4030-madc: Add support for raw value in twl4030_madc_conversion
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
twl4030-madc driver to not convert values, but rather return raw.

* 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.

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.

5a324acfce mfd: cros_ec: Add MFD_CORE dependency
CONFIG_MFD_CROS_EC requires CONFIG_MFD_CORE for a couple of functions that
are declared but not defined:

	ERROR: "mfd_remove_devices" [drivers/mfd/cros_ec.ko] undefined!
	ERROR: "mfd_add_devices" [drivers/mfd/cros_ec.ko] undefined!

Fix it by selecting CONFIG_MFD_CORE anytime CONFIG_MFD_CROS_EC is enabled.

[    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.

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.

c7ebaee292 mfd: ab8500-debugfs: Dump sim registers
This patch allows to dump the SIM registers from debugfs. It will
temporary change the config to allow APE side to read the SIM registers.
Note that this read can cause problem on modem side since the modem
can't read these registers while the operation is ongoing.

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.

Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Arnd Bergmann:
 "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."

b24174b0cb arm-soc: non-critical bug fixes
Bug fixes that did not make it into v3.8, mostly because they were not
 considered important enough, and in some cases because bugs only show
 up in combination with other patches destined for 3.9.
 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.

5829e9b64e mfd: lpc_sch: Accomodate partial population of the MFD devices
The current probe aborts if any of the 3 base address registers are
disabled. On a TunnelCreek system I am working on, this resulted in the
SMBIOS and GPIO devices being removed when it couldn't read the base
address for the watchdog timer.

This patch accommodates partial population of the lpc_sch_cells array and
only aborts if all the base address registers are disabled. A max size
array is allocated and the individual device cells are added to it after
their base addresses are successfully determined. This simplifies the
code a bit by removing the need for the separate tunnelcreek cells array
and combining some of the add/remove logic.

1765dbccaa mfd: twl-core: Fix kernel panic on boot
Commit 8a6aaa3 (mfd: twl-core: Collect global variables behind one
private structure (global)) removed the variable "inuse" that is used
to determine if the device has been initialised and now use the
twl_priv structure instead. This is causing the kernel to panic on
OMAP3+ devices using the twl driver, because we try to access the
twl_priv->ready member before checking if twl_priv is initialised. Fix
this and move this test to the beginning of the twl_i2c_read/write
function because twl_get_last_module() also uses the twl_priv structure.

c3481955f6 mfd: rtsx: Fix issue that booting OS with SD card inserted
Realtek card reader supports both SD and MS card. According to the
settings of rtsx MFD driver, SD host will be probed before MS host.
If we boot/reboot Linux with SD card inserted, the resetting flow of SD
card will succeed, and the following resetting flow of MS is sure to fail.
Then MS upper-level driver will ask rtsx driver to turn power off. This
request leads to the result that the following SD commands fail and SD card
can't be accessed again.

In this commit, Realtek's SD and MS host driver will check whether the card
that upper driver requesting is the one existing in the slot. If not, Realtek's
host driver will refuse the operation to make sure the exlusive accessing
at the same time.

dc781d0e10 mfd: arizona: Disable interrupts during resume
Runtime power management does not function during system suspend but the
Arizona devices need to use runtime power management to power up the device
in order to handle interrupts. Try to avoid interrupts firing during
resume by disabling the primary IRQ before interrupts are reenabled on
resume and only reenabling it again during main resume.

The goal is to avoid issues in the situation where an interrupt is asserted
during resume (eg, due to it being the wake source) and the interrupt
handling gets scheduled prior to the device being able to handle runtime
PM.

05ec260ede mfd: db8500-prcmu: update resource passing
When trying to get rid of the cross-includes of <mach/id.h>
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.

This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.

Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from <mach/*> files. Incidentally this also
removes part of the reliance on <mach/irqs.h>.

Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.

The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.

40f6e5a2b5 mfd: ab8500: provide a irq_set_type() function
In the AB8500 IRQ mask and unmask functions, we rely on testing for
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING interrupts to
physically mask and unmask the correct interrupt lines. In order
for us to do that, the trigger needs to be set in the associated
flags. However, unless a irq_set_type() function pointer is passed
when registering the IRQ chip, the IRQ subsystem will refuse to do
it. For that reason, we're providing one.

e2ddf46ab4 mfd: ab8500: actually handle the AB8500 GPIO IRQs correctly
The patch:
"mfd: ab8500: prepare to handle AB8500 GPIO's IRQs correctly"
altered the AB8500 IRQ mask/unmask functions such that they
would handle masking on/off the falling edge IRQ if this was
requested by the consumer. However the bit mask for hwirqs
43 and 44 was shifting the bit mask incorrectly, resulting in
the wrong IRQ being mased/unmasked.

Further while the patch would mask/unmask the correct line,
when the interrupt actually came in, it would still be treated
as a valid hwirq. The offsetting applied when masking/unmasking
was not applied when handling the IRQ, i.e. the falling edge
lines were not routed back to the rising edge lines.

This fixes both cases. The end result has been tested with
the SIM detect IRQ, GPIO12, hwirq 46 and 62.

9c677b9b74 mfd: ab8500: prepare to handle AB8500 GPIO's IRQs correctly
In an upcoming patch, the gpio-ab8500 driver will relinquish all
IRQ handling capability and pass it back into the AB8500 core
driver. This will aid in reducing massive code duplication within
the kernel. Also, most of the functionality is already in the
AB8500 core driver, as the GPIO IRQs are actually sandwiched
between lots of other IRQs which the core driver already handles.

All we're doing here is providing the core driver with knowledge
that each GPIO has two IRQs assigned to it; one for rising and
a separate one for falling.

0a8c290ac5 mfd: da9052/53 lockup fix
An issue has been reported where the PMIC either locks up or fails to
respond following a system Reset. This could result in a second write
in which the bus writes the current content of the write buffer to address
of the last I2C access.

The failure case is where this unwanted write transfers incorrect data to
a critical register.

This patch fixes this issue to by following any read or write with a dummy read
to a safe register address. A safe register address is one where the contents
will not affect the operation of the system.

If charging is started before USB enumeration of an Accessory
Charger Adapter has finished, the AB8500 will generate a
VBUS_ERROR. This in turn results in timeouts and delays the
enumeration with around 15 seconds. This patch delays the
charging and then ramps currents slowly to avoid VBUS errors.
The delay allows the enumeration to have finished before
charging is turned on.

1f0529b4d8 mfd: tc3589x: Use simple irqdomain
This fixes a regression in the TC3589x driver introduced in
commit 15e27b1088
"mfd: Provide the tc3589x with its own IRQ domain"

If a system with a TC3589x expander is booted and a base
IRQ is passed from platform data, a legacy domain will
be used. However, since the Ux500 is now switched to use
SPARSE_IRQ, no descriptors get allocated on-the-fly,
and we get a crash.

Fix this by switching to using the simple irqdomain that
will handle this uniformly and also allocates descriptors
explicitly.

Also fix two small whitespace errors in the vicinity while
we're at it.

89d9b1c993 mfd: db8500-prcmu: Fix irqdomain usage
This fixes two issues with the DB8500 PRCMU irqdomain:
- You have to state the irq base 0 to get a linear domain
  for the DT case from irq_domain_add_simple()
- The irqdomain was not used to translate the initial irq
  request using irq_create_mapping() making the linear
  case fail as it was lacking a proper descriptor.

I took this opportunity to fix two lines of whitespace
errors in related code as I was anyway messing around with
it.

 - Nano River's viperboard
 - TI's TPS80031, AM335x TS/ADC,
 - Realtek's MMC/memstick card reader
 - Nokia's retu
 
 We also got some notable cleanups and improvements:
 
 - tps6586x got converted to IRQ domains.
 - tps65910 and tps65090 moved to the regmap IRQ API.
 - STMPE is now Device Tree aware.
 - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ
   APIs and a conversion to the recently added PWM framework.
 - sta2x11 gained regmap support.
 
 Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
 wm5xxx and wm8xxx patchset.

   - tps6586x got converted to IRQ domains.
   - tps65910 and tps65090 moved to the regmap IRQ API.
   - STMPE is now Device Tree aware.
   - A general twl6040 and twl-core cleanup, with moves to the regmap
     I/O and IRQ APIs and a conversion to the recently added PWM
     framework.
   - sta2x11 gained regmap support.

  Then the rest is mostly tiny cleanups and fixes, among which we have
  Mark's wm5xxx and wm8xxx patchset."

Far amount of annoying but largely trivial conflicts.  Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.

63b68901df mfd: omap-usb-host: get rid of cpu_is_omap..() macros
Instead of using cpu_is_omap..() macros in the device driver we
rely on information provided in the platform data.

The only information we need is whether the USB Host module has
a single ULPI bypass control bit for all ports or individual bypass
control bits for each port. OMAP3 REV2.1 and earlier have the former.

Here are more patches in the progression towards multiplatform, sparse
 irq conversions in particular.
 
 Tegra has a handful of cleanups and general groundwork, but is
 not quite there yet on full enablement.
 
 Platforms that are enabled through this branch are VT8500 and Zynq. note
 that i.MX was converted in one of the earlier cleanup branches as
 well (before we started a separate topic for multiplatform). And both
 new platforms for this merge window, sunxi and bcm, were merged with
 multiplatform support enabled.

d027db132b ARM: arm-soc: SoC updates for 3.8
This contains the bulk of new SoC development for this merge window.
 
 Two new platforms have been added, the sunxi platforms (Allwinner A1x
 SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
 series of ARMv7 platforms from them, where the hope is that we can
 keep the platform code generic enough to have them all share one mach
 directory. The new Broadcom platform is contributed by Christian Daudt.
 
 Highbank has grown support for Calxeda's next generation of hardware,
 ECX-2000.
 
 clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
 taken on maintainership of the platform.
 
 Beyond this there has been a bunch of work from a number of people on
 converting more platforms to IRQ domains, pinctrl conversion, cleanup
 and general feature enablement across most of the active platforms.

 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,

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.

23a04f9f40 ab8500_bm: Always send platform specific battery information via pdata
Currently the AB8500 battery management subsystem receives platform
specific information via two different means depending on how the
platform is booted. If DT is not enabled, a reference to a *_bm_data
data structure containing each platform specific attribute is passed
though platform_data. However, if DT is enabled, then platform_data
is empty and the reference is gained though a DT specific probe
function. There are two issues here 1) the same reference is
being collected each time and 2) the DT way doesn't allow any
provisions to select different platform specific attributes, which
kind of defeats the object.

62d62b59bd mfd: arizona: Defer patch initialistation until after first device boot
Make sure that we don't race with the initial device boot by only doing
the initialisation after we've waited for the boot to complete.

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.

86605cfe8c gpio: stmpe: Add DT support for stmpe gpio
This patch allows the STMPE GPIO driver to be successfully probed and
initialised when Device Tree support is enabled. Bindings are mentioned in
Documentation too.

0582c0fafc mfd: tps65910: Fix wrong ack_base register
The interrupt status registers of TPS65910/1 should be cleared
when the associated interrupt event occurs.
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.

Tested on the AM3517 Craneboard.

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:

4e1328be4d mfd: ab8500-core: Fix invalid free of devm_ allocated data
The objects allocated by devm_* APIs are managed by devres and are
freed when the device is detached. Hence there is no need to remove
them explicitly in remove function.
