6f1c1e71d9 mfd: max77686: Convert to use regmap_irq
By using the generic IRQ support in the Register map API, it
is possible to get rid max77686-irq.c and simplify the code.

c03842d89b mfd: Fix cs5535 dependencies
As far as I know, the CS5535 and CS5536 chipsets are companions of the
Geode series of processors, which are 32-bit only. So the CS5535
drivers are not needed on x86-64, except for build testing purpose.

This aligns the dependencies to what FB_GEODE already uses.

Intel Atom E600 series processors. As such, its drivers are only
useful on X86_32.

9e8884872d mfd: davinci: Voicecodec needs regmap_mmio
Without REGMAP_MMIO, building that driver results in a link error:

drivers/built-in.o: In function `davinci_vc_probe':
:(.init.text+0x3c1c): undefined reference to `devm_regmap_init_mmio_clk'

This adds a Kconfig 'select' statement as the usual way to ensure
that REGMAP_MMIO is enabled.

f41716dc52 mfd: STw481x: Allow modular build
This driver depends on I2C, which may be a loadable module.
While you'd probably want both to be built-in in practice,
allowing a modular build avoids possible randconfig link

1c93c725d6 mfd: UCB1x00: Enable modular build
The UCB1200 / UCB1300 driver uses the MCP_SA11X0 driver, which
can be a loadable module, but this results in a link error
when UCB1200 itself is built-in:

drivers/built-in.o: In function `ucb1x00_io_set_dir':
:(.text+0x4a364): undefined reference to `mcp_reg_write'
drivers/built-in.o: In function `ucb1x00_io_write':
:(.text+0x4a3dc): undefined reference to `mcp_reg_write'
drivers/built-in.o: In function `ucb1x00_io_read':
:(.text+0x4a400): undefined reference to `mcp_reg_read'
drivers/built-in.o: In function `ucb1x00_adc_enable':
:(.text+0x4a460): undefined reference to `mcp_enable'
...

This can easily be resolved by making CONFIG_MCP_UCB1200 itself
a tristate option, since that causes Kconfig to track the
dependency correctly.

dcc21cc09e mfd: Add driver for Atmel Microcontroller on iPaq h3xxx
This adds a driver for the Atmel Microcontroller found on the
iPAQ h3xxx series. This device handles some keys, the
touchscreen, and the battery monitoring.

This is a port of a driver from handhelds.org 2.6.21 kernel,
written by Alessandro Gardich based on Andrew Christians
original HAL-driver. It has been heavily cleaned and
converted to mfd-core by Dmitry Artamonow and rewritten
again for the v3.x series kernels by Linus Walleij,
bringing back some of the functionality lost from Andrew's
original driver.

b33cdd283b ARM: vexpress: refine dependencies for new code
The versatile express changes for 3.16 introduced a number of
build regressions for randconfig kernels by not tracking dependencies
between the components right.

This patch tries to rectify that:

* the mach-vexpress code cannot link without the syscfg driver,
  which in turn needs MFD_VEXPRESS_SYSREG
* various drivers call devm_regmap_init_vexpress_config(), which
  has to be exported so it can be used by loadable modules
* the configuration bus uses OF DT helper functions that are not
  available to platforms disable CONFIG_OF
* The sysreg driver exports GPIOs through gpiolib, which can
  be disabled on some platforms.
* The clocksource code cannot be built on platforms that don't
  use modern timekeeping but rely on gettimeoffset.

974cc7b934 mfd: vexpress: Define the device as MFD cells
This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:

* LEDs code has been completely removed and replaced with
  "gpio-leds" nodes in the tree (referencing dedicated
  GPIO subnodes in sysreg - bindings documentation updated);
  this also better fits the reality as some variants of the
  motherboard don't have all the LEDs populated

* syscfg bridge code has been extracted into a separate
  driver (placed in drivers/misc for no better place)

* all the ID & MISC registers are defined as sysconf
  making them available for other drivers should they need
  to use them (and also to the user via /sys/kernel/debug/regmap
  which can be helpful in platform debugging)

compatible matching, more complex, more accurate. Make the
driver depend on OF since all platforms using it are DT-only.

aee2a57c74 mfd: max77836: Add MAX77836 support to max14577 driver
Add Maxim 77836 support to max14577 driver. The chipsets have same MUIC
component so the extcon, charger and regulators are almost the same. The
MAX77836 however has also PMIC and Fuel Gauge.

The MAX77836 uses three I2C slave addresses and has additional interrupts
(related to PMIC and Fuel Gauge). It has also Interrupt Source register,
just like MAX77686 and MAX77693.

The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the
PMIC block. The PMIC block has different I2C slave address and uses own
regmap so another regmap_irq_chip is needed.

Since we have two regmap_irq_chip, use shared interrupts on MAX77836.

This patch adds additional defines and functions to the max14577 MFD core
driver so the driver will handle both chipsets. Also this patch replaces
"0x1 << N" with BIT(N) in defines for register masks.

The pm8xxx-irq.c code is practically mandatory given that the
pm8921-core driver will WARN about it missing and the Kconfig
marks it as default y when a PM8xxx chips is enabled. The only
reason the file was split out was because we planned to support
other pm8xxx chips with different pm8xxx-core.c files. Now that
we have DT on ARM this isn't necessary because we should be able
to support all the ssbi based PM8xxx chips in one driver and one
file with no data bloat. Let's move this code into the only
driver that uses it right now (pm8921) so that it's always compiled when
needed. In the future we can rename pm8921-core.c to something

* Regmap I2C interface for R/W LP3943 registers

* Atomic operations for output pin assignment
  The driver should check whether requested pin is available or not.
  If the pin is already used, pin request returns as a failure.
  A driver data, 'pin_used' is checked when gpio_request() and
  pwm_request() are called. If the pin is available, then pin_used is set.
  And it is cleared when gpio_free() and pwm_free().

* Device tree support
  Compatible strings for GPIO and PWM driver.
  LP3943 platform data is PWM related, so parsing the device tree is

This patch adds all necessary header files and Kbuild plumbing for the
core driver for Silicon Laboratories Si476x series of AM/FM tuner
chips.

The driver as a whole is implemented as an MFD device and this patch
adds a core portion of it that provides all the necessary
functionality to the two other drivers that represent radio and audio
codec subsystems of the chip.

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

exist.

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.

64e481603a mfd: tps6586x: move regulator dt parsing to regulator driver
Moving regulator node parsing to regulator driver in place
of parsing it on mfd driver.
The motivation for this change are:
- MFD core driver should not depends on regulator and able
  to instantiate device without regulator.
- The API for matching regulators are in regulator core and
  it is good that regulator driver only calls this API.
- Regulator specific support should be in regulator driver only
  to ease any enhancement/modification for regulators.
- The regulator driver is now registered as mfd sub device and
  all regulator registration is done from single probe call.

Pawel Moll
3ecbf05be1 mfd: Versatile Express config infrastructure
Versatile Express platform has an elaborated configuration system,
consisting of microcontrollers residing on the mother- and
daughterboards known as Motherboard/Daughterboard Configuration
Controller (MCC and DCC). The controllers are responsible for
the platform initialization (reset generation, flash programming,
FPGA bitfiles loading etc.) but also control clock generators,
voltage regulators, gather environmental data like temperature,
power consumption etc. Even the video output switch (FPGA) is
controlled that way.

Those devices are _not_ visible in the main address space and
the usual communication channel uses some kind of a bridge in
the peripheral block sending commands (requests) to the
controllers and receiving responses. It can take up to
500 microseconds for a transaction to be completed, therefore
it is important to provide a non-blocking interface to it.

This patch adds an abstraction of this infrastructure. Bridge
drivers can register themselves with the framework. Then,
a driver of a device can request an abstract "function" - the
request will be redirected to a bridge referred by thedd
"arm,vexpress,config-bridge" property of the device tree node.

All MFD device modules are registered by LP8788 MFD core driver.
For sharing information such like the virtual IRQ number,
MFD core driver uses the resource structure.
Then each module can retrieve the specific IRQ number and detect it
in the IRQ thread.

Configurable platform data is handled in each driver module.

The platform driver for the TLL component of the OMAP USB host controller
is implemented. Depending on the TLL hardware revision , the TLL channels
are configured. The USB HS core driver uses this driver through exported
APIs from the TLL platform driver.
usb_tll_enable and usb_tll_disble are the exported APIs of the USB TLL

The MAX8907 is an I2C-based power-management IC containing voltage

* Tom Cherry <tcherry@nvidia.com>
* Prashant Gaikwad <pgaikwad@nvidia.com>
* Dan Willemsen <dwillemsen@nvidia.com>
* Laxman Dewangan <ldewangan@nvidia.com>

During upstreaming, I (swarren):
* Converted to regmap.
* Converted to regmap-irq.
* Allowed probing from device tree.
* Renamed from max8907c->max8907, since the driver covers at least the
  C and B revisions.
* General cleanup.

8f057d7bca gpu/mfd/usb: Fix USB randconfig problems
Fix config warning:

warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies
(USB_SUPPORT && USB_ARCH_HAS_HCD)

and build error:
ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!

by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.

This exposes:

Fix by dropping I2C from the above dependency; logic is that this is not a

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac96: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").

In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).

I left that part of commit 2761a63945 just undone.

eac7a92fd0 pwm: Conflict with legacy PWM API
In order to avoid duplicate symbols with legacy PWM API implementations,
the new PWM framework needs to conflict with any of the existing legacy
implementations. This is done in two ways: for implementations provided
by drivers, a conflict is added to the driver to ensure it will have to
be ported to the PWM subsystem before it can coexist with other PWM
providers. For architecture-specific code, the conflict is added to the
PWM symbol to avoid confusion when a previously picked platform or
machine can no longer be selected because of the PWM subsystem being
included.

mfd: Initial support for Wolfson Arizona platform and WM5102 devices

The Wolfson Arizona platform is used to provide common register
interface to a series of low power audio hub CODECs, starting with the
WM5102. Since the features of these devices work over a range of
subsystems an MFD core driver is provided to instantiate the subdevices
and arbitrate access between them.

As the new regmap wake IRQ functionality is used as part of the driver
it is incorporated as a dependency.

b41511f713 mfd: Add irq domain support for max8997 interrupts
Add irq domain support for max8997 interrupts. The reverse mapping method
used is linear mapping since the sub-drivers of max8997 such as regulator
and charger drivers can use the max8997 irq_domain to get the linux irq
number for max8997 interrupts. All uses of irq_base in platform data and
max8997 driver private data are removed.

c94bb233a9 mfd: Make MFD core code Device Tree and IRQ domain aware
During Device Tree enablement of the ab8500 and db8500-prcmu drivers,
a decision was made to omit registration through the MFD API and use
Device Tree directly. However, because MFD devices have a different
address space and the ab8500 and db8500 both use I2C to communicate,
this causes issues with address translation during execution of
of_platform_populate(). So the solution is to make the MFD core aware
of Device Tree and have it assign the correct node pointers instead.

To make this work the MFD core also needs to be awere of IRQ domains,
as Device Tree insists on IRQ domain compatibility. So, instead of
providing an irq-base via platform code, in the DT case we simply
look up the IRQ domain and map to the correct virtual IRQ.

As the AB8500 is an IRQ controller in its own right, here we provide

to reference any of its IRQs from a platform's Device Tree.

 A significant number of lines get removed here, in particular because
 the ixp2000 and ixp23xx platforms get removed. These have never been
 extremely popular and have fallen into disuse over time with no active
 maintainer taking care of them. The u5500 soc never made it into a
 product, so we are removing it from the ux500 platform.
 
 Many good cleanups also went into the at91 and omap platforms, as has
 been the case for a number of releases.

ac1806572d regulator updates for 3.5
The major thing here is the addition of some helpers to factor code out
 of drivers, making a fair proportion of regulators much more just data
 rather than code which is nice.
 
 - Helpers in the core for regulators using regmap, providing generic
   implementations of the enable and voltage selection operations which
   just need data to describe them in the drivers.
 - Split out voltage mapping and voltage setting, allowing many more
   drivers to take advantage of the infrastructure for selectors.
 - Loads and loads of cleanups from Axel Lin once again, including many
   changes to take advantage of the above new framework features
 - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI TPS65913,
   TI TWL6035 and TI TWL6037.
 
 Some of the registration changes to support the core refactoring caused
 so many conflicts that eventually topic branches were abandoned for this
 release.

Merge tag 'regulator-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "The major thing here is the addition of some helpers to factor code
  out of drivers, making a fair proportion of regulators much more just
  data rather than code which is nice.

  - Helpers in the core for regulators using regmap, providing generic
    implementations of the enable and voltage selection operations which
    just need data to describe them in the drivers.
  - Split out voltage mapping and voltage setting, allowing many more
    drivers to take advantage of the infrastructure for selectors.
  - Loads and loads of cleanups from Axel Lin once again, including many
    changes to take advantage of the above new framework features
  - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI
    TPS65913, TI TWL6035 and TI TWL6037.

  Some of the registration changes to support the core refactoring
  caused so many conflicts that eventually topic branches were abandoned
  for this release."

cd99758ba3 mfd: Convert wm831x to irq_domain
The modern idiom is to use irq_domain to allocate interrupts. This is
useful partly to allow further infrastructure to be based on the domains
and partly because it makes it much easier to allocate virtual interrupts
to devices as we don't need to allocate a contiguous range of interrupt
numbers.

Convert the wm831x driver over to this infrastructure, using a legacy
IRQ mapping if an irq_base is specified in platform data and otherwise
using a linear mapping, always registering the interrupts even if they
won't ever be used. Only boards which need to use the GPIOs as
interrupts should need to use an irq_base.

This means that we can't use the MFD irq_base management since the
unless we're using an explicit irq_base from platform data we can't rely
on a linear mapping of interrupts.  Instead we need to map things via
the irq_domain - provide a conveniencem function wm831x_irq() to save a
small amount of typing when doing so. Looking at this I couldn't clearly
see anything the MFD core could do to make this nicer.

Since we're not supporting device tree yet there's no meaningful
advantage if we don't do this conversion in one, the fact that the
interrupt resources are used for repeated IP blocks makes accessor
functions for the irq_domain more trouble to do than they're worth.

4af8be67fd regmap: Convert regmap_irq to use irq_domain
This gets us up to date with the recommended current kernel infrastructure
and should transparently give us device tree interrupt bindings for any
devices using the framework. If an explicit IRQ mapping is passed in then
a legacy interrupt range is created, otherwise a simple linear mapping is
used. Previously a mapping was mandatory so existing drivers should not
be affected.

A function regmap_irq_get_virq() is provided to allow drivers to map
individual IRQs which should be used in preference to the existing
regmap_irq_chip_get_base() which is only valid if a legacy IRQ range is
provided.

   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again

dc9913a050 mfd: Use regmap for tps65910 register access.
Using regmap apis for accessing the device registers and
using RBTREE caching mechanims for caching registers.

Enabling caching of the registers which is used for voltage
controls. By doing this, the modify_bits operation is faster as
it does not involve the i2c register read from device, just read
from cache. This results faster set voltage operation.

280ad7fda5 mfd: twl-core: Add IRQ_DOMAIN dependency
TWL4030 depends on IRQ_DOMAIN support, so this patch selects it in Kconfig.
It used to be that CONFIG_IRQ_DOMAIN must only be selected by the architecture,
but recent cleanups have fixed it so that it is safe to select from anywhere.

a3364409c4 MFD: ucb1x00: convert to use genirq
Convert the ucb1x00 driver to use genirq's interrupt services, rather
than its own private implementation.  This allows a wider range of
drivers to use the GPIO interrupts (such as the gpio_keys driver)
without being aware of the UCB1x00's private IRQ system.

This prevents the UCB1x00 core driver from being built as a module,
so adjust the configuration to add that restriction.

6252547b8a ARM: omap: fix broken twl-core dependencies and ifdefs
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:

Unable to handle kernel NULL pointer dereference at virtual address 00000000

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.

8959e74399 mfd: Delete ab3550 driver
The AB3550 never passed the prototype stage. Instead it was used
as a precursor to AB5500 for testing basic building blocks used
in that chip, since they had large similarities. Since AB3550 will
not see the light of day in product form and since the prototypes
are no longer used, let's delete the driver and any references to
it.

94be70d4b2 mfd: Break out ab5500 debugfs code
This breaks the debugfs portions of the AB5500 driver into its own
file. Split off a _raw function to access registers since we don't
want to expose a generically named function globally. Move all
required data structures to a shared ab5500-core.h file.

3d5e2cabf1 mfd: ab5500 chip register access
The analog baseband chip ab5500 is a multi functional chip
containing regulators, charging, gpio, USB and accessory detect.
It also contain various multimedia functionalities like digital
encoder and audio codec.
The core driver added with this patch provides register access via
i2c via PRCMU. Event handling implemented as irq_chip will come in
future patches since it depends on PRCMU functionality not yet
implemented.

1f5a371c07 mfd: Add Intel MSIC driver
Add support for Intel MSIC chip found on Intel Medfield platforms. This
chip embeds several subdevices: audio, ADC, GPIO, power button, etc. The
driver creates platform device for each subdevice.

We also provide an MSIC register access API which should replace the more
generic SCU IPC interface currently used. Existing drivers can choose
whether they convert to this new API or stick with the SCU IPC interface.

8a0a8e8e42 mfd: remove CONFIG_MFD_SUPPORT
We currently have two symbols to control compilation the MFD subsystem,
MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required
at all, it only hides the submenu when not set, with the effect that
Kconfig warns about missing dependencies when another driver selects
an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu
back from menuconfig into a plain menu simplifies the Kconfig syntax
for those kinds of users and avoids the surprise when the menu
suddenly appears because another driver was enabled that selects this
symbol.

f19b2823f8 mfd: twl6040: Add initial support
TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.

TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.

This driver is based on TWL4030 and WM8350 MFD drivers.
