This patch adds the MFD driver for Dollar Cove (TI version) PMIC with
ACPI INT33F5 that is found on some Intel Cherry Trail devices.
The driver is based on the original work by Intel, found at:
https://github.com/01org/ProductionKernelQuilts
This is a minimal version for adding the basic resources. Currently,
only ACPI PMIC opregion and the external power-button are used.

The WM9705, WM9712 and WM9713 are highly integrated codecs, with an
audio codec, DAC and ADC, GPIO unit and a touchscreen interface.
Historically the support was spread across drivers/input/touchscreen and
sound/soc/codecs. The sharing was done through ac97 bus sharing. This
model will not withstand the new AC97 bus model, where codecs are
discovered on runtime.

Add mfd driver for Intel CHT Whiskey Cove PMIC, based on various non
upstreamed CHT Whiskey Cove PMIC patches.
This is a somewhat minimal version which adds irqchip support and cells
for: ACPI PMIC opregion support, the i2c-controller driving the external
charger irc and the pwrsrc/extcon block.
Further cells can be added in the future if/when drivers are upstreamed
for them.
[The above patch caused a build error on some archetectures]
From: Arnd Bergmann <arnd@arndb.de>
I ran into a build error on ARM with a platform that has a non-standard
clk implementation:
drivers/clk/clk.o: In function `clk_disable':
clk.c:(.text.clk_disable+0x0): multiple definition of `clk_disable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_disable+0x0): first defined here
drivers/clk/clk.o: In function `clk_enable':
clk.c:(.text.clk_enable+0x0): multiple definition of `clk_enable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_enable+0x0): first defined here
The problem is a device driver that uses 'select COMMON_CLK', which is
generally a bad idea: selecting a subsystem should only be done from
a platform, otherwise we run into circular dependencies. The same driver
also selects 'GPIOLIB' and 'I2C', which has a similar effect.
This turns all three into 'depends on', as it should be.
Finally, we can limit the build to x86, unless we are compile testing.

Crystal Cove and Whiskey Cove are two different PMICs which are
installed on Intel Atom SoC based platforms.
Moreover there are two independent drivers that by some reason were
supposed (*) to get into one kernel module.
Fix the mess by clarifying Kconfig option for Crystal Cove and split
Whiskey Cove out of it.
(*) It looks like the configuration was never tested with
INTEL_SOC_PMIC=n. The line in Makefile is actually wrong.

TI LMU (Lighting Management Unit) driver supports lighting devices below.
LM3532, LM3631, LM3632, LM3633, LM3695 and LM3697.
LMU devices have common features.
- I2C interface for accessing device registers
- Hardware enable pin control
- Backlight brightness control
- Notifier for hardware fault monitoring
- Regulators for LCD display bias
It contains fault monitor, backlight, LED and regulator driver.
LMU fault monitor
-----------------
LM3633 and LM3697 provide hardware monitoring feature.
It enables open or short circuit detection.
After monitoring is done, each device should be re-initialized.
Notifier is used for this case.
Separate patch for 'ti-lmu-fault-monitor' will be sent later.
Backlight
---------
It's handled by TI LMU backlight consolidated driver and
chip dependent data. Separate patchset will be sent later.
LED indicator
-------------
LM3633 has 6 indicator LEDs. Programmable dimming pattern is also
supported. Separate patch for 'leds-lm3633' will be sent later.
Regulator
---------
LM3631 has 5 regulators for the display bias.
LM3632 supports 3 regulators. One consolidated driver enables it.
The lm363x regulator driver is already upstreamed.

Many Motorola phones like droid 4 are using a custom PMIC called CPCAP
or 6556002. We can support it's core features quite easily with regmap_spi
and regmap_irq.
The children of cpcap, such as regulators, ADC and USB, can be just regular
device drivers and defined in the dts file. They get probed as we call
of_platform_populate() at the end of our probe, and then the children
can just call dev_get_regmap(dev.parent, NULL) to get the regmap.

The Kconfig and file naming for the PM8xxx driver is totally
confusing:
- Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel
users depending on or selecting either at random.
- A driver file named pm8921-core.c even if it is indeed
used by the whole PM8xxx family of chips.
- An irqchip named pm8xxx since it was (I guess) realized that
the driver was generic for all pm8xxx PMICs.
As I may want to add support for PM8901 this is starting to get
really messy. Fix this situation by:
- Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX
and convert all users, including LEDs Kconfig and ARM defconfigs
for qcom and multi_v7 to use that single symbol.
- Renaming the driver to qcom-pm8xxx.c to fit along the two
other qcom* prefixed drivers.
- Rename functions withing the driver from 8921 to 8xxx to
indicate it is generic.
- Just drop the =m config from the pxa_defconfig, I have no clue
why it is even there, it is not a Qualcomm platform. (Possibly
older Kconfig noise from saveconfig.)

This driver supports the new Atmel Flexcom. The Flexcom is a wrapper which
integrates one SPI controller, one I2C controller and one USART. Only one
function can be enabled at a time. This driver selects the function once
for all, when the Flexcom is probed, according to the value of the new

This patch implements the USB part of the Diolan USB-I2C/SPI/GPIO
Master Adapter DLN-2. Details about the device can be found here:
https://www.diolan.com/i2c/i2c_interface.html.
Information about the USB protocol can be found in the Programmer's
Reference Manual [1], see section 1.7.
Because the hardware has a single transmit endpoint and a single
receive endpoint the communication between the various DLN2 drivers
and the hardware will be muxed/demuxed by this driver.
Each DLN2 module will be identified by the handle field within the DLN2
message header. If a DLN2 module issues multiple commands in parallel
they will be identified by the echo counter field in the message header.
The DLN2 modules can use the dln2_transfer() function to issue a
command and wait for its response. They can also register a callback
that is going to be called when a specific event id is generated by
the device (e.g. GPIO interrupts). The device uses handle 0 for
sending events.

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)

Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).
Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:
* a rework (and move to drivers/bus directory, as suggested
by Samuel and Arnd) of the config bus core, which is much
simpler now and uses device model infrastructure (class)
to keep track of the bridges; non-DT case (soon to be
retired anyway) is simply covered by a special device
registration function
* the new config-bus driver also takes over device population,
so there is no need for special matching table for
of_platform_populate nor "simple-bus" hack in the arm64
model dtsi file (relevant bindings documentation has
been updated); this allows all the vexpress devices
fit into normal device model, making it possible
to remove plenty of early inits and other hacks in
the near future
* adaptation of the syscfg bridge implementation in the
sysreg driver, again making it much simpler; there is
a special case of the "energy" function spanning two
registers, where they should be both defined in the tree
now, but backward compatibility is maintained in the code
* modification of the relevant drivers:
* hwmon - just a straight-forward API change
* power/reset driver - API change
* regulator - API change plus error handling
simplification
* osc clock driver - this one required larger rework
in order to turn in into a standard platform driver

Merge tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFS update from Samuel Ortiz:
"This is the MFD patch set for the 3.8 merge window.
We have several new drivers, most of the time coming with their sub
devices drivers:
- Austria Microsystem's AS3711
- 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."
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.

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.

This is a platform driver for Versatile Express' "system
register" block. It's a random collection of registers providing
the following functionality:
- low level platform functions like board ID access; in order to
use those, the driver must be initialized early, either statically
or based on the DT
- config bus bridge via "system control" interface; as the response
from the controller does not generate interrupt (yet), the status
register is periodically polled using a timer
- pseudo GPIO lines providing MMC card status and Flash WP#
signal control
- LED interface for a set of 8 LEDs on the motherboard, with
"heartbeat", "mmc0" and "cpu0" to "cpu5" as default triggers
Signed-off-by: Pawel Moll <pawel.moll@arm.com>
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.

These cleanups are basically all over the place. The idea is to collect
changes with minimal impact but large number of changes so we can avoid
them from distracting in the diffstat in the other series.
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.

ab8500-i2c is used as core code to register the ab8500 device.
After allocating ab8500 memory, it immediately calls into
ab8500-core where the real initialisation takes place. This
patch moves all core registration and memory allocation into
the true ab8500-core file and removes ab8500-i2c completely.

Describe the register map to the regmap core so that we can use its
diagnostic features and cache support. This is split out from the patch
using it due to the size so that the actual code change is a bit clearer.
As the various devices are supersets of each other the access maps are
built up by layering the functions on top of each other, though the
interface for specifying the register defaults isn't currently amenable
to this.

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
