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.

MFD support for DA9061 is provided as part of the DA9062 device driver.
The registers header file adds two new chip variant IDs defined in DA9061
and DA9062 hardware. The core header file adds new software enumerations
for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration
for distinguishing between DA9061/62 devices in software.
The core source code adds a new .compatible of_device_id entry. This is
extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The
.data entry now holds a reference to the enumerated device type.
A new regmap_irq_chip model is added for DA9061 and this supports the new
list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the
new sub system components for DA9061. Support is added for a new DA9061
regmap_config which lists the correct readable, writable and volatile
ranges for this chip.
The probe function uses the device tree compatible string to switch on the
da9062_compatible_types and configure the correct mfd cells, irq chip and
regmap config.
Kconfig is updated to reflect support for DA9061 and DA9062 PMICs.

These new helpers + macro definitions are meant to replace the old ones
which are unpractical to use.
Note that the macros and function prefixes have been intentionally
changed to ATMEL_[H]SMC_XX and atmel_[h]smc_ to reflect the fact that
this IP is also embedded in avr32 SoCs (and not only in at91 ones).

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.

This hardware block could at used at same time for PWM generation
and IIO timers.
PWM and IIO timer configuration are mixed in the same registers
so we need a multi fonction driver to be able to share those registers.
version 7:
- rebase on v4.10-rc2
version 6:
- rename files to stm32-timers
- rename functions to stm32_timers_xxx
version 5:
- fix Lee comments about detect function
- add missing dependency on REGMAP_MMIO
version 4:
- add a function to detect Auto Reload Register (ARR) size
- rename the structure shared with other drivers
version 2:
- rename driver "stm32-gptimer" to be align with SoC documentation
- only keep one compatible
- use of_platform_populate() instead of devm_mfd_add_devices()

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.)

The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config MFD_AS3722
drivers/mfd/Kconfig: bool "ams AS3722 Power Management IC"
...meaning that it currently is not being built as a module by anyone.
In response to an earlier patch set suggesting removal of the unused
modular code, Laxman suggested that this driver be instead moved to
tristate.
We do that here, and confirm it can build and modpost as a tristate.
However there remains to be runtime testing in order to ensure this
change is 100% functional for "=m".

The MFD_VEXPRESS_SYSREG driver selects CLKSRC_MMIO, which in turn
conflicts with ARCH_USES_GETTIMEOFFSET, causing a harmless Kconfig
warning when it is set:
warning: (ARCH_MVEBU && ARCH_DIGICOLOR && ARCH_GEMINI && ARCH_KEYSTONE && ARCH_MOXART && ARCH_MXS && PLAT_SPEAR && ARCH_SUNXI && ARCH_TEGRA && ARCH_U300 && PLAT_ORION && ARCH_CLPS711X && ARCH_EP93XX && ARCH_NETX && ARCH_IXP4XX && ARCH_KS8695 && ARCH_W90X900 && ARCH_PXA && ARCH_SA1100 && ARCH_OMAP1 && ARCH_BCM_IPROC && ARCH_INTEGRATOR_AP && ARCH_OMAP2PLUS && MFD_VEXPRESS_SYSREG) selects CLKSRC_MMIO which has unmet direct dependencies (!ARCH_USES_GETTIMEOFFSET)
This was apparently hidden by the fact that no ARM platform that
still sets ARCH_USES_GETTIMEOFFSET has gpiolib support, and we
already have a dependency on GPIOLIB that I added a while ago.
However, after 296ad4acb8ef ("gpio: remove deps on
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"), any platform can enable
CONFIG_GPIOLIB, and that lets us enable MFD_VEXPRESS_SYSREG
as well.
This adds an explicit dependency on !ARCH_USES_GETTIMEOFFSET
to guarantee that we can enable the CLKSRC_MMIO driver without
getting warnings.

These drivers can be built as module, so make them depend on I2C rather
than I2C=y.

The AXP223 is a new PMIC commonly paired with Allwinner A23/A33 SoCs.
It is functionally identical to AXP221; only the regulator default
voltage/status and the external host interface are different.

The axp20x driver assumes the device is i2c based. This is not the
case with later chips, which use a proprietary 2 wire serial bus
by Allwinner called "Reduced Serial Bus".
This patch follows the example of mfd/wm831x and splits it into
an interface independent core, and an i2c specific glue layer.
MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate
symbols, allowing the driver to be built as modules.
Whitespace and other style errors in the moved i2c specific code
have been fixed. Included but unused header files are removed as
well.

This is the core driver for imx25 touchscreen/adc driver. The module
has one shared ADC and two different conversion queues which use the
ADC. The two queues are identical. Both can be used for general purpose
ADC but one is meant to be used for touchscreens.
This driver is the core which manages the central components and
registers of the TSC/ADC unit. It manages the IRQs and forwards them to
the correct components.

Allow support for the DA9063 PMIC to be modular, cfr. DA9062, which
allows to decrease size of multi-platform kernels (e.g.
multi_v7_defconfig).

This patch adds the regmap configuration tables and
core MFD handling for the CS47L24 and WM1831 codecs.
Note that compared to the other Arizona codecs, these devices
do not have an LDO1 or micsupp regulators, extcon driver, or
the DCVDD isolation control.
