X-Powers AXP288 is a customized PMIC for Intel Baytrail-CR platforms. Similar
to AXP202/209, AXP288 comes with USB charger, more LDO and BUCK channels, and
AD converters. It also provides extended status and interrupt reporting
capabilities than the devices currently supported in axp20x.c.
In addition to feature extension, this patch also adds ACPI binding for
enumeration.
This consolidated driver should support more X-Powers' PMICs in both device
tree and ACPI enumerated platforms.

Instead of having users of the ChromeOS EC call the interface-specific
cmd_xfer() callback directly, introduce a central cros_ec_cmd_xfer()
to use instead. This will allow us to put all the locking and retry
logic in one place instead of duplicating it across the different
drivers.

In <https://lkml.org/lkml/2014/6/10/265> pointed out that the 10-bit
flag in the cros_ec_tunnel was useless. It went into a 16-bit flags
field but was defined at (1 << 16).
Since we have no 10-bit i2c devices on the other side of the tunnel on
any known devices this was never a problem. Until we do it makes
sense to remove this code. On the EC side the code to handle this
flag was removed in <https://chromium-review.googlesource.com/204162>.

If an MFD device is backed by ACPI namespace, we should allow subdevice
drivers to access their corresponding ACPI companion devices through normal
means (e.g using ACPI_COMPANION()).
This patch adds such support to the MFD core. If the MFD parent device
does not specify any ACPI _HID/_CID for the child device, the child
device will share the parent ACPI companion device. Otherwise the child
device will be assigned with the corresponding ACPI companion, if found
in the namespace below the parent.

Current code init regmap with &da9052_regmap_config for both da9052-spi and
da9052-i2c drivers. da9052-spi sets the read_flag_mask.
The same setting may be applied for da9052-i2c if da9052-spi driver is loaded
first because they actually use the same regmap_config setting.
Fix this issue by using a local variable for regmap_config in da9052-spi driver,
so the settings in spi driver won't impact the settings in i2c driver.
Also makes da9052_regmap_config const to avoid similar issue.

A couple of nice new features this month, the ability to map regulators
in order to allow voltage control by external coprocessors is something
people have been asking for for a long time.
- Improved support for switch only "regulators", allowing current state
to be read from the parent regulator but no setting.
- Support for obtaining the register access method used to set

Merge tag 'regulator-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"A couple of nice new features this month, the ability to map
regulators in order to allow voltage control by external coprocessors
is something people have been asking for for a long time.
- improved support for switch only "regulators", allowing current
state to be read from the parent regulator but no setting.
- support for obtaining the register access method used to set
voltages, for use in systems which can offload control of this to a
coprocessor (typically for DVFS).

We only request the control interface error IRQ if we set ctrlif_error,
as such we should only free it in that situation. Otherwise we will
attempt to free an IRQ we never requested and get a warning from the IRQ
core.
This patch moves the ctrlif_error variable into the arizona structure
and checks it in all cases we free the control interface error IRQ.

If we receive EC interrupts after the cros_ec driver has probed, but
before the cros_ec_keyb driver has probed, the cros_ec IRQ handler
will not run the cros_ec_keyb notifier and the EC will leave the IRQ
line asserted. The cros_ec IRQ handler then returns IRQ_HANDLED and
the resulting flood of interrupts causes the machine to hang.
Since the EC interrupt is currently only used for the keyboard, move
the setup and handling of the EC interrupt to the cros_ec_keyb driver.

there are a couple of noticable core changes and the usual stream of
cleanups and fixes:
- Move disable of unused regulators later in init so it comes after
deferred probe has iterated making startup smoother.
- Fixes reference counting of the DT nodes for constraints from Charles
Keepax. This has little practical impact since all real users of
the regulator bindings use FDT which doesn't need the reference
counting.
- Lots of cleanups, especially to the Samsung drivers.

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.

commit df73de9b0d ("mfd: syscon: Return -ENOSYS if CONFIG_MFD_SYSCON
is not enabled") introduced fallbacks for APIs, but missed out on adding
the header file. This would work only if linux/err.h is also included
in the source code from where this file is included. It would be better
to include linux/err.h in file to remove possible build errors.
Without this patch, we get following and similar build errors if this
header file is included in some source file and CONFIG_MFD_SYSCON is
not enabled.

The rtc-s5m driver does not support all of S2M and S5M chipsets
supported by main MFD sec-core driver. For such chipsets unsupported by
rtc-s5m, the MFD sec-core driver initialized regmap with default config.
This config in such cases wouldn't work at all.
The main MFD sec-core driver shouldn't initialize regmap for child
drivers which is not used by them and even not valid.
Move the allocation of RTC I2C dummy device and initialization of RTC
regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m
driver will use proper regmap config for supported devices.

- We are finalizing and fixing up the gpiochip irqchip helpers
bringing a helpful irqchip implementation into the gpiolib
core and avoiding duplicate code and, more importantly,
duplicate bug fixes:
- Support for using the helpers with threaded interrupt
handlers as used on sleeping GPIO-irqchips
- Do not set up hardware triggers for edges or levels if
the default IRQ type is IRQ_TYPE_NONE - some drivers
would exploit the fact that you could get default
initialization of the IRQ type from the core at probe()
but if no default type is set up from the helper, we
should not call the driver to configure anything. Wait
until a consumer requests the interrupt instead.
- Make the irqchip helpers put the GPIO irqs into their
own lock class. The GPIO irqchips can often emit
(harmless, but annoying) lockdep warnings about recursions
when they are in fact just cascaded IRQs. By putting
them into their own lock class we help the lockdep core
to keep track of things.
- Switch the tc3589x GPIO expanders to use the irqchip
helpers
- Switch the OMAP GPIO driver to use the irqchip helpers
- Add some documentation for the irqchip helpers
- select IRQ_DOMAIN when using the helpers since some
platforms may not be using this by default and it's a
strict dependency.
- Continued GPIO descriptor refactoring:
- Remove the one instance of gpio_to_desc() from the
device tree code, making the OF GPIO code use GPIO
descriptors only.
- Introduce gpiod_get_optional() and
gpiod_get_optional_index() akin to the similar
regulator functions for cases where the use of GPIO
is optional and not strictly required.
- Make of_get_named_gpiod_flags() private - we do not
want to unnecessarily expose APIs to drivers that
make the gpiolib harder than necessary to maintain
and refactor. Privatize this function.
- Support "-gpio" suffix for the OF GPIO retrieveal path.
We used to look for "foo-gpios" or just "gpios" in device
tree nodes, but it turns out that some drivers with a
single GPIO line will just state "foo-gpio" (singularis).
Sigh. Support this with a fallback looking for it, as
this simplifies driver code and handles it in core code.
- Switch the ACPI GPIO core to fetch GPIOs with the
*_cansleep function variants as the GPIO operation
region handler can sleep, and shall be able to handle
gpiochips that sleep.
- Tons of cleanups and janitorial work from Jingoo Han,
Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe.
Notably Jingoo cut off a ton of pointless OOM messages.
- Incremental development and fixes for various drivers,
nothing really special here.

Merge tag 'gpio-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio into next
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v3.16 series.
There is a lot of action in the GPIO subsystem doing refactorings and
cleanups, almost as many deletions as insertions and minor feature
growth and no new drivers this time. Which is actually pretty nice.
Some GPIO-related stuff will come in through the pin control tree as
well.
Details:
- We are finalizing and fixing up the gpiochip irqchip helpers
bringing a helpful irqchip implementation into the gpiolib core and
avoiding duplicate code and, more importantly, duplicate bug fixes:
* Support for using the helpers with threaded interrupt handlers as
