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

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.

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
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"

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.

driver so the driver will handle both chipsets. Also this patch replaces
