Prepare for adding support for S2MPS14 RTC device to the rtc-s5m driver: 1. Rename SEC* symbols to S5M. 2. Add S5M prefix to some of defines which are different between S5M876X and S2MPS14.

The bulk of the changes for this release are a few new drivers however
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.
- Support for Linear Technologies LTC3589, Texas Instruments TPS658640
and X-Powers AXP20x.

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.

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.

The MAX77836 charger and safeout regulators are almost identical to MAX14577. The registers layout is the same, except values for charger's current.

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.
