The regmap devicetree binding documentation states that a native-endian
property should be supported as well as big-endian & little-endian,
however syscon in its duplication of the parsing of these properties
omits support for native-endian. Fix this by setting
REGMAP_ENDIAN_NATIVE when a native-endian property is found.

If the driver is built as a module, autoload won't work because the module

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.)

Subsystem improvements:
- Do away with the last users of the obsolete Kconfig options
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
always sounded like an item on a wishlist to Santa Claus to
me). We can now select GPIOLIB and be done with it, for all
archs. After some struggle it even work on UM. Not that it has
GPIO, but if it wants to, it can select the library.
- Continued efforts to make drivers properly either tristate or
bool.
- Introduce a warning for drivers assigning default triggers to
their irqchip lines when probed from device tree, so we find and
fix these ambigous drivers. It is agreed that in the OF config
path, the device tree defines trigger characteristics.
- The same warning, mutatis mutandis, for ACPI-probed GPIO
irqchips.
- We introduce the ability to mark certain IRQ lines as "unusable"
as they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is
put to good use in the STMPE driver and also in the Cherryview
pin control driver.
- A new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM
with allyesconfig or allmodconfig it exploded in their face.
- Move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so
now eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- New driver for the Aspeed GPIO front-end companion to the
pin controller merged through the pin control tree.
- New driver for the LP873x PMIC GPIO portions.
- New driver for Technologic Systems' I2C FPGA GPIO such as
TS4900, TS-7970, TS-7990 and TS-4100.
- New driver for the Broadcom BCM63xx series including BCM6338

- New driver for the Intel WhiskeyCove PMIC GPIO.
- New driver for the Allwinner AXP209 PMIC GPIO portions.
- New driver for Diamond Systems 48 line GPIO-MM, another of
these port-mapped I/O expansion cards.
- Support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- The STMPE driver now supports rising/falling edge detection
properly for IRQs.
- The PCA954x will now fetch and enable its VCC regulator properly.
- Major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- Switch the IOP driver to use the generic MMIO GPIO library.
- Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver

"This is an extremely quiet release for the regulator API, we've got a
small set of bug fixes and minor feature enhancements for drivers plus
a couple of more visible changes:
- add support for ramp times in regulators that don't use selectors.
- new driver for LTC3676"

The Arizona CODECs will generally function correctly without a reset line
although it is strongly advised to have one, as such we do allow the system
to boot if the reset gpio is missing or incorrectly specified. However
we should fail probe if we get a probe deferral request, this patch adds
handling for this case.

This function is only used in a single place and no new users will be
added as all the devices other required GPIOs are already handled. As
such just merge the code back into the calling function.

The McPDM in OMAP4/5 is using the pdmclk from twl6040 as functional clock.
The twl6040-pdmclk driver provides a clock which can be used to make sure
that the pdmclk is active when the McPDM is in use.

Due to the lack of parity in the way array fields have been named/
numbered, a mistake was made where more debug fields were declared
than actually existed. In doing so, 2 fields were added, which
although unclear, were already declared in the array. The result
was that the latter declarations trashed the former ones.
This patch places the array back in the correct order and removes
the offending NULL entries.
While we're at it, let's ensure this doesn't happen again by naming
each field properly and add a new *_LAST define to describe how
many fields there should be.

The tps65217 gained a new warning when building with W=1:
drivers/mfd/tps65217.c:85:1: error: 'inline' is not at beginning of declaration [-Werror=old-style-declaration]

readl_poll_timeout() calls usleep_range(), but
regmap_atmel_hlcdc_reg_write() is called in atomic context (regmap
spinlock held).
Replace the readl_poll_timeout() call by readl_poll_timeout_atomic().

The newly added exynos lpass driver produces a build warning when
CONFIG_PM is disabled since the only callers of exynos_lpass_disable
are under an #ifdef:
drivers/mfd/exynos-lpass.c:93:13: error: 'exynos_lpass_disable' defined but not used [-Werror=unused-function]
static void exynos_lpass_disable(struct exynos_lpass *lpass)
This removes the #ifdef and replaces it with __maybe_unused annotations
so the compiler can leave out the unused code silently with less
room for mistakes.

Default I2C device properties for Intel Broxton, especially SDA hold time
may not be enough on Intel Apollo Lake. These properties are used in case
we don't get timing parameters from ACPI.
The default SDA hold time for Broxton may fail with arbitration lost errors
on Apollo Lake:
i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration
Fix this by using different default device properties on Apollo Lake than
Broxton.

The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config TWL4030_CORE
drivers/mfd/Kconfig: bool "TI TWL4030/TWL5030/TWL6030/TPS659x0 Support"
...meaning that it currently is not being built as a module by anyone.
Lets remove what modular code that we can, so that when reading the
driver there is less doubt that it is builtin-only. Note that we can't
remove the twl_remove() itself ; it is still used by the probe unwind
routine. So we leave it linked into the .remove as well, even though
it will most likely never be called via that path from an unbind.
Since module_i2c_driver() uses the same init level priority as
builtin_i2c_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

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".

changes. Mask and interrupt bits are shared within one register, which
prevents us to use regmap_irq implementation. New irq_domain is created in
order to add interrupt handling for each tps65217's subsystem. IRQ
