Now that the axp20x-regulators driver supports different variants of the
AXP family, we can enable regulator support for AXP22X without the risk
of incorrectly configuring regulators.

Add support for the AXP22x PMIC devices to the existing AXP20x driver.
This includes the AXP221 and AXP223, which are identical except for
the external data bus. Only AXP221 is added for now. AXP223 will be
added after it's Reduced Serial Bus (RSB) interface is supported.
AXP22x defines a new set of registers, power supplies and regulators,
but most of the API is similar to the AXP20x ones.
A new irq chip definition is used, even though the available interrupts
on AXP22x is a subset of those on AXP20x. This is done so the interrupt
numbers match those on the datasheet.
This patch only enables the interrupts, system power-off function, and PEK
sub-device. The regulator driver must first support different variants
before we enable it from the mfd driver.

Pull irq updates from Thomas Gleixner:
"The irq departement delivers:
- plug a potential race related to chained interrupt handlers
- core updates which address the needs of the x86 irqdomain conversion
- new irqchip callback to support affinity settings for VCPUs
- the usual pile of updates to interrupt chip drivers
- a few helper functions to allow further cleanups and
simplifications
I have a largish pile of coccinelle scripted/verified cleanups and
simplifications pending on top of that, but I prefer to send that
towards the end of the merge window when the arch/driver changes have
hit your tree to avoid API change wreckage as far as possible"

Fix broken probe of da9052 regulators, which since commit b3f6c73db732
("mfd: da9052-core: Fix platform-device id collision") use a
non-deterministic platform-device id to retrieve static regulator
information. Fortunately, adequate error handling was in place so probe
would simply fail with an error message.
Update the mfd-cell ids to be zero-based and use those to identify the
cells when probing the regulator devices.

Pull chrome platform updates from Olof Johansson:
"Here's a set of updates to the Chrome OS platform drivers for this
merge window.
Main new things this cycle is:
- Driver changes to expose the lightbar to users. With this, you can
make your own blinkenlights on Chromebook Pixels.
- Changes in the way that the atmel_mxt trackpads are probed. The
laptop driver is trying to be smart and not instantiate the devices
that don't answer to probe. For the trackpad that can come up in
two modes (bootloader or regular), this gets complicated since the
driver already knows how to handle the two modes including the
actual addresses used. So now the laptop driver needs to know more
too, instantiating the regular address even if the bootloader one
is the probe that passed.
- mfd driver improvements by Javier Martines Canillas, and a few
bugfixes from him, kbuild and myself"

The struct cros_ec_command will be used as an ioctl() argument for the
API to control the ChromeOS EC from user-space. So the data structure
has to be 64-bit safe to make it compatible between 32 and 64 avoiding
the need for a compat ioctl interface. Since pointers are self-aligned
to different byte boundaries, use fixed size arrays instead of pointers
for transferring ingoing and outgoing data with the Embedded Controller.
Also, re-arrange struct members by decreasing alignment requirements to
reduce the needing padding size.

The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of
RTC alarms 0 and 1 were inversed between these two devices. So when
rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to
S2MPS11_IRQ_RTCA1, not RTCA0.
Fix this by using consistent RTC alarm interrupt numbers and adding a
BUILD_BUG_ON for future generations.

Since commit 6e3f62f0793e ("mfd: core: Fix platform-device id
generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when
registering mfd-devices.
Unfortunately, some mfd-drivers rely on the old behaviour of generating
platform-device ids by adding the cell id also to the special value of
PLATFORM_DEVID_NONE. The resulting platform ids are not only used to
generate device-unique names, but are also used instead of the cell id
to identify cells when probing subdevices.
These drivers should be updated to use PLATFORM_DEVID_AUTO, which would
also allow more than one device to be registered without resorting to
hacks (see for example wm831x), but lets fix the regression first by
partially reverting the above mentioned commit with respect to
PLATFORM_DEVID_NONE.

In Quark X1000, there's a single PCI device that provides both
an I2C controller and a GPIO controller. This MFD driver will
split the 2 devices for their respective drivers.
This patch is based on Josef Ahmad's initial work for Quark enabling.

Rk808 has a under voltage detect function, when the voltage of buck is
under 85% the target voltage, the buck output will reset. But if the
power load is too heavy, this function maybe err, when current over
4.2A, although the voltage is normal, but RK808 mistakenly think it is
under 85%, and reset the buck. So let's disable this function.

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

Since commit 0b2712585(linux-next.git) this driver uses regmap_irq and so needs
to select REGMAP_IRQ.
This fixes the following compilation errors:
ERROR: "regmap_irq_get_domain" [drivers/mfd/rt5033.ko] undefined!
ERROR: "regmap_add_irq_chip" [drivers/mfd/rt5033.ko] undefined!

The range of registers used by this driver exceeds that available
via SPI with no paging (127), so we have to override the values
from the default config which is set-up for I2C access.
Also change SPI settings to match device's recommended OTP values.

This adds support for the MediaTek MT6397 PMIC. This is a
multifunction device with the following sub modules:
- Regulator
- RTC
- Audio codec
- GPIO
- Clock
It is interfaced to the host controller using SPI interface by a proprietary
hardware called PMIC wrapper or pwrap. MT6397 MFD is a child device of the
pwrap.

To enable/disable ASPM we should find LINK CONTROL register
in PCI config space. All old chip use 0x80 address, but new
chip may use another address, so we using pci_find_capability()
to get LINK CONTROL address.
rtsx_gops.c was removed, we consider to put some common operations
to this file, but the actual thing is, only a group of chips
are in common ops1, and another group of chips in common ops2,
it is hard to decide put which ops into generic ops file.
