This patch implements the basic functions of the BMC chip for some Intel
FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the
Intel MAX 10 CPLD.
This BMC chip is connected to the FPGA by a SPI bus. To provide direct
register access from the FPGA, the "SPI slave to Avalon Master Bridge"
(spi-avmm) IP is integrated in the chip. It converts encoded streams of
bytes from the host to the internal register read/write on the Avalon
bus. So This driver uses the regmap-spi-avmm for register accessing.

This driver provides access to the EC RAM of said embedded controller
attached to the I2C bus as well as optionally supporting its slightly weird
power-off/restart protocol.
A particular implementation of the EC firmware can be identified by a
model byte. If this driver identifies the Dell Ariel platform, it
registers the appropriate cells.

There are I2C devices which contain several different functions but
doesn't require any special access functions. For these kind of drivers
an I2C regmap should be enough.
Create an I2C driver which creates an I2C regmap and enumerates its
children. If a device wants to use this as its MFD core driver, it has
to add an individual compatible string. It may provide its own regmap
configuration.
Subdevices can use dev_get_regmap() on the parent to get their regmap
instance.

This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.
MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.
The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

The AB8500 GPADC driver is indeed a "general purpose ADC" driver,
and while the IIO subsystem did not exist when the driver was
first merged, it is never too late to clean things up and move it
to the right place.
Nowadays IIO provides the right abstractions and interfaces to
do generic ADC work in the kernel.
We have to cut a bunch of debugfs luggage to make this transition
swift, but all these files to is read out the raw values of the
ADC and the IIO subsystem already has a standard sysfs ABI for
doing exactly this: no debugfs is needed.

As the Lochnagar is a fairly complex device this MFD driver

Merge branches 'ib-mfd-4.19', 'ib-mfd-gpio-pinctrl-4.19', 'ib-mfd-i915-media-platform-4.19' and 'ib-mfd-regulator-4.19', tag 'ib-platform-chrome-mfd-move-cros-ec-transport-for-4.19' into ibs-for-mfd-merged
Immutable branch (mfd, chrome) due for the v4.19 window
Immutable Branch which moves the cros_ec_i2c and cros_ec_spi
transport drivers from mfd to platform/chrome. Changes in arm are a simple
rename in defconfigs. Change in input is a rename in help text.
There are some cros-ec transport drivers (I2C, SPI) living in MFD, while
others (LPC) living in drivers/platform. The transport drivers are more
platform specific. So, move the I2C and SPI transport drivers to the
platform/chrome directory. The patch also removes the MFD_ prefix of
their Kconfig symbols.

This adds the generic core support for Cirrus Logic "Madera" class codecs.
These are complex audio codec SoCs with a variety of digital and analogue
I/O, onboard audio processing and DSPs, and other features.
These codecs are all based off a common set of hardware IP so can be
supported by a core of common code (with a few minor device-to-device
variations).

This reverts commit e04653a9dc.
It is no longer needed to install Chrome EC GPE handler to have
GPE enabled in suspend to idle path. It is found that with this
handler installed, EC wake up doesn't work because default EC
event handler that can wake up system is not getting called.

Add a driver for RAVE Supervisory Processor, an MCU implementing
various bits of housekeeping functionality (watchdoging, backlight
control, LED control, etc) on RAVE family of products by Zodiac
Inflight Innovations.
This driver implementes core MFD/serdev device as well as
communication subroutines necessary for commanding the device.

The cros_ec_dev module is responsible for registering the MFD devices
attached to the ChromeOS EC. This patch moves this module to drivers/mfd
so calls to mfd_add_devices() are not done from outside the MFD subtree
anymore.

Because Realtek card reader drivers are pcie and usb drivers,
and they bridge mmc subsystem and memstick subsystem, they are
not mfd drivers. Greg and Lee Jones had a discussion about
where to put the drivers, the result is that misc is a good
place for them, so I move all files to misc. If I don't move
them to a right place, I can't add any patch for this driver.
