This adds support for the MediaTek MT6358 PMIC. This is a
multifunction device with the following sub modules:
- Regulator
- RTC
- Codec
- Interrupt
It is interfaced to the host controller using SPI interface
by a proprietary hardware called PMIC wrapper or pwrap.
MT6358 MFD is a child device of the pwrap.

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 SCU IPC functionality is usable outside of Intel MID devices. For
example modern Intel CPUs include the same thing but now it is called
PMC (Power Management Controller) instead of SCU. To make the IPC
available for those split the driver into core part (intel_scu_ipc.c)
and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the
former before it goes and creates rest of the SCU devices. The SCU IPC
will also register a new class that gets assigned to the device that is
created under the parent PCI device.
We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU
IPC library and INTEL_SCU_PCI the SCU driver and convert the users
accordingly. While there remove default y from the INTEL_SCU_PCI symbol
as it is already selected by X86_INTEL_MID.

With the device tree property "rockchip,system-power-controller" we
explicitly request to use this PMIC to power off the system. So always
register our poweroff function, even if some other handler (probably
PSCI poweroff) was registered before.
This does tend to reveal a warning on shutdown due to the Rockchip I2C
driver not implementing an atomic transfer method, however since the
write to DEV_OFF takes effect immediately the I2C completion interrupt
is moot anyway, and as the very last thing written to the console it is
only visible to users going out of their way to capture serial output.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

- Improve cop0 counter synchronization behaviour whilst onlining CPUs
by running with interrupts disabled.
- Better match FPU behaviour when emulating multiply-accumulate
instructions on pre-r6 systems that implement IEEE754-2008 style
MACs.
- Loongson64 kernels now build using the MIPS64r2 ISA, allowing them
to take advantage of instructions introduced by r2.
- Support for the Ingenic X1000 SoC & the really nice little CU Neo
development board that's using it.
- Support for WMAC on GARDENA Smart Gateway devices.
- Lots of cleanup & refactoring of SGI IP27 (Origin 2*) support in
preparation for introducing IP35 (Origin 3*) support.
- Various Kconfig & Makefile cleanups"

There are a lot of similar global registers being used across multiple SoCs
from Unisoc. But most of these registers are assigned with different offset
for different SoCs. It is hard to handle all of them in an all-in-one
kernel image.
Add a helper function to get regmap with arguments where we could put some
extra information such as the offset value.

Add the cros-usbpd-notify driver as a subdevice on platforms that
support the EC_FEATURE_USB_PD EC feature flag and don't have the
ACPI PD notification device defined.
This driver allows other cros-ec devices to receive PD event
notifications from the Chrome OS Embedded Controller (EC) via a
notification chain.

The watchdog driver compatible is "dlg,da9062-watchdog" and not
"dlg,da9062-wdt". Therefore the mfd-core can't populate the of_node and
fwnode. As result the watchdog driver can't parse the devicetree.

Both manual and power on resets have a brief period where the chip will
not be accessible immediately afterwards. Extend the time allowed for
this from a minimum of 1mS to 2mS based on newer evaluation of the
hardware and ensure this reset happens in all reset conditions. Whilst
making the change also remove the redundant NULL checks in the reset
functions as the GPIO functions already check for this.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
name.
"SAMSUNG" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).
