There is no reason why the arizona core,irq and codec model specific
regmap bits cannot be build as a module. All they do is export symbols
which are used by the arizona-spi/i2c and arizona-codec modules, which
themselves can be built as module.
Change the Kconfig and Makefile arizona bits so that the arizona MFD-core
can be built as a module.
This is especially useful on x86 platforms with a WM5102 codec, this
allows the arizona MFD driver necessary for the WM5102 codec to be
enabled in generic distro-kernels without growing the base kernel-image
size.
Note this also adds an explicit "depends on MFD_ARIZONA" to all the
arizona codec Kconfig options. The codec drivers use functions from mfd
arizona-core. These new depends are necessary to disallow the codec
drivers being builtin when the arizona-core is build as a module,
otherwise we end up with missing symbol errors when building vmlinuz.

ST-Ericsson U8500 Series platforms. Hence add a dependency on
ARCH_U8500, to prevent asking the user about this driver when
configuring a kernel without U8500 support.
Also, merely enabling CONFIG_COMPILE_TEST should not enable additional

Simplify 32-bit and 64-bit Intel SoCFPGA Kconfig options by having only
one for both of them. This the common practice for other platforms.
Additionally, the ARCH_SOCFPGA is too generic as SoCFPGA designs come
from multiple vendors.

both 32-bit and 64-bit Intel SoCFPGA, even though it is used only for
32-bit.

Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.
There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. Commit
05f4434bc130 ("ASoC: Intel: remove mfld_machine") is also in align
with this theory.
Due to above and to reduce a burden of supporting outdated drivers,
remove the support for outdated platforms completely.

Instead of also adding the newly supported devices to the Kconfig

Intel Platform Monitoring Technology (PMT) is an architecture for
enumerating and accessing hardware monitoring facilities. PMT supports
multiple types of monitoring capabilities. This driver creates platform
devices for each type so that they may be managed by capability specific
drivers (to be introduced). Capabilities are discovered using PCIe DVSEC
ids. Support is included for the 3 current capability types, Telemetry,
Watcher, and Crashlog. The features are available on new Intel platforms
starting from Tiger Lake for which support is added. This patch adds
support for Tiger Lake (TGL), Alder Lake (ADL), and Out-of-Band Management
Services Module (OOBMSM).
Also add a quirk mechanism for several early hardware differences and bugs.
For Tiger Lake and Alder Lake, do not support Watcher and Crashlog
capabilities since they will not be compatible with future product. Also,
fix use a quirk to fix the discovery table offset.

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 MFD driver has no user. The keypad driver of this device never made
it into the kernel. Therefore, this driver is useless. Remove it.

This Microcontroller is present on the Khadas VIM1, VIM2, VIM3 and Edge
boards.
It has multiple boot control features like password check, power-on
options, power-off control and system FAN control on recent boards.
This implements a very basic MFD driver with the fan control and User
NVMEM cells.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Pull ARM SoC updates from Arnd Bergmann:
"One new platform gets added, the Realtek RTD1195, which is an older
Cortex-a7 based relative of the RTD12xx chips that are already
supported in arch/arm64. The platform may also be extended to support
running 32-bit kernels on those 64-bit chips for memory-constrained
machines.
In the Renesas shmobile platform, we gain support for "RZ/G1H" or
R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores,
originally released in 2016 as one of the last high-end 32-bit
designs.
There is ongoing cleanup for the integrator, tegra, imx, and omap2
platforms, with integrator getting very close to the goal of having
zero code in arch/arm/, and omap2 moving more of the chip specifics
from old board code into device tree files.
The Versatile Express platform is made more modular, with built-in
drivers now becoming loadable modules. This is part of a greater
effort for the Android OS to have a common kernel binary for all
platforms and any platform specific code in loadable modules.
The PXA platform drops support for Compulab's pxa2xx boards that had
rather unusual flash and PCI drivers but no known users remaining. All
device drivers specific to those boards can now get removed as well.
Across platforms, there is ongoing cleanup, with Geert and Rob
revisiting some a lot of Kconfig options"

Enable building the vexpress-sysreg driver as a module.
As deferred probe between the vexpress components works now, we don't
need to create struct devices early with of_platform_device_create().

Nothing in the VExpress sysregs nor the MFD child drivers use
CONFIG_CLKSRC_MMIO. There's the 24MHz counter, but that's handled by
drivers/clocksource/timer-versatile.c which doesn't use
CONFIG_CLKSRC_MMIO either. So let's just drop CONFIG_CLKSRC_MMIO.
As the !ARCH_USES_GETTIMEOFFSET dependency was added for
CONFIG_CLKSRC_MMIO, that can be dropped, too.

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.
