869b9eddf0 mfd: intel-m10-bmc: Add PMCI driver
Add the mfd driver for the Platform Management Component Interface
(PMCI) based interface of Intel MAX10 BMC controller.

PMCI is a software-visible interface, connected to card BMC which
provided the basic functionality of read/write BMC register. The access
to the register is done indirectly via a hardware controller/bridge
that handles read/write/clear commands and acknowledgments for the
commands.

Previously, intel-m10-bmc provided sysfs under
/sys/bus/spi/devices/... which is generalized in this change because
not all MAX10 BMC appear under SPI anymore.

603aed8ffd mfd: intel-m10-bmc: Split into core and spi specific parts
Split the common code from intel-m10-bmc driver into intel-m10-bmc-core
and move the SPI bus parts into an interface specific file.

intel-m10-bmc-core becomes the core MFD functions which can support
multiple bus interface like SPI bus.

9a9e1be12c ARM: sa1100: remove unused board files
The Cerf, H3100, Badge4, Hackkit, LART, NanoEngine, PLEB, Shannon and
Simpad machines were all marked as unused as there are no known users
left. Remove all of these, along with references to them in defconfig
files and drivers.

Four machines remain now: Assabet, Collie (Zaurus SL5500), iPAQ H3600
and Jornada 720, each of which had one person still using them, with
Collie also being supported in Qemu.

96836a35ff mfd: Drop obsolete dependencies on COMPILE_TEST
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.

Linus expressed a desire to have intel_soc_pmic_crc.o (INTEL_SOC_PMIC,
for Crystal Cove) be built on an "allmodconfig" build, when
I2C_DESIGNWARE_PLATFORM=m, to enhance build test coverage.

The PMIC driver won't work in this case since it requires
I2C_DESIGNWARE_PLATFORM=y to operate properly, but adding
"|| COMPILE_TEST" does improve the build test coverage.

This is more than just a clean-up. It also fixes a potential issue
seen when SPI BAR is 64-bit. The current code works if and only if
the PCI BAR of the hidden device is inside 4G address space. In case
when firmware decides to go above 4G, we will get a wrong address.

a3c8f906ed platform/x86/intel: Move intel_pmt from MFD to Auxiliary Bus
Intel Platform Monitoring Technology (PMT) support is indicated by presence
of an Intel defined PCIe Designated Vendor Specific Extended Capabilities
(DVSEC) structure with a PMT specific ID. The current MFD implementation
creates child devices for each PMT feature, currently telemetry, watcher,
and crashlog. However DVSEC structures may also be used by Intel to
indicate support for other features. The Out Of Band Management Services
Module (OOBMSM) uses DVSEC to enumerate several features, including PMT.
In order to support them it is necessary to modify the intel_pmt driver to
handle the creation of the child devices more generically. To that end,
modify the driver to create child devices for any VSEC/DVSEC features on
supported devices (indicated by PCI ID).  Additionally, move the
implementation from MFD to the Auxiliary bus.  VSEC/DVSEC features are
really multifunctional PCI devices, not platform devices as MFD was
designed for. Auxiliary bus gives more flexibility by allowing the
definition of custom structures that can be shared between associated
auxiliary devices and the parent device. Also, rename the driver from
intel_pmt to intel_vsec to better reflect the purpose.

This series also removes the current runtime pm support which was not
complete to begin with. None of the current devices require runtime pm.
However the support will be replaced when a device is added that requires
it.

306456c21c mfd: bd70528: Drop BD70528 support
The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.

33d550701b mfd: arizona: Allow building arizona MFD-core as module
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.

0cab0aa149 mfd: Kconfig: ABX500_CORE should depend on ARCH_U8500
The ST-Ericsson ABX500 Mixed Signal IC family chips are only present on
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
code, and thus should not enable this driver by default.

Additionally, the ARCH_SOCFPGA is too generic as SoCFPGA designs come

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
05f4434bc1 ("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

This patch implements the basic functions of the BMC chip for some Intel

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.

  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

694b5a5d31 ARM: SoC changes for v5.8
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.

  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"

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.

25f1ca31e2 platform/x86: intel_pmc_ipc: Convert to MFD
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.

54b34aa0a7 platform/x86: intel_scu_ipc: Split out SCU IPC functionality from the SCU driver
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.

a77fc11156 mfd: Switch the AB8500 GPADC to IIO
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.

8ceb1417f3 mfd: don't select DMA_DECLARE_COHERENT for the sm501 and tc6393xb drivers
Now that these drivers use the usb localmem pool there is no need to
select DMA_DECLARE_COHERENT.

2fa2b980e3 mfd / platform: cros_ec: Rename config to a better name
The cros-ec-dev is a multifunction device that now doesn't implement any
chardev communication interface. MFD_CROS_EC_CHARDEV doesn't look
a good name to describe that device and can cause confusion. Hence
rename it to CROS_EC_DEV.

Now, the ChromeOS EC core driver has nothing related to an MFD device, so
move that driver from the MFD subsystem to the platform/chrome subsystem.

b9a801dfa5 mfd: Add support for Merrifield Basin Cove PMIC
Add an MFD driver for Intel Merrifield Basin Cove PMIC.

Firmware on the platforms which are using Basin Cove PMIC is "smarter"
than on the rest supported by vanilla kernel. It handles first level
of interrupt itself, while others do it on OS level.

The driver is done in the same way as the rest of Intel PMIC MFD drivers
in the kernel to support the initial design. The design allows to use
one driver among few PMICs without knowing implementation details of
the each hardware version or generation.
