The P2SB library is used for various drivers, including server
platforms. That's why the dependency on X86_PLATFORM_DEVICES
seems superfluous.

Currently, AMD supported platform drivers are grouped under generic "x86"
folder structure. Move the current drivers (amd-pmc and amd_hsmp) to a
separate directory. This would also mean the newer driver submissions to
pdx86 subsystem in the future will also land in AMD specific directory.

The def_bool y PMC_ATOM Kconfig option provides a couple of symbols used
by the code enabled by the X86_INTEL_LPSS option and it registers some
clocks. These clocks are only registered on Bay Trail, Cherry Trail and
Brasswell Intel SoCs and kernels targeting these SoCs must always have
the X86_INTEL_LPSS option enabled otherwise many things will not work.
Building the PMC_ATOM code on kernels which are not targeting the
mentioned SoCs and which do not have the X86_INTEL_LPSS enabled is
not useful.
This means that we can simplify things by replacing the PMC_ATOM Kconfig
option in Makefiles with X86_INTEL_LPSS and then drop the option.

Recent Fam19h EPYC server line of processors from AMD support system
management functionality via HSMP (Host System Management Port) interface.
The Host System Management Port (HSMP) is an interface to provide
OS-level software with access to system management functions via a
set of mailbox registers.
More details on the interface can be found in chapter
"7 Host System Management Port (HSMP)" of the following PPR
https://www.amd.com/system/files/TechDocs/55898_B1_pub_0.50.zip
This patch adds new amd_hsmp module under the drivers/platforms/x86/
which creates miscdevice with an IOCTL interface to the user space.
/dev/hsmp is for running the hsmp mailbox commands.

Add a driver for the keyboard, touchpad and USB port of
the keyboard dock for the Asus TF103C 2-in-1 tablet.
This keyboard dock has its own I2C attached embedded controller
and the keyboard and touchpad are also connected over I2C,
instead of using the usual USB connection. This means that the
keyboard dock requires this special driver to function.

x86 tablets which ship with Android as (part of) the factory image
typically have various problems with their DSDTs. The factory kernels
shipped on these devices typically have device addresses and GPIOs
hardcoded in the kernel, rather then specified in their DSDT.
With the DSDT containing a random collection of devices which may or
may not actually be present as well as missing devices which are
actually present.
This driver, which loads only on affected models based on DMI matching,
adds DMI based instantiating of kernel devices for devices which are
missing from the DSDT, fixing e.g. battery monitoring, touchpads and/or
accelerometers not working.
Note the Kconfig help text also refers to "various fixes" ATM there are
no such fixes, but there are also known cases where entries are present
in the DSDT but they contain bugs, such as missing/wrong GPIOs. The plan
is to also add fixes for things like this here in the future.
This is the least ugly option to get these devices to fully work and to
do so without adding any extra code to the main kernel image (vmlinuz)
when built as a module.

This mainly implements detection of these devices and will allow
secondary drivers to work on such machines.
The identification is DMI-based with a vendor specific way to tell them
apart in a reliable way.
Drivers for LEDs and Watchdogs will follow to make use of that platform
detection.
There is also some code to allow secondary drivers to find GPIO memory,
that needs to be in place because the pinctrl drivers do not come up.

While introduction of this menu brings a nice view in the configuration tools,
it brought more issues than solves, i.e. it prevents to locate files in the
intel/ subfolder without touching non-related Kconfig dependencies elsewhere.
Drop X86_PLATFORM_DRIVERS_INTEL altogether.
Note, on x86 it's enabled by default and it's quite unlikely anybody wants to
disable all of the modules in this submenu.

Add driver to handle WMI events, control the keyboard backlight and
bind/unbind the keyboard-touch / digitizer driver so that only one
is active at a time.
It may seem a bit weird to handle the toggling of the modes in the
kernel, but the hw actually expects only 1 device to be active
at a time.
Changes by Hans de Goede:
- Whole bunch of cleanups
- Make the kernel do the driver bind/unbind itself instead of
sending events to userspace and requiring a special userspace
daemon to deal with this

Barco P50 board
Add a driver providing access to the GPIOs for the identify button and led
present on Barco P50 board, based on the pcengines-apuv2.c driver.
There is unfortunately no suitable ACPI entry for the EC communication
interface, so instead bind to boards with "P50" as their DMI product family
and hard code the I/O port number (0x299).
The driver also hooks up the leds-gpio and gpio-keys-polled drivers to the
GPIOs, so they are finally exposed as:
LED:
/sys/class/leds/identify
Button: (/proc/bus/input/devices)

A number of upcoming notebook computer designs drive the internal
display panel's backlight PWM through the Embedded Controller (EC).
This EC-based backlight control can be plumbed through to an ACPI
"WMAA" method interface, which in turn can be wrapped by WMI with
the GUID handle 603E9613-EF25-4338-A3D0-C46177516DB7.
Add a new driver, aliased to the WMAA WMI GUID, to expose a sysfs
backlight class driver to control backlight levels on systems with
EC-driven backlights.

ACPI devices with _HID INT3472 are currently matched to the tps68470
driver, however this does not cover all situations in which that _HID
occurs. We've encountered three possibilities:
1. On Chrome OS devices, an ACPI device with _HID INT3472 (representing
a physical TPS68470 device) that requires a GPIO and OpRegion driver
2. On devices designed for Windows, an ACPI device with _HID INT3472
(again representing a physical TPS68470 device) which requires GPIO,
Clock and Regulator drivers.
3. On other devices designed for Windows, an ACPI device with _HID
INT3472 which does **not** represent a physical TPS68470, and is instead
used as a dummy device to group some system GPIO lines which are meant
to be consumed by the sensor that is dependent on this entry.
This commit adds a new module, registering a platform driver to deal
with the 3rd scenario plus an i2c driver to deal with #1 and #2, by
querying the CLDB buffer found against INT3472 entries to determine
which is most appropriate.

This driver was originally intended to support some HP laptops, but
later support was added for Xioami and AMD laptops.
Rename it to make it clear that it supports a larger variety of
systems.

Tested with
* X570 I Aorus Pro Wifi (rev 1.0)
* B550M DS3H
* B550 Gaming X V2 (rev.1.x)
* Z390 I AORUS PRO WIFI (rev. 1.0)
Those mainboards contain an ITE chips for management and
monitoring.
They could also be handled by drivers/hwmon/i87.c.
But the SuperIO range used by i87 is already claimed and used by the
firmware.
The following warning is printed at boot:
kernel: ACPI Warning: SystemIO range 0x0000000000000A45-0x0000000000000A46 conflicts with OpRegion 0x0000000000000A45-0x0000000000000A46 (\GSA1.SIO1) (20200528/utaddress-204)
kernel: ACPI: This conflict may cause random problems and system instability
kernel: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
This driver implements such an ACPI driver.
Unfortunately not all sensor registers are handled by the firmware and even
less are exposed via WMI.

Advantech sw_button is a ACPI event trigger button.
With this driver, we can report KEY_PROG1 on the
Advantech Tabletop Network Appliances products and it has been
tested in FWA1112VC.
Add the software define button support to report EV_REP key_event
(KEY_PROG1) by pressing button that could be get on user
interface and trigger the customized actions.

A user without a Dell system doesn't need to pick any of these

Users with a Dell system can enable this submenu and all drivers

The ACPI-enabled Intel MID platforms neither have WDAT table nor proper IDs
to instantiate watchdog device. In order to keep them working move the board
code from arch/x86 to drivers/platform/x86.
Note, the complete SFI support is going to be removed, that's why PDx86
has been chosen as a new home for it. This is the only device which needs
additional code so far.

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. The commit
05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align
with this theory.
Due to above and to reduce a burden of supporting outdated drivers
we remove the support of outdated platforms completely.

Add the uv_sysfs driver to construct a read-only sysfs interface at
/sys/firmware/sgi_uv/ to expose information gathered from UV BIOS. This
information includes:
* UV Hub descriptions, including physical location
* Cabling layout between hubs on the fabric
* PCI topology, including physical location of PCI cards
Together, the information provides a robust physical description of a UV
system, useful for correlating to performance data or performing remote
support.

AMD Power Management Controller driver a.k.a. amd-pmc driver is the
controller which is meant for the final S2Idle transaction that goes to
the PMFW running on the AMD SMU (System Management Unit) responsible for
tuning of the VDD.
Once all the monitored list or the idle constraints are met, this driver
would go and set the OS_HINT (meaning all the devices have reached to
their lowest state possible) via the SMU mailboxes.
This driver would also provide some debug capabilities via debugfs.
