Add initial support for platform_profile where the support is
based on availability of ASUS_THROTTLE_THERMAL_POLICY.
Because throttle_thermal_policy is used by platform_profile and is
writeable separately to platform_profile any userspace changes to
throttle_thermal_policy need to notify platform_profile.
In future throttle_thermal_policy sysfs should be removed so that
only one method controls the laptop power profile.

Various 360 degree hinges (yoga) style 2-in-1 devices use 2 accelerometers
to allow the OS to determine the angle between the display and the base of
the device.
On Windows these are read by a special HingeAngleService process which
calls undocumented ACPI methods, to let the firmware know if the 2-in-1 is
in tablet- or laptop-mode. The firmware may use this to disable the kbd and
touchpad to avoid spurious input in tablet-mode as well as to report
SW_TABLET_MODE info to the OS.
Since Linux does not call these undocumented methods, the SW_TABLET_MODE
info reported by various pdx86 drivers is incorrect on these devices.
Before this commit the intel-hid and thinkpad_acpi code already had 2
hardcoded checks for ACPI hardware-ids of dual-accel sensors to avoid
reporting broken info.
And now we also have a bug-report about the same problem in the intel-vbtn
code. Since there are at least 3 different ACPI hardware-ids in play, add
a new dual_accel_detect() helper which checks for all 3, rather then
adding different hardware-ids to the drivers as bug-reports trickle in.
Having shared code which checks all known hardware-ids is esp. important
for the intel-hid and intel-vbtn drivers as these are generic drivers
which are used on a lot of devices.
The BOSC0200 hardware-id requires special handling, because often it is
used for a single-accelerometer setup. Only in a few cases it refers to
a dual-accel setup, in which case there will be 2 I2cSerialBus resources
in the device's resource-list, so the helper checks for this.

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.

Commit 871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") stopped passing irq_set_wake requests on to
the parents IRQ because this was breaking suspend (causing immediate
wakeups) on an Asus E202SA.
This workaround for the Asus E202SA is causing wakeup by USB keyboard to
not work on other devices with Airmont CPU cores such as the Medion Akoya
E1239T. In hindsight the problem with the Asus E202SA has nothing to do
with Silvermont vs Airmont CPU cores, so the differentiation between the
2 types of CPU cores introduced by the previous fix is wrong.
The real issue at hand is s2idle vs S3 suspend where the suspend is
mostly handled by firmware. The parent IRQ for the INT0002 device is shared
with the ACPI SCI and the real problem is that the INT0002 code should not
be messing with the wakeup settings of that IRQ when suspend/resume is
being handled by the firmware.
Note that on systems which support both s2idle and S3 suspend, which
suspend method to use can be changed at runtime.
This patch fixes both the Asus E202SA spurious wakeups issue as well as
the wakeup by USB keyboard not working on the Medion Akoya E1239T issue.
These are both fixed by replacing the old workaround with delaying the
enable_irq_wake(parent_irq) call till system-suspend time and protecting
it with a !pm_suspend_via_firmware() check so that we still do not call
it on devices using firmware-based (S3) suspend such as the Asus E202SA.
Note rather then adding #ifdef CONFIG_PM_SLEEP, this commit simply adds
a "depends on PM_SLEEP" to the Kconfig since this drivers whole purpose
is to deal with wakeup events, so using it without CONFIG_PM_SLEEP makes
no sense.

depends on
With the #if IS_ENABLED(CONFIG_ACPI_PLATFORM_PROFILE), we get the following
errors when thinkpad_acpi is builtin while CONFIG_ACPI_PLATFORM_PROFILE=m :
drivers/platform/x86/thinkpad_acpi.c:10186: undefined reference to `platform_profile_notify'

This could be fixed by changing the IS_ENABLED to IS_REACHABLE, but
I believe that it is better to just switch to using depends on.
Using depends on ensures that platform-profile support is always
available when thinkpad_acpi is build, hopefully leading to less
confusing bug-reports about it sometimes not working.

Add support to ideapad-laptop for Lenovo platforms that have DYTC
version 5 support or newer to use the platform profile feature.
Mostly based on Mark Pearson <markpearson@lenovo.com>'s thinkpad-acpi
work but massaged to fit ideapad driver.
Note that different from ThinkPads, IdeaPads's Thermal Hotkey won't
trigger profile switch itself, we'll leave it for userspace programs.
Tested on Lenovo Yoga-14S ARE Chinese Edition.

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 a more or less fresh kernel on it.
Commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") which has
been upstream for a while now confirms this theory.
Due to above and to reduce a burden of supporting outdated drivers
we remove the support of outdated platforms completely.

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.

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.

Add support for the Intel Platform Monitoring Technology crashlog
interface. This interface provides a few sysfs values to allow for
controlling the crashlog telemetry interface as well as a character
driver to allow for mapping the crashlog memory region so that it can be
accessed after a crashlog has been recorded.
This driver is meant to only support the server version of the crashlog
which is identified as crash_type 1 with a version of zero. Currently no
other types are supported.

PMT Telemetry is a capability of the Intel Platform Monitoring Technology.
The Telemetry capability provides access to device telemetry metrics that
provide hardware performance data to users from read-only register spaces.
With this driver present the intel_pmt directory can be populated with
telem<x> devices. These devices will contain the standard intel_pmt sysfs
data and a "telem" binary sysfs attribute which can be used to access the
telemetry data.
Also create a PCI device id list for early telemetry hardware that require
workarounds for known issues.
