0a6509b092 platform/x86: Add Asus TF103C dock driver
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.

55fa3c9665 platform/x86: x86-android-tablets: New driver for x86 Android tablets
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.

dd123e62bd platform/x86: simatic-ipc: add main driver for Siemens devices
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.

c0549b72d9 platform/x86: lenovo-yogabook-wmi: Add driver for Lenovo Yoga Book
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

86af1d02d4 platform/x86: Support for EC-connected GPIOs for identify LED/button on 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)
I: Bus=0019 Vendor=0001 Product=0001 Version=0100
N: Name="identify"
P: Phys=gpio-keys-polled/input0
S: Sysfs=/devices/platform/barco-p50-gpio/gpio-keys-polled/input/input10

f809891ee5 platform/x86: thinkpad_acpi: Register a privacy-screen device
Register a privacy-screen device on laptops with a privacy-screen,
this exports the PrivacyGuard features to user-space using a
standardized vendor-agnostic sysfs interface. Note the sysfs interface
is read-only.

Registering a privacy-screen device with the new privacy-screen class
code will also allow the GPU driver to get a handle to it and export
the privacy-screen setting as a property on the DRM connector object
for the LCD panel. This DRM connector property is a new standardized
interface which all user-space code should use to query and control
the privacy-screen.

ad62cd9319 platform/x86: Add driver for ACPI WMAA EC-based backlight control
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.

4c51ba9af4 platform/x86: hp-wmi: add support for omen laptops
This patch adds support for HP Omen laptops.
It adds support for most things that can be controlled via the
Windows Omen Command Center application.

 - Fan speed monitoring through hwmon
 - Platform Profile support (cool, balanced, performance)
 - Max fan speed function toggle

Also exposes the existing HDD temperature through hwmon since
this driver didn't use hwmon before this patch.

This patch has been tested on a 2020 HP Omen 15 (AMD) 15-en0023dx.

 - V1
   Initial Patch
 - V2
   Use standard hwmon ABI attributes
   Add existing non-standard "hddtemp" to hwmon
 - V3
   Fix overflow issue in "hp_wmi_get_fan_speed"
   Map max fan speed value back to hwmon values on read
   Code style fixes
   Fix issue with returning values from "hp_wmi_hwmon_read",
   the value to return should be written to val and not just
   returned from the function
 - V4
   Use DMI Board names to detect if a device should use the omen
   specific thermal profile method.
   Select HWMON instead of depending on it.
   Code style fixes.
   Replace some error codes with more specific/meaningful ones.
   Remove the HDD temperature from HWMON since we don't know what
   unit it's expressed in.
   Handle error from hp_wmi_hwmon_init
 - V5
   Handle possible NULL from dmi_get_system_info()
   Use match_string function instead of manually checking
   Directly use is_omen_thermal_profile() without the static
   variable.

153cca9caa platform/x86: Add and use a dual_accel_detect() helper
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.

5de691bffe platform/x86: Add intel_skl_int3472 driver
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.

b68e182a30 platform/x86: intel_int0002_vgpio: Only call enable_irq_wake() when using s2idle
Commit 871f1f2bcb ("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.

This could probably be made optional, but it won't be used without
ACPI in practice, so just add a Kconfig dependency.

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.
