commit 085fc31f81765e061c78cdcab0e5516fd672bff7 upstream.
360 degree hinges devices with dual KIOX010A + KIOX020A accelerometers
always have both a KIOX010A and a KIOX020A ACPI device (one for each
accel).
Theoretical some vendor may re-use some DSDT for a non-convertible
stripping out just the KIOX020A ACPI device from the DSDT. Check that
both ACPI devices are present to make the check more robust.

module option
[ Upstream commit 7f45621c14a209b986cd636447bb53b7f6f881c3 ]
Unfortunately we have been unable to find a reliable way to detect if
and how SW_TABLET_MODE reporting is supported, so we are relying on
DMI quirks for this.
Add a module-option to specify the SW_TABLET_MODE method so that this can
be easily tested without needing to rebuild the kernel.

[ Upstream commit 153cca9caa81ca8912a70528daca4b9a523c6898 ]
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.

gpio-lookup tables
[ Upstream commit 9d7b132e62e41b7d49bf157aeaf9147c27492e0f ]
The gpiod_lookup_table.table passed to gpiod_add_lookup_table() must
be terminated with an empty entry, add this.
Note we have likely been getting away with this not being present because
the GPIO lookup code first matches on the dev_id, causing most lookups to
skip checking the table and the lookups which do check the table will
find a matching entry before reaching the end. With that said, terminating
these tables properly still is obviously the correct thing to do.

G15"
[ Upstream commit 28117f3a5c3c8375a3304af76357d5bf9cf30f0b ]
The quirks added to asus-nb-wmi for the ASUS ROG Zephyrus G14 and G15 are
wrong, they tell the asus-wmi code to use the vendor specific WMI backlight
interface. But there is no such interface on these laptops.
As a side effect, these quirks stop the acpi_video driver to register since
they make acpi_video_get_backlight_type() return acpi_backlight_vendor,
leaving only the native AMD backlight driver in place, which is the one we
want. This happy coincidence is being replaced with a new quirk in
drivers/acpi/video_detect.c which actually sets the backlight_type to
acpi_backlight_native fixinf this properly. This reverts
commit 13bceda68fb9 ("platform/x86: asus-nb-wmi: add support for ASUS ROG

TM800A550L tablets
[ Upstream commit fcd8cf0e3e48f4c66af82c8e799c37cb0cccffe0 ]
The Bay Trail Glavey TM800A550L tablet, which ships with Android installed
from the factory, uses a GT912 touchscreen controller which needs to have
its firmware uploaded by the OS to work (this is a first for a x86 based
device with a Goodix touchscreen controller).
Add a touchscreen_dmi entry for this which specifies the filenames
to use for the firmware and config files needed for this.
Note this matches on a GDIX1001 ACPI HID, while the original DSDT uses
a HID of GODX0911. For the touchscreen to work on these devices a DSDT
override is necessary to fix a missing IRQ and broken GPIO settings in
the ACPI-resources for the touchscreen. This override also changes the
HID to the standard GDIX1001 id typically used for Goodix touchscreens.
The DSDT override is available here:

touchscreen on Teclast X89 tablets
[ Upstream commit a22e3803f2a4d947ff0083a9448a169269ea0f62 ]
Teclast X89 tablets come in 2 versions, with Windows pre-installed and with
Android pre-installed. These 2 versions have different DMI strings.
Add a match for the DMI strings used by the Android version BIOS.
Note the Android version BIOS has a bug in the DSDT where no IRQ is
provided, so for the touchscreen to work a DSDT override fixing this
is necessary as well.

touchscreen_dmi.c
[ Upstream commit 5a6f0dbe621a5c20dc912ac474debf9f11129e03 ]
Move the DMI quirks for upside-down mounted Goodix touchscreens from
drivers/input/touchscreen/goodix.c to
drivers/platform/x86/touchscreen_dmi.c,
where all the other x86 touchscreen quirks live.
Note the touchscreen_dmi.c code attaches standard touchscreen
device-properties to an i2c-client device based on a combination of a
DMI match + a device-name match. I've verified that the: Teclast X98 Pro,
WinBook TW100 and WinBook TW700 uses an ACPI devicename of "GDIX1001:00"
based on acpidumps and/or dmesg output available on the web.
This patch was tested on a Teclast X89 tablet.

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.

The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."
I recently receive a patch to explicitly add a new one.
Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.
It is even nicer if scripts/checkpatch.pl can check it.
If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.

pmc_core_lpm_latch_mode_write()
The simple_write_to_buffer() can return success if even a single byte
is copied from user space. In this case it can result in using
uninitalized data if the buf[] array is not fully initialized. Really
we should only succeed if the whole buffer is copied.
Just using copy_from_user() is simpler and more appropriate.

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

By default the Low Power Mode (LPM or sub-state) status registers will
latch condition status on every entry into Package C10. This is
configurable in the PMC to allow latching on any achievable sub-state. Add
a debugfs file to support this.
Also add the option to clear the status registers to 0. Clearing the status
registers before testing removes ambiguity around when the current values
were set.
The new file, latch_lpm_mode, looks like this:

Platforms that support low power modes (LPM) such as Tiger Lake maintain
requirements for each sub-state that a readable in the PMC. However, unlike
LPM status registers, requirement registers are not memory mapped but are
available from an ACPI _DSM. Collect the requirements for Tiger Lake using
the _DSM method and store in a buffer.

The current implementation of pmc_core_substate_res_show() is written
specifically for Tiger Lake. However, new platform will also have
sub-states and may support different modes. Therefore rewrite the code to
handle sub-states generically.
Obtain the number and type of enabled states form the PMC. Use the Low
Power Mode (LPM) priority register to store the states in order from
shallowest to deepest for displays. Add a for_each macro to simplify
this. While changing the sub-state display it makes sense to show only the
"enabled" sub-states instead of showing all possible ones. After this
patch, the debugfs file looks like this:
Substate Residency
S0i2.0 0
S0i3.0 0
S0i2.1 9329279
S0i3.1 0

The intel_pmc_core driver did not always bind to a device which meant it
lacked a struct device that could be used to maintain driver data. So a
global instance of struct pmc_dev was used for this purpose and functions
accessed this directly. Since the driver now binds to an ACPI device,
remove the global pmc_dev in favor of one that is allocated during probe.
Modify users of the global to obtain the object by argument instead.

The DMI callbacks, used for quirks, currently access the PMC by getting
the address a global pmc_dev struct. Instead, have the callbacks set a
global quirk specific variable. In probe, after calling dmi_check_system(),
pass pmc_dev to a function that will handle each quirk if its variable
condition is met. This allows removing the global pmc_dev later.
