commit f5554725f30475b05b5178b998366f11ecb50c7f upstream.
Currently, rumble is only supported via bluetooth on a single xbox
controller, called 'model 1708'. On the back of the device, it's named
'wireless controller for xbox one'. However, in 2021, Microsoft released
a firmware update for this controller. As part of this update, the HID
descriptor of the device changed. The product ID was also changed from
0x02fd to 0x0b20. On this controller, rumble was supported via
hid-microsoft, which matched against the old product id (0x02fd). As a
result, the firmware update broke rumble support on this controller.
See:
https://news.xbox.com/en-us/2021/09/08/xbox-controller-firmware-update-rolling-out-to-insiders-starting-today/
The hid-microsoft driver actually supports rumble on the new firmware,
as well. So simply adding new product id is sufficient to bring back
this support.
After discussing further with the xbox team, it was pointed out that
another xbox controller, xbox elite series 2, can be supported in a
similar way.
Add rumble support for all of these devices in this patch. Two of the
devices have received firmware updates that caused their product id's to
change. Both old and new firmware versions of these devices were tested.
The tested controllers are:
1. 'wireless controller for xbox one', model 1708
2. 'xbox wireless controller', model 1914. This is also sometimes
referred to as 'xbox series S|X'.
3. 'elite series 2', model 1797.
The tested configurations are:
1. model 1708, pid 0x02fd (old firmware)
2. model 1708, pid 0x0b20 (new firmware)
3. model 1914, pid 0x0b13
4. model 1797, pid 0x0b05 (old firmware)
5. model 1797, pid 0x0b22 (new firmware)
I verified rumble support on both bluetooth and usb.

commit 1b8f9c1fb464968a5b18d3acc1da8c00bad24fad upstream.
The Wacom driver maps the HID_DG_TWIST usage to ABS_Z (rather than ABS_RZ)
for historic reasons. When the code to support twist was introduced in
commit 50066a042da5 ("HID: wacom: generic: Add support for height, tilt,
and twist usages"), we were careful to write it in such a way that it had
HID calculate the resolution of the twist axis assuming ABS_RZ instead
(so that we would get correct angular behavior). This was broken with
the introduction of commit 08a46b4190d3 ("HID: wacom: Set a default
resolution for older tablets"), which moved the resolution calculation
to occur *before* the adjustment from ABS_Z to ABS_RZ occurred.
This commit moves the calculation of resolution after the point that
we are finished setting things up for its proper use.

commit f0d17d696dfce77c9abc830e4ac2d677890a2dad upstream.
The pen ID, 0x80842, was not the correct ID for wacom driver to
treat. The ID was corrected to 0x8842.
Also, 0x4200 was not the expected ID used on any Wacom device.
Therefore, 0x4200 was removed.

Sensors discovery is independent of HID device initialization. If sensor
discovery fails after HID initialization, then the HID device needs to be
deinitialized. Therefore, sensors discovery should be moved before HID

[ Upstream commit 0eafc58f2194dbd01d4be40f99a697681171995b ]
The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s
shares the VCC33 supply with other peripherals that may remain powered
during suspend (e.g. when enabled as wakeup sources).
The reset line is also wired so that it can be left deasserted when the
supply is off.
This is important as it avoids holding the controller in reset for
extended periods of time when it remains powered, which can lead to
increased power consumption, and also avoids leaking current through the
X13s reset circuitry during suspend (and after driver unbind).
Use the new 'no-reset-on-power-off' devicetree property to determine
when reset needs to be asserted on power down.
Notably this also avoids wasting power on machine variants without a
touchscreen for which the driver would otherwise exit probe with reset
asserted.

[ Upstream commit f2f43bf15d7aa3286eced18d5199ee579e2c2614 ]
The ili9882t is a TDDI IC (Touch with Display Driver). The
datasheet specifies there should be 60ms between touch SDA
sleep and panel RESX. Doug's series[1] allows panels and
touchscreens to power on/off together, so we can add the 65 ms
delay in i2c_hid_core_suspend before panel_unprepare.
Because ili9882t touchscrgeen is a panel follower, and
needs to use vccio-supply instead of vcc33-supply, so set
it NULL to ili9882t_chip_data, then not use vcc33 regulator.

commit 9c0f59e47a90c54d0153f8ddc0f80d7a36207d0e upstream.
The flag I2C_HID_READ_PENDING is used to serialize I2C operations.
However, this is not necessary, because I2C core already has its own
locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in
i2c_hid_xfer() and an interrupt happens, the interrupt handler
(i2c_hid_irq) will check this flag and return immediately without doing
anything, then the interrupt handler will be invoked again in an
infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the
flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.

commit c1d6708bf0d3dd976460d435373cf5abf21ce258 upstream.
If a input device is opened before hid_hw_start is called, events may
not be received from the hardware. In the case of USB-backed devices,
for example, the hid_hw_start function is responsible for filling in
the URB which is submitted when the input device is opened. If a device
is opened prematurely, polling will never start because the device will
not have been in the correct state to send the URB.
Because the wacom driver registers its input devices before calling
hid_hw_start, there is a window of time where a device can be opened
and end up in an inoperable state. Some ARM-based Chromebooks in particular
reliably trigger this bug.
This commit splits the wacom_register_inputs function into two pieces.
One which is responsible for setting up the allocated inputs (and runs
prior to hid_hw_start so that devices are ready for any input events
they may end up receiving) and another which only registers the devices
(and runs after hid_hw_start to ensure devices can be immediately opened
without issue). Note that the functions to initialize the LEDs and remotes
are also moved after hid_hw_start to maintain their own dependency chains.

commit ab41a31dd5e2681803642b6d08590b61867840ec upstream.
The xf86-input-wacom driver does not treat '0' as a valid serial
number and will drop any input report which contains an
MSC_SERIAL = 0 event. The kernel driver already takes care to
avoid sending any MSC_SERIAL event if the value of serial[0] == 0
(which is the case for devices that don't actually report a
serial number), but this is not quite sufficient.
Only the lower 32 bits of the serial get reported to userspace,
so if this portion of the serial is zero then there can still
be problems.
This commit allows the driver to report either the lower 32 bits
if they are non-zero or the upper 32 bits otherwise.

commit 502296030ec6b0329e00f9fb15018e170cc63037 upstream.
There appear to be a few different ways that Wacom devices can deal with
confidence:
1. If the device looses confidence in a touch, it will first clear
the tipswitch flag in one report, and then clear the confidence
flag in a second report. This behavior is used by e.g. DTH-2452.
2. If the device looses confidence in a touch, it will clear both
the tipswitch and confidence flags within the same report. This
behavior is used by some AES devices.
3. If the device looses confidence in a touch, it will clear *only*
the confidence bit. The tipswitch bit will remain set so long as
the touch is tracked. This behavior may be used in future devices.
The driver does not currently handle situation 3 properly. Touches that
loose confidence will remain "in prox" and essentially frozen in place
until the tipswitch bit is finally cleared. Not only does this result
in userspace seeing a stuck touch, but it also prevents pen arbitration
from working properly (the pen won't send events until all touches are
up, but we don't currently process events from non-confident touches).
This commit centralizes the checking of the confidence bit in the
wacom_wac_finger_slot() function and has 'prox' depend on it. In the
case where situation 3 is encountered, the treat the touch as though
it was removed, allowing both userspace and the pen arbitration to
act normally.

It was reported [0] that adding a generic joycon to the system caused
a kernel crash on Steam Deck, with the below panic spew:

Since it's a divide-by-0 error, by tracking the code for potential
denominator issues, we've spotted 2 places in which this could happen;
so let's guard against the possibility and log in the kernel if the
condition happens. This is specially useful since some data that
fills some denominators are read from the joycon HW in some cases,
increasing the potential for flaws.

[ Upstream commit a9f68ffe1170ca4bc17ab29067d806a354a026e0 ]
Users have reported problems with recent Lenovo laptops that contain
an IDEA5002 I2C HID device. Reports include fans turning on and
running even at idle and spurious wakeups from suspend.
Presumably in the Windows ecosystem there is an application that
uses the HID device. Maybe that puts it into a lower power state so
it doesn't cause spurious events.
This device doesn't serve any functional purpose in Linux as nothing
interacts with it so blacklist it from being probed. This will
prevent the GPIO driver from setting up the GPIO and the spurious
interrupts and wake events will not occur.

The touchpad reports as BLTP7853, which cannot retrive any useful manufacture

the laptop is GLO-G52, while DMI info reports the laptop serial number as
GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.

Some devices managed by this driver automatically set brightness to 0
before entering a suspended state and reset it back to a default

this has the effect of having the kernel report wrong brightness

brightness is the intensity of LEDs directly facing the user.

[ Upstream commit a5e913c25b6b2b6ae02acef6d9400645ac03dfdf ]
The Glorious Model I mouse has a buggy HID report descriptor for its
keyboard endpoint (used for programmable buttons). For report ID 2, there
is a mismatch between Logical Minimum and Usage Minimum in the array that
reports keycodes.
The offending portion of the descriptor: (from hid-decode)
0x95, 0x05, // Report Count (5) 30
0x75, 0x08, // Report Size (8) 32
0x15, 0x00, // Logical Minimum (0) 34
0x25, 0x65, // Logical Maximum (101) 36
0x05, 0x07, // Usage Page (Keyboard) 38
0x19, 0x01, // Usage Minimum (1) 40
0x29, 0x65, // Usage Maximum (101) 42
0x81, 0x00, // Input (Data,Arr,Abs) 44
This bug shifts all programmed keycodes up by 1. Importantly, this causes
"empty" array indexes of 0x00 to be interpreted as 0x01, ErrorRollOver.
The presence of ErrorRollOver causes the system to ignore all keypresses
from the endpoint and breaks the ability to use the programmable buttons.
Setting byte 41 to 0x00 fixes this, and causes keycodes to be interpreted
correctly.
Also, USB_VENDOR_ID_GLORIOUS is changed to USB_VENDOR_ID_SINOWEALTH,
and a new ID for Laview Technology is added. Glorious seems to be
white-labeling controller boards or mice from these vendors. There isn't a
single canonical vendor ID for Glorious products.

commit 2f2bd7cbd1d1548137b351040dc4e037d18cdfdc upstream.
The USB Compact Keyboard variant requires a reset_resume function to
restore keyboard configuration after a suspend in some situations. Move
configuration normally done on probe to lenovo_features_set_cptkbd(), then
recycle this for use on reset_resume.
Without, the keyboard and driver would end up in an inconsistent state,
breaking middle-button scrolling amongst other problems, and twiddling
sysfs values wouldn't help as the middle-button mode won't be set until
the driver is reloaded.
Tested on a USB and Bluetooth Thinkpad Compact Keyboard.

[ Upstream commit 46a0a2c96f0f47628190f122c2e3d879e590bcbe ]
Built-in firmware of cptkbd handles scrolling by itself (when middle
button is pressed) but with issues: it does not support horizontal and
hi-res scrolling and upon middle button release it sends middle button
click even if there was a scrolling event. Commit 3cb5ff0220e3 ("HID:
lenovo: Hide middle-button press until release") workarounds last
issue but it's impossible to workaround scrolling-related issues
without firmware modification.
Likely, Dennis Schneider has reverse engineered the firmware and
provided an instruction on how to patch it [1]. However,
aforementioned workaround prevents userspace (libinput) from knowing
exact moment when middle button has been pressed down and performing
"On-Button scrolling". This commit detects correctly-behaving patched
firmware if cursor movement events has been received during middle
button being pressed and stops applying workaround for this device.

hidpp_connect_event()
[ Upstream commit ba9de350509504fb748837b71e23d7e84c83d93c ]
Calling get_wireless_feature_index() from probe() causes
the wireless_feature_index to only get set for unifying devices which
are already connected at probe() time. It does not get set for devices
which connect later.
Fix this by moving get_wireless_feature_index() to hidpp_connect_event(),
this does not make a difference for devices connected at probe() since
probe() will queue the hidpp_connect_event() for those at probe time.
This series has been tested on the following devices:

[ Upstream commit 55bf70362ffc4ddd7c8745e2fe880edac00e4aff ]
Commit 91cf9a98ae41 ("HID: logitech-hidpp: make .probe usbhid capable")
makes hidpp_probe() first call hid_hw_start(hdev, 0) to allow IO
without connecting any hid subdrivers (hid-input, hidraw).
This is done to allow to retrieve the device's name and serial number
and store these in hdev->name and hdev->uniq.
Then later on IO was stopped and started again with hid_hw_start(hdev,
HID_CONNECT_DEFAULT) connecting hid-input and hidraw after the name
and serial number have been setup.
Commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication
if not necessary") changed the probe() code to only do the start with
a 0 connect-mask + restart later for unifying devices.
But for non unifying devices hdev->name and hdev->uniq are updated too.
So this change re-introduces the problem for which the start with
a 0 connect-mask + restart later behavior was introduced.
The previous patch in this series changes the unifying path to instead of
restarting IO only call hid_connect() later. This avoids possible issues
with restarting IO seen on non unifying devices.
Revert the change to limit the restart behavior to unifying devices to
fix hdev->name changing after userspace facing devices have already been
registered.

[ Upstream commit 11ca0322a41920df2b462d2e45b0731e47ff475b ]
Restarting IO causes 2 problems:
1. Some devices do not like IO being restarted this was addressed in
commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication
if not necessary"), but that change has issues of its own and needs to
be reverted.
2. Restarting IO and specifically calling hid_device_io_stop() causes
received packets to be missed, which may cause connect-events to
get missed.
Restarting IO was introduced in commit 91cf9a98ae41 ("HID: logitech-hidpp:
make .probe usbhid capable") to allow to retrieve the device's name and
serial number and store these in hdev->name and hdev->uniq before
connecting any hid subdrivers (hid-input, hidraw) exporting this info
to userspace.
But this does not require restarting IO, this merely requires deferring
calling hid_connect(). Calling hid_hw_start() with a connect-mask of
0 makes it skip calling hid_connect(), so hidpp_probe() can simply call
hid_connect() later without needing to restart IO.
Remove the stop + restart of IO and instead just call hid_connect() later
to avoid the issues caused by restarting IO.
Now that IO is no longer stopped, hid_hw_close() must be called at the end
of probe() to balance the hid_hw_open() done at the beginning probe().
This series has been tested on the following devices:
Logitech Bluetooth Laser Travel Mouse (bluetooth, HID++ 1.0)
Logitech M720 Triathlon (bluetooth, HID++ 4.5)
Logitech M720 Triathlon (unifying, HID++ 4.5)
Logitech K400 Pro (unifying, HID++ 4.1)
Logitech K270 (eQUAD nano Lite, HID++ 2.0)
Logitech M185 (eQUAD nano Lite, HID++ 4.5)
Logitech LX501 keyboard (27 Mhz, HID++ builtin scroll-wheel, HID++ 1.0)
Logitech M-RAZ105 mouse (27 Mhz, HID++ extra mouse buttons, HID++ 1.0)
And by bentiss:
Logitech Touchpad T650 (unifying)
Logitech Touchpad T651 (bluetooth)
Logitech MX Master 3B (BLE)
Logitech G403 (plain USB / Gaming receiver)

[ Upstream commit d83956c8855c6c2ed4bd16cec4a5083d63df17e4 ]
HIDPP_QUIRK_NO_HIDINPUT isn't used by any devices but still happens to
work as HIDPP_QUIRK_DELAYED_INIT is defined to the same value. Remove
HIDPP_QUIRK_NO_HIDINPUT and use HIDPP_QUIRK_DELAYED_INIT everywhere
instead.
Tested on a T650 which requires that quirk, and a number of unifying and
Bluetooth devices that don't.

[ Upstream commit cae253d6033da885e71c29c1591b22838a52de76 ]
Now that we're in 2022, and the majority of desktop environments can and
should support touchpad gestures through libinput, remove the legacy
module parameter that made it possible to use gestures implemented in
firmware.
This will eventually allow simplifying the driver's initialisation code.
This reverts commit 9188dbaed68a4b23dc96eba165265c08caa7dc2a.

[ Upstream commit dc3115e6c5d9863ec1a9ff1acf004ede93c34361 ]
Previously cp2112_gpio_irq_shutdown() always cancelled the
gpio_poll_worker, even if other IRQs were still active, and did not set
the gpio_poll flag to false. This resulted in any call to _shutdown()
resulting in interrupts no longer functioning on the chip until a
_remove() occurred (a.e. the cp2112 is unplugged or system rebooted).
Only cancel polling if all IRQs are disabled/masked, and correctly set
the gpio_poll flag, allowing polling to restart when an interrupt is
next enabled.

[ Upstream commit 3e2977c425ad2789ca18084fff913cceacae75a2 ]
Since recently, the kernel is nagging about mutable irq_chips:
"not an immutable chip, please consider fixing it!"
Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new
helper functions and call the appropriate gpiolib functions.
