4c775b4cd8 Input: soc_button_array - add mapping for airplane mode button
commit ea3715941a9b7d816a1e9096ac0577900af2a69e upstream.

This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.

While it is physically a key it behaves more like a switch, sending a key
down on first press and a key up on 2nd press. Therefor the switch event
is used here. Besides this behaviour it uses the HID usage-id 0xc6
(Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but
since neither 0xc6 nor 0xc8 are currently implemented at all in
soc_button_array this not to standard behaviour is not put behind a quirk
for the moment.

dd6d75eb00 Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsport
[ Upstream commit 5030b2fe6aab37fe42d14f31842ea38be7c55c57 ]

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.

SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.

Note that originally the delay was added to psmouse driver in
92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

862aa98181 Input: goodix - ensure int GPIO is in input for gpio_count == 1 && gpio_int_idx == 0 case
commit 423622a90abb243944d1517b9f57db53729e45c4 upstream.

Add a special case for gpio_count == 1 && gpio_int_idx == 0 to
goodix_add_acpi_gpio_mappings().

It seems that on newer x86/ACPI devices the reset and irq GPIOs are no
longer listed as GPIO resources instead there is only 1 GpioInt resource
and _PS0 does the whole reset sequence for us.

This means that we must call acpi_device_fix_up_power() on these devices
to ensure that the chip is reset before we try to use it.

This part was already fixed in commit 3de93e6ed2df ("Input: goodix - call
acpi_device_fix_up_power() in some cases") by adding a call to
acpi_device_fix_up_power() to the generic "Unexpected ACPI resources"
catch all.

But it turns out that this case on some hw needs some more special
handling. Specifically the firmware may bootup with the IRQ pin in
output mode. The reset sequence from ACPI _PS0 (executed by
acpi_device_fix_up_power()) should put the pin in input mode,
but the GPIO subsystem has cached the direction at bootup, causing
request_irq() to fail due to gpiochip_lock_as_irq() failure:

[    9.119864] Goodix-TS i2c-GDIX1002:00: Unexpected ACPI resources: gpio_count 1, gpio_int_idx 0
[    9.317443] Goodix-TS i2c-GDIX1002:00: ID 911, version: 1060
[    9.321902] input: Goodix Capacitive TouchScreen as /devices/pci0000:00/0000:00:17.0/i2c_designware.4/i2c-5/i2c-GDIX1002:00/input/input8
[    9.327840] gpio gpiochip0: (INT3453:00): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ
[    9.327856] gpio gpiochip0: (INT3453:00): unable to lock HW IRQ 26 for IRQ
[    9.327861] genirq: Failed to request resources for GDIX1002:00 (irq 131) on irqchip intel-gpio
[    9.327912] Goodix-TS i2c-GDIX1002:00: request IRQ failed: -5

Fix this by adding a special case for gpio_count == 1 && gpio_int_idx == 0
which adds an ACPI GPIO lookup table for the int GPIO even though we cannot
use it for reset purposes (as there is no reset GPIO).

Adding the lookup will make the gpiod_int = gpiod_get(..., GPIOD_IN) call
succeed, which will explicitly set the direction to input fixing the issue.

Note this re-uses the acpi_goodix_int_first_gpios[] lookup table, since
there is only 1 GPIO in the ACPI resources the reset entry in that
lookup table will amount to a no-op.

commit 80f39e1c27ba9e5a1ea7e68e21c569c9d8e46062 upstream.

In the initial boot stage the integrated keyboard of Fujitsu Lifebook E5411
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.

i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:308A) not working at all.

Since the integrated touchpad is managed by the i2c_designware input
driver in the Linux kernel and you can't find a PS/2 mouse port on the
computer I think it's safe to not use the PS/2 mouse port at all.

211f71c1c0 Input: psmouse - fix fast_reconnect function for PS/2 mode
commit e2cb5cc822b6c9ee72c56ce1d81671b22c05406a upstream.

When the SMBus connection is attempted psmouse_smbus_init() sets
the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus
initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will
fallback to PS/2 mode, replacing the psmouse private data. This can cause
issues on resume, since psmouse_smbus_reconnect() expects to find an
instance of struct psmouse_smbus_dev in psmouse->private.

The issue was uncovered when in 92e24e0e57f7 ("Input: psmouse - add
delay when deactivating for SMBus mode") psmouse_smbus_reconnect()
started attempting to use more of the data structure. The commit was
since reverted, not because it was at fault, but because there was found
a better way of doing what it was attempting to do.

Fix the problem by resetting the fast_reconnect pointer in psmouse
structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2
mode is used.

commit 5c15c60e7be615f05a45cd905093a54b11f461bc upstream.

syzbot has found a use-after-free bug [1] in the powermate driver. This
happens when the device is disconnected, which leads to a memory free from
the powermate_device struct.  When an asynchronous control message
completes after the kfree and its callback is invoked, the lock does not
exist anymore and hence the bug.

Use usb_kill_urb() on pm->config to cancel any in-progress requests upon
device disconnection.

If the device drops into ultra-low-power mode before being placed
into normal-power mode as part of ATI being triggered, the device
does not assert any interrupts until the ATI routine is restarted
two seconds later.

Solve this problem by adopting the vendor's recommendation, which
calls for the device to be placed into normal-power mode prior to
being configured and ATI being triggered.

The original implementation followed this sequence, but the order
was inadvertently changed as part of the resolution of a separate

commit eb09074bdb05ffd6bfe77f8b4a41b76ef78c997b upstream.

The touchpad of this device is both connected via PS/2 and i2c. This causes
strange behavior when both driver fight for control. The easy fix is to
prevent the PS/2 driver from accessing the mouse port as the full feature
set of the touchpad is only supported in the i2c interface anyway.

The strange behavior in this case is, that when an external screen is
connected and the notebook is closed, the pointer on the external screen is
moving to the lower right corner. When the notebook is opened again, this
movement stops, but the touchpad clicks are unresponsive afterwards until
reboot.

commit feee70f4568650cf44c573488798ffc0a2faeea3 upstream.

While doing my research to improve the xpad device names I noticed
that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013,
so that Razer Sabertooth instance looked wrong and very suspect to
me. I didn't see any mention in the official drivers, either.

After doing more research, it turns out that the xpad list
is used by many other projects (like Steam) as-is [1], this
issue was reported [2] and Valve/Sam Lantinga fixed it [3]:

[1]: dcc5eef0e2/src/joystick/controller_type.h (L251)

[3]: https://hg.libsdl.org/SDL/rev/29809f6f0271

(With multiple Internet users reporting similar issues, not linked here)

After not being able to find the correct VID/PID combination anywhere
on the Internet and not receiving any reply from Razer support I did
some additional detective work, it seems like it presents itself as
"Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00.

Leaving us with this:
 * Razer Sabertooth (1689:fe00)
 * Razer Sabertooth Elite (24c6:5d04)
 * Razer DeathAdder 2013 (1532:0037) [note: not a gamepad]

So, to sum things up; remove this conflicting/duplicate entry:

{ 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 },

As the real/correct one is already present there, even if
the Internet as a whole insists on presenting it as the
Razer Sabertooth Elite, which (by all accounts) is not:

{ 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 },

The Android Lenovo Yoga Book X90F / X90L uses the same goodix touchscreen
with 9 bytes touch reports for its touch keyboard as the already supported
Windows Lenovo Yoga Book X91F/L, add a DMI match for this to
the nine_bytes_report DMI table.

When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to
the X91F/L models.

commit 754ff5060daf5a1cf4474eff9b4edeb6c17ef7ab upstream.

The AlpsPS/2 code previously relied on the assumption that `char` is a
signed type, which was true on x86 platforms (the only place where this
driver is used) before kernel 6.2. However, on 6.2 and later, this
assumption is broken due to the introduction of -funsigned-char as a new
global compiler flag.

Fix this by explicitly specifying the signedness of `char` when sign
extending the values received from the device.

commit cbedf1a33970c9b825ae75b81fbd3e88e224a418 upstream.

A lot of modern Clevo barebones have touchpad and/or keyboard issues after
suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them
have an external PS/2 port so this can safely be set for all of them.

I'm not entirely sure if every device listed really needs all four quirks,
but after testing and production use, no negative effects could be
observed when setting all four.

Setting SERIO_QUIRK_NOMUX or SERIO_QUIRK_RESET_ALWAYS on the Clevo N150CU
and the Clevo NHxxRZQ makes the keyboard very laggy for ~5 seconds after
boot and sometimes also after resume. However both are required for the
keyboard to not fail completely sometimes after boot or resume.

201d1baa9a Input: iqs7222 - drop unused device node references
[ Upstream commit bbd16b0d839978e8c8bec2b9a162373f64fc2fbb ]

Each call to device/fwnode_get_named_child_node() must be matched
with a call to fwnode_handle_put() once the corresponding node is
no longer in use. This ensures a reference count remains balanced
in the case of dynamic device tree support.

Currently, the driver never calls fwnode_handle_put(). Solve this
problem by moving the node handling from iqs7222_parse_props() to
the new iqs7222_parse_reg_grp(), leaving the former to do nothing
but parse properties. The latter then manages the reference count
in a single location and consistent fashion.

This change drastically simplifies iqs7222_parse_all(), which can
then call iqs7222_parse_reg_grp() on every register group without
having to treat each register group differently.

For nested event nodes, common parsing code has been factored out
to the new iqs7222_parse_event() so as to allow the event node to
be dropped from as few locations as possible.

As part of this refactor, the 'linux,code' property has been made
optional. This enables applications that define an event with the
sole purpose of enabling a GPIO.

[ Upstream commit a85fbd6498441694475716a4d5c65f9d3e073faf ]

As can be seen in elants_i2c_power_off(), we want the reset GPIO
asserted when power is off. The reset GPIO is active low so we need
the reset line logic low when power is off to avoid leakage.

We have a problem, though, at probe time. At probe time we haven't
powered the regulators on yet but we have:

  devm_gpiod_get(&client->dev, "reset", GPIOD_OUT_LOW);

While that _looks_ right, it turns out that it's not. The
GPIOD_OUT_LOW doesn't mean to init the GPIO to low. It means init the
GPIO to "not asserted". Since this is an active low GPIO that inits it
to be high.

Let's fix this to properly init the GPIO. Now after both probe and
power off the state of the GPIO is consistent (it's "asserted" or
level low).

Once we fix this, we can see that at power on time we no longer to
assert the reset GPIO as the first thing. The reset GPIO is _always_
asserted before powering on. Let's fix powering on to account for
this.

Avoid resetting the module-wide i8042_platform_device pointer in
i8042_probe() or i8042_remove(), so that the device can be properly
destroyed by i8042_exit() on module unload.

There are yet a few more ASUS ZenBook models that require the deferred
probe.  At least, there are different ZenBook UX325x and UX425x
models.  Let's extend the DMI matching table entries for adapting
those missing models.

e13757f524 Input: soc_button_array - add Acer Switch V 10 to dmi_use_low_level_irq[]
Like on the Acer Switch 10 SW5-012, the Acer Switch V 10 SW5-017's _LID
method messes with home- and power-button GPIO IRQ settings, causing an
IRQ storm.

Add a quirk entry for the Acer Switch V 10 to the dmi_use_low_level_irq[]
DMI quirk list, to use low-level IRQs on this model, fixing the IRQ storm.

8e9ada1d0e Input: soc_button_array - add use_low_level_irq module parameter
It seems that the Windows drivers for the ACPI0011 soc_button_array
device use low level triggered IRQs rather then using edge triggering.

Some ACPI tables depend on this, directly poking the GPIO controller's
registers to clear the trigger type when closing a laptop's/2-in-1's lid
and re-instating the trigger when opening the lid again.

Linux sets the edge/level on which to trigger to both low+high since
it is using edge type IRQs, the ACPI tables then ends up also setting
the bit for level IRQs and since both low and high level have been
selected by Linux we get an IRQ storm leading to soft lockups.

As a workaround for this the soc_button_array already contains
a DMI quirk table with device models known to have this issue.

Add a module parameter for this so that users can easily test if their
device is affected too and so that they can use the module parameter
as a workaround.

b8ebf25099 Input: iforce - invert valid length check when fetching device IDs
syzbot is reporting uninitialized value at iforce_init_device() [1], for
commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer
when fetching device IDs") is checking that valid length is shorter than
bytes to read. Since iforce_get_id_packet() stores valid length when
returning 0, the caller needs to check that valid length is longer than or
equals to bytes to read.

c7e37cc624 Input: goodix - try resetting the controller when no config is set
On ACPI systems (irq_pin_access_method == IRQ_PIN_ACCESS_ACPI_*) the driver
does not reset the controller at probe time, because sometimes the system
firmware loads a config and resetting might loose this config.

On the Nanote UMPC-01 device OTOH the config is in flash of the controller,
the controller needs a reset to load this; and the system firmware does not
reset the controller on a cold boot.

To fix the Nanote UMPC-01 touchscreen not working on a cold boot, try
resetting the controller and then re-reading the config when encountering
a config with 0 width/height/max_touch_num value and the controller has
not already been reset by goodix_ts_probe().

This should be safe to do in general because normally we should never
encounter a config with 0 width/height/max_touch_num. Doing this in
general not only avoids the need for a DMI quirk, but also might help
other systems.
