Input: atkbd - skip ATKBD_CMD_SETLEDS when skipping ATKBD_CMD_GETID

2024-02-16T18:14:29+00:00

commit 683cd8259a9b883a51973511f860976db2550a6e upstream.

After commit 936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in
translated mode") the keyboard on Dell XPS 13 9350 / 9360 / 9370 models
has stopped working after a suspend/resume.

The problem appears to be that atkbd_probe() fails when called
from atkbd_reconnect() on resume, which on systems where
ATKBD_CMD_GETID is skipped can only happen by ATKBD_CMD_SETLEDS
failing. ATKBD_CMD_SETLEDS failing because ATKBD_CMD_GETID was
skipped is weird, but apparently that is what is happening.

Fix this by also skipping ATKBD_CMD_SETLEDS when skipping
ATKBD_CMD_GETID.

Input: i8042 - fix strange behavior of touchpad on Clevo NS70PU

2024-02-16T18:14:29+00:00

commit a60e6c3918d20848906ffcdfcf72ca6a8cfbcf2e upstream.

When closing the laptop lid with an external screen connected, the mouse
pointer has a constant movement to the lower right corner. Opening the
lid again stops this movement, but after that the touchpad does no longer
register clicks.

The touchpad is connected both via i2c-hid and PS/2, the predecessor of
this device (NS70MU) has the same layout in this regard and also strange
behaviour caused by the psmouse and the i2c-hid driver fighting over
touchpad control. This fix is reusing the same workaround by just
disabling the PS/2 aux port, that is only used by the touchpad, to give the
i2c-hid driver the lone control over the touchpad.

v2: Rebased on current master

Input: atkbd - use ab83 as id when skipping the getid command

2024-01-25T23:45:09+00:00

commit 58f65f9db7e0de366a5a115c2e2c0703858bba69 upstream.

Barnabás reported that the change to skip the getid command
when the controller is in translated mode on laptops caused
the Version field of his "AT Translated Set 2 keyboard"
input device to change from ab83 to abba, breaking a custom
hwdb entry for this keyboard.

Use the standard ab83 id for keyboards when getid is skipped
(rather then that getid fails) to avoid reporting a different
Version to userspace then before skipping the getid.

Merge tag 'input-for-v6.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - a quirk to AT keyboard driver to skip issuing "GET ID" command when
   8042 is in translated mode and the device is a laptop/portable,
   because the "GET ID" command makes a bunch of recent laptops unhappy

 - a quirk to i8042 to disable multiplexed mode on Acer P459-G2-M which
   causes issues on resume

 - psmouse will activate native RMI4 protocol support for touchpad on
   ThinkPad L14 G1

 - addition of Razer Wolverine V2 ID to xpad gamepad driver

 - mapping for airplane mode button in soc_button_array driver for
   TUXEDO laptops

 - improved error handling in ipaq-micro-keys driver

 - amimouse being prepared for platform remove callback returning void

Input: soc_button_array - add mapping for airplane mode button

2023-12-23T07:34:06+00:00

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.

Check the return value of i2c_add_adapter. Static analysis revealed that
the function did not properly handle potential failures of
i2c_add_adapter, which could lead to partial initialization of the I2C
adapter and unstable operation.

Input: amimouse - convert to platform remove callback returning void

2023-12-01T23:36:18+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Input: i8042 - add nomux quirk for Acer P459-G2-M

2023-11-30T20:03:27+00:00

After the laptop lid is opened, and the device resumes from S3 deep
sleep, if the user presses a keyboard key while the screen is still black,
the mouse and keyboard become unusable.

Enabling this quirk prevents this behavior from occurring.

Input: atkbd - skip ATKBD_CMD_GETID in translated mode

2023-11-26T02:47:21+00:00

There have been multiple reports of keyboard issues on recent laptop models
which can be worked around by setting i8042.dumbkbd, with the downside
being this breaks the capslock LED.

It seems that these issues are caused by recent laptops getting confused by
ATKBD_CMD_GETID. Rather then adding and endless growing list of quirks for
this, just skip ATKBD_CMD_GETID alltogether on laptops in translated mode.

The main goal of sending ATKBD_CMD_GETID is to skip binding to ps/2
mice/touchpads and those are never used in translated mode.

Examples of laptop models which benefit from skipping ATKBD_CMD_GETID:

* "HP Laptop 15s-fq2xxx", "HP laptop 15s-fq4xxx" and "HP Laptop 15-dy2xxx"
  models the kbd stops working for the first 2 - 5 minutes after boot
  (waiting for EC watchdog reset?)

* On "HP Spectre x360 13-aw2xxx" atkbd fails to probe the keyboard

* At least 9 different Lenovo models have issues with ATKBD_CMD_GETID, see:
  https://github.com/yescallop/atkbd-nogetid

This has been tested on:

1. A MSI B550M PRO-VDH WIFI desktop, where the i8042 controller is not
   in translated mode when no keyboard is plugged in and with a ps/2 kbd
   a "AT Translated Set 2 keyboard" /dev/input/event# node shows up

2. A Lenovo ThinkPad X1 Yoga gen 8 (always has a translated set 2 keyboard)
