Input: i8042 - add Fujitsu Lifebook U728 to i8042 quirk table

2024-03-01T12:34:53+00:00

[ Upstream commit 4255447ad34c5c3785fcdcf76cfa0271d6e5ed39 ] Another Fujitsu-related patch. In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728 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 (04F3:3092) not working at all. So this notebook uses a hid-over-i2c touchpad which is managed by the i2c_designware input driver. Since you can't find a PS/2 mouse port on this computer and you can't connect a PS/2 mouse to it even with an official port replicator I think it's safe to not use the PS/2 mouse port at all.

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

2024-02-16T18:10:55+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 Signed-off-by: Werner Sembach Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20231205163602.16106-1-wse@tuxedocomputers.com Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

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

2024-01-20T10:51:44+00:00

[ Upstream commit 335fe00319e030d481a54d5e0e68d50c5e672c0e ] 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.

Pull input fixes from Dmitry Torokhov: - a reworked way for handling reset delay on SMBus-connected Synaptics touchpads (the original one, while being correct, uncovered an old bug in fallback to PS/2 code that was fixed separately; the new one however avoids having delay in serio port "fast" resume, and instead has the wait in the RMI4 code) - a fix for potential crashes when devices with Elan controllers (and Synaptics) fall back to PS/2 code. Can't be hit without the original patch above, but still good to have it fixed - a couple new device IDs in xpad Xbox driver - another quirk for Goodix driver to deal with stuff vendors put in ACPI tables - a fix for use-after-free on disconnect for powermate driver - a quirk to not initialize PS/2 mouse port on Fujitsu Lifebook E5411 laptop as it makes keyboard not usable and the device uses hid-over-i2c touchpad anyways * tag 'input-for-v6.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: powermate - fix use-after-free in powermate_config_complete Input: xpad - add PXN V900 support Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsport Input: psmouse - fix fast_reconnect function for PS/2 mode Revert "Input: psmouse - add delay when deactivating for SMBus mode" Input: goodix - ensure int GPIO is in input for gpio_count == 1 && gpio_int_idx == 0 case Input: i8042 - add Fujitsu Lifebook E5411 to i8042 quirk table Input: xpad - add HyperX Clutch Gladiate Support

tty: use u8 for flags

This makes all those 'char's an explicit 'u8'. This is part of the continuing unification of chars and flags to be consistent u8. This approaches tty_port_default_receive_buf().
