commit aed3716db7fff74919cc5775ca3a80c8bb246489 upstream. The device occasionally wakes up from suspend with missing input on the internal keyboard and the following suspend attempt results in an instant wake-up. The quirks fix both issues for this device.

commit d85862ccca452eeb19329e9f4f9a6ce1d1e53561 upstream. Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. We could not activly retest these devices because we no longer have them in our archive, but based on the other old Clevo barebones we tested where the new quirk had the same or a better behaviour I think it would be good to apply it on these too.

2024-08-29Input: i8042 - add forcenorestore quirk to leave controller untouched even on s3Werner Sembach2-6/+14
commit 3d765ae2daccc570b3f4fbcb57eb321b12cdded2 upstream. On s3 resume the i8042 driver tries to restore the controller to a known state by reinitializing things, however this can confuse the controller with different effects. Mostly occasionally unresponsive keyboards after resume. These issues do not rise on s0ix resume as here the controller is assumed to preserved its state from before suspend. This patch adds a quirk for devices where the reinitialization on s3 resume is not needed and might be harmful as described above. It does this by using the s0ix resume code path at selected locations. This new quirk goes beyond what the preexisting reset=never quirk does, which only skips some reinitialization steps.

[ 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.

2024-02-16Input: i8042 - fix strange behavior of touchpad on Clevo NS70PUWerner Sembach1-0/+6
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 <wse@tuxedocomputers.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20231205163602.16106-1-wse@tuxedocomputers.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-07-13Input: i8042 - add quirk for TUXEDO Gemini 17 Gen1/Clevo PD70PNWerner Sembach1-0/+7
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.

2023-05-18Input: libps2 - do not discard non-ack bytes when controlling LEDsDmitry Torokhov1-4/+32
Upon receiving a PS/2 command the device and controller are supposed to stop sending normal data (scancodes or movement packets) and instead immediately start delivering ACK/NAK and command response. Unfortunately often EC has an output buffer which may contain latched data by the time the EC receives a command from the host. The kernel used to ignore such data, but that may cause "stuck" keys if the data dropped happens to be a break code or a part of a break code. This occasionally happens, for example, on Chromebooks when the kernel tries to toggle CapsLock LED on a keyboard while user releases Alt+Search keyboard shortcut. Fix this by passing the first non-ACK byte to the normal handler for a handful of PS/2 commands that are expected to be used during normal device operation (as opposed to probe/configuration time).

2023-03-24Input: i8042 - add TUXEDO devices to i8042 quirk tables for partial fixWerner Sembach1-0/+28
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.

There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort.
