Revert "Input: ioc3kbd - convert to platform remove callback returning void"

2024-09-04T11:17:45+00:00

This reverts commit 0096d223f78cb48db1ae8ae9fd56d702896ba8ae which is
commit 150e792dee9ca8416f3d375e48f2f4d7f701fc6b upstream.

It breaks the build and shouldn't be here, it was applied to make a
follow-up one apply easier.

Input: ioc3kbd - convert to platform remove callback returning void

2024-06-16T11:32:21+00:00

[ Upstream commit 150e792dee9ca8416f3d375e48f2f4d7f701fc6b ]

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 Fujitsu Lifebook U728 to i8042 quirk table

2024-03-01T12:16:45+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

2024-02-23T07:42:22+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: i8042 - add nomux quirk for Acer P459-G2-M

2024-01-25T22:37:37+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.

Input: i8042 - add Fujitsu Lifebook E5411 to i8042 quirk table

Input: i8042 - add quirk for TUXEDO Gemini 17 Gen1/Clevo PD70PN

2023-10-10T19:53:29+00:00

[ Upstream commit eb09074bdb05ffd6bfe77f8b4a41b76ef78c997b ]

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.

[ Upstream commit 8761b9b580d53162cca7868385069c0d4354c9e0 ]

Now i8042-x86ia64io.h is shared by X86 and IA64, but it can be shared
by more platforms (such as LoongArch) with ACPI firmware on which PNP
typed keyboard and mouse is configured in DSDT. So rename it to i8042-
acpipnpio.h.
