Input: i8042 - fix leaking of platform device on module removal

2022-11-25T16:42:21+00:00

[ Upstream commit 81cd7e8489278d28794e7b272950c3e00c344e44 ] 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.

Input: i8042 - enable deferred probe quirk for ASUS UM325UA

2022-01-05T11:37:43+00:00

[ Upstream commit 44ee250aeeabb28b52a10397ac17ffb8bfe94839 ] The ASUS UM325UA suffers from the same issue as the ASUS UX425UA, which is a very similar laptop. The i8042 device is not usable immediately after boot and fails to initialize, requiring a deferred retry. Enable the deferred probe quirk for the UM325UA.

Input: i8042 - add deferred probe support

2022-01-05T11:37:43+00:00

[ Upstream commit 9222ba68c3f4065f6364b99cc641b6b019ef2d42 ] We've got a bug report about the non-working keyboard on ASUS ZenBook UX425UA. It seems that the PS/2 device isn't ready immediately at boot but takes some seconds to get ready. Until now, the only workaround is to defer the probe, but it's available only when the driver is a module. However, many distros, including openSUSE as in the original report, build the PS/2 input drivers into kernel, hence it won't work easily. This patch adds the support for the deferred probe for i8042 stuff as a workaround of the problem above. When the deferred probe mode is enabled and the device couldn't be probed, it'll be repeated with the standard deferred probe mechanism. The deferred probe mode is enabled either via the new option i8042.probe_defer or via the quirk table entry. As of this patch, the quirk table contains only ASUS ZenBook UX425UA. The deferred probe part is based on Fabio's initial work.

Input: i8042 - Add quirk for Fujitsu Lifebook T725

commit 16e28abb7290c4ca3b3a0f333ba067f34bb18c86 upstream. Fujitsu Lifebook T725 laptop requires, like a few other similar models, the nomux and notimeout options to probe the touchpad properly. This patch adds the corresponding quirk entries.

Input: i8042 - add ASUS Zenbook Flip to noselftest list

2021-03-04T09:26:41+00:00

commit b5d6e7ab7fe7d186878142e9fc1a05e4c3b65eb9 upstream. After commit 77b425399f6d ("Input: i8042 - use chassis info to skip selftest on Asus laptops"), all modern Asus laptops have the i8042 selftest disabled. It has done by using chassys type "10" (laptop). The Asus Zenbook Flip suffers from similar suspend/resume issues, but it _sometimes_ work and sometimes it doesn't. Setting noselftest makes it work reliably. In this case, we need to add chassis type "31" (convertible) in order to avoid selftest in this device.

Avoid AUX loopback on this touchpad as well, thus input subsystem will be able to recognize a Synaptics touchpad in the AUX port.
