Subject: [PATCH] Input: i8042 - add TUXEDO devices to i8042 quirk tables for
partial fix
References: bsc#1012628
Patch-mainline: 6.2.10
Git-commit: cbedf1a33970c9b825ae75b81fbd3e88e224a418
commit cbedf1a33970c9b825ae75b81fbd3e88e224a418 upstream.
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.
