Hello Linux kernel input team,
On the 2020 Clevo "NL4x_NL5xLU" computer, the touchpad is not detected
correctly by default. I mean I could use touchpad single gestures but
not multi-touch gestures.
Adding "pci=nocrs" boot parameter solves the problem, details below.
This issue has been reported few months ago by another users on Ubuntu
Launchpad, see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904052
I tried on Debian Sid with kernel 5.8, 5.9, 5.10 and 5.11.0-rc4
(compiled two days ago) and the result is still the same.
When looking at "/proc/bus/input/devices" I don't see my touchpad but I
only see:

After adding the boot parameter "pci=nocrs" via grub I see in addition
two new devices:

In "The kernel's command-line parameters", it is requested to report a
bug if "pci=nocrs" is needed, here it is.
What can I do to help you making this touchpad working by default with
the Linux kernel?
(I don't know a lot about hardware and Linux kernel related stuff)
Thanks in advance.
