Kernel configuration for v6.1.4/ journalctl (dmesg)/ ACPIdump/lsmod

Overview: 
The touchscreen does not react on touch events.
Touchscreen display and touchpad are working.

Step to reproduce:
Open any UI page
Try to use touch on relevant UI controls (buttons etc.)

Result:
No reaction on screen touches

Expected result:
Reaction on touched control, same as when using the touch pad or connected mouse (which do work).

Build information:
The error happens with kernel version 6.1.4
After rebuilding with different kernel versions, it appears that it first fails with kernel 5.16

Additional builds:
The click mini l9w-b still works with kernel 5.10.y LTS and 5.15.y LTS.

Important remark:
Touchscreen still works fine with kernel 6.1.4 using  
- an HP x2 detachable 10-p0xx or
- a Lenovo yoga 520-14ikb

So it could be a hardware dependent issue

Could you please upload a dmesg from a working kernel, as that should tell us which driver is at fault.

I added output from a "journalctl -p 7" as it is part of what our UI log can produce quickly.
Comment 5 The Linux kernel's regression tracker (Thorsten Leemhuis) 2023-02-17 12:31:24 UTC
is this still happening with the latest kernels? e.g. ideally try 6.2-rc8 or later.
Comment 6 Gé Koerkamp 2023-02-20 23:15:10 UTC
I will try with 6.2-rc8, it was not working yet with 6.2-rc2 when I tried a few weeks ago.
Comment 7 Gé Koerkamp 2023-02-21 17:35:49 UTC
It was tested today with 6.2.0, nothing changed, still failing.
Comment 8 Gé Koerkamp 2023-02-28 12:18:24 UTC
Additionall, I searched for reported SIS0817 issues, yet I did not find any.
Perhaps it is a hint.
