Touchscreen not working

Touchscreen not working

Hey,

I'm trying make an image that will just bootup, start an X server (or maybe potentially wayland later), and our program, which is basically a webserver and a gtk webview. This all works. But the problem is, that this should run on a MS Surface Go 2, and the touch screen isn't working. When I boot an Ubuntu installer image, the touchscreen is working in the installer, it doesn't even require the surface specific patches.

I added about every touchscreen driver in the kernel, and experimented a lot with other kernel options, but nothing seems to work. I also installed libevdev. What am I missing?

This is my current kernel configuration fragment:

I'm using Kirkstone and the Intel-BSP, kernelversion is 5.15.

I'm also getting this warning during baking:
