Thanks for your feedback and dmesg log.
It seems that the device for touch is disabled. You can get the binary devicetree file (.dtb) from the image you flashed either from the website or from the module using the UMS Feature. Once you got the binary file, then you need to extract this file to the souce using DTC Compiler. Afterwards you can change the sources and create again the binary file with enabled device for touch.
I attached the device-tree files where the touch device is already enabled. You can flash this to the module and check if touch interface is working.
Best regards,
Jaski
