   Dear Maintainer,   
      
   Could you enable Intel THC HID Support modules in the standard kernel to   
   support Lunar Lake Touch screen:   
   Digitizer Pen [0901]: Intel Corporation Lunar Lake-M Touch Host Controller #0   
   ID1 [8086:a848] (rev 10)   
      
   Current Trixie kernels doesn't have them enabled (both standard and one   
   from backports):   
      
   # grep CONFIG_INTEL_THC_HID /boot/config-6.16.3+deb13-amd64   
   # CONFIG_INTEL_THC_HID is not set   
      
   I have managed to rebuild the kernel with the following:   
   #   
   # Intel THC HID Support   
   #   
   CONFIG_INTEL_THC_HID=m   
   CONFIG_INTEL_QUICKSPI=m   
   CONFIG_INTEL_QUICKI2C=m   
   # end of Intel THC HID Support   
      
   and the touch screen started working with custom kernel.   
      
   Manny thanks
