Thanks! (The merge request and this report are related.)

Some additional information: I (finally) managed to (cross-)build 
a Debian kernel package and test this:
 * the battery gauge is working!
 * the usb-c port gets its FUSB302 driver, but hits an error later:
[    8.656555] OF: graph: no port node found in /i2c@ff3d0000/fusb30x@22
   (This may be related to this patch to the DTD:
  https://patchwork.kernel.org/project/linux-rockchip/patch/20200924063042.41545-1-jhp@endlessos.org/
   which made the monitor work, or possibly another missing driver.)
 * pulseaudio starts correctly (unlike before), but no sound (note: the 
   internal switch controlling the audio jack is set in "serial port" 
   mode; I'm not sure whether this affects the speakers, I will try 
   flipping the switch later).

So this is clearly an improvement (especially the battery gauge), but not 
a complete solution.

Best regards,
