Hey.
I have a beer machine running on a A13-SOM-512 board. I'm trying to install a newer linux version on it, and it seems to go fine, but I'm having a lot of trouble getting the capacitive touch panel to work (the display itself seems to work just fine). The touch panel is using a goodix gt911 chip.

The old installation uses a "script.fex" file, and I'm trying to make the new installation work with the dtb tree.
I'm editing the dts file directly, since I had trouble getting overlays to work.
I'm attaching the dts file below.


If I understand correctly, I should be able to get some data using "cat /dev/input/event0", and touching the screen - but I so far I only get a "mice" in /dev/input.
I've compiled the kernel using the instructions:

git clone https://github.com/olimex/build -b olimex-dev
cd build
touch .ignore_changes
./compile.sh BRANCH=next BOARD=olimex-som-a13 KERNEL_ONLY=no KERNEL_CONFIGURE=yes CLEAN_LEVEL="make,debs,alldebs,images" RELEASE=stretch BUILD_KSRC=no NO_APT_CACHER=yes BUILD_DESKTOP=no

and enabling the goodix touch panel driver as a module.
I can load the module fine without any errors, but I just don't get any event0...

Please help.

I'm attaching various log below
Note - in the script.fex, the pin for the interrupt is shown as PG12 - but tracing the circuit board that teh A13-SOM is connected to, the actual pin that the panel interrupt is connected to, is PG11. Reset is still PC3, and scl and sda is PB17/18.
