i am trying to enable touch for the 8 inch display on your build, the display is from radxa, and after enabling the hadware configuration and enabling rock-5a-radxa-display-8hd from the menu, the display is working perfectly, but the touch isnt working, i was searching the official build for the touch related sources, the touch is controlled by godot GT911 driver IC, its using i2c for touch,
