FocalTech FT5406EE8 and ConnectCore6

There are more than 100 “Digi ConnectCore 6 version 1” model devices. We want to operate with FocalTech FT5406EE8 touch screen. But it is not working right now. I activated driver via menuconfig, i2c is activated but not working. I could not apply Device Tree settings because I did not know how to configure it. Do you have any idea about this problem?

There are 2 different versions of the driver for FocalTech. The one that already exists in the kernel is EDT driver. The DT tree configuration example for it is here:
