we have got a capacitive touchscreen display (ETMV570G0BDHU) which we would like to test with our Sabreboard MCIMX7SABRE. Because the default configuration in device tree file only support resistive touch, I disabled it and add our configuration for capacitive touch. The touch driver edt-ft5x06 was installed in linux kernel through CONFIG TOUCHSCREEN_EDT_FT5X06. The linux kernel was built with a yocto system. The kernel version is 4.12.
After booting, we saw that the driver is connected with the device. However, touch doesn't work. We didn't see any interrupt coming from display if we press on the screen.
Do you have any working example of device tree file for capacitive touch on this board?
