Support for edt-ft5x06

[panli]

Dear all,

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?

best regards

Pan

Hi Pan

FT5X is supported on some third party boards, for example imx6qdl-sabrelite.dtsi

linux-imx6/imx6qdl-sabrelite.dtsi at boundary-imx_4.9.x_2.0.0_ga · boundarydevices/linux-imx6 · GitH... 

linux-imx6/imx6ul-tx6ul.dtsi at boundary-imx_4.9.x_2.0.0_ga · boundarydevices/linux-imx6 · GitHub 

Sabrelite: New FT5x06 touch screen and swapped Y (input_set_abs_params) 

[RFC,1/3] ARM: dts: imx7d: add imx7d-phyboard-zeta - Patchwork 

Best regards
