Touch controller (SSD2543QN10) driver for iMX8MM

Bhargava — Wed, 22 Sep 2021 04:52:24 GMT

Hi,

We have an LCD display for which the touch controller used is SSD2543QN10. We could not find any available driver for the kernel v5.4 however we did find a reference driver for kernel v4.4.

https://github.com/patrickhwood/linux/blob/kk4.4.2_1.0.0-ga-uib/drivers/input/touchscreen/ssd2543.c

But when we tried to port the reference driver to our kernel we found lot of dependencies missing.

Please provide pointers to find the correct driver and its implementation which will be a great help.

SoM: iMX8MM

Yocto Dunfell

Regards,

Bhargava

Hi Bhargava

this device was not used in NXP BSPs, in general one can look at linux general documentation and examples

https://www.kernel.org/doc/html/v4.16/media/uapi/v4l/dev-touch.html

https://boundarydevices.com/configuring-i-mx6-machines-different-screens-nitrogen6x-sabre-lite/

and proceed (if necessary) with help of https://contact.nxp.com/new-prof-svcs-sw-tech

Best regards
