How to use the FT5216 capacitive touch screen of ILI9481 #578

I have the device tree configured and can be displayed. I don't know if FT5216 touch is supported, if so how can I use it

It's not directly supported by the driver edt-ft5x06 but it looks like many of the focaltech controllers use one of 2 firmwares: https://www.spinics.net/lists/linux-input/msg54001.html, so maybe it will work.

Apparently there's no maintainer for that driver so I suggest you ask on the mainlinglist.
