I have a touchscreen that communicates by serial interface to Linux 4.14. I have the serial comm getting into the NXP chip. How do I get the kernel to recognize this serial traffic as a touchscreen?
I am not seeing any driver associated with this touchscreen so I’m thinking it is something already in the kernel.
I have the devicetree configured for the serial Rx/Tx lines. How do I tell the kernel this is the touchscreen? (What am I missing?)
