The 4 wire touchscreen support is provided by using on module circuitry
mainly comprising of FET's and leveraging the GPIOs and on chip ADC of
the Vybrid SoC.
This is specific to our Colibri Vybrid VF50 module and not the Freescale
IP. While I guess one could certainly use the driver for their own needs
if one were to replicate a similar circuitry and change the DT properties
concerning GPIO and ADC's as per their own board, as of now this is only
use on our Toradex VF50 modules and was done by us specifically to provide
touchscreen support for VF50.
