It includes a compatible string for one display (more can be added in the future). The YX350HV15 panel[1] is found in the Adafruit PiTFT 3.5" Touch Screen for Raspberry Pi. [1] https://learn.adafruit.com/adafruit-pitft-3-dot-5-touch-screen-for-raspberry-pi/downloads This binding is closely modeled after the ili9341 binding, for a similar product from adafruit. The primary difference is that the hx8367d doesn't have a reset line that I can find in the schematics.
