GT9XX from is a capacitive touch controller series supporting:
CONFIG_TOUCHSCREEN_GT9XX=y
The keyword refers to an embedded hardware configuration consisting of a Goodix GT9xx series capacitive touch controller paired with a display resolution configured near the standard 7-inch to 9-inch 1024x600 or 1085x600 widescreen aspect ratio . This specific combination is widely utilized in aftermarket Android car head units (multimedia players), single-board computer (SBC) touchscreen panels, and industrial Human-Machine Interfaces (HMIs).
from a manufacturer?
Because the GT9XX is not a complete display assembly itself but rather a sensor attached to the glass, it requires specific kernel-level drivers to function on platforms like Linux and Android. Linux Kernel Support
