Goodix devices can be configured by writing custom data to the device at init. The configuration data is read with request_firmware from "goodix_<id>_cfg.bin", where <id> is the product id read from the device (e.g.: goodix_911_cfg.bin for Goodix GT911, goodix_9271_cfg.bin for GT9271). The configuration information has a specific format described in the Goodix datasheet. It includes X/Y resolution, maximum supported touch points, interrupt flags, various sesitivity factors and settings for advanced
sensitivity.
