The current implementation on the Goodix driver requires the two optional GPIOs (RESET and INT) to be provided.
However, it is possible to designs the RESET line pulled-up and only provide the INT line. Such designs do not work with the current implementation. The patch attached allows for designs that only provide the INT line to have a functional touch on the default I2C address, even though some functionality like the sleep mode will not be available. This has been tested on v4.20 with a gt911 based touch panel design that only provides the INT line.
