We have to number our GPIOs accordingly. Ideally the board.d scripts should look through sysfs to find the basenum (like cat "/sys/devices/platform/soc/2000000.i2c/ i2c-0/0-0076/gpio/gpiochip640/base"), but the problem is that this occurs before modules are loaded, meaning I2C and other runtime devices may be missing.
