The gpio_chip has this: struct gpio_chip { const char *label; struct device *dev; (...) const char *const *names; (...) If you want to help the users, provide string names for all the GPIO lines and suggest them to do code in userspace that use these names instead of GPIO numbers. Also the string names "gpio0", "gpio1" etc are much better than just using the Linux-specific numbers. So what about making a patch to drivers/gpio/gpio-dwapb.c that adds the .names property to its GPIO chip?
