Thanks for your advices, I'll try to improve it again. But I had something need to clarify.
1. The sysfs interface of the driver provide "limited output pin" control. only support output 0/1, not support input mode. Should I implement it as gpiolib?
2. If it still recommends to implement with gpiolib, Could I implement it and preserve the sysfs interface for legacy?
