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?
