- As Greg already mentioned, you need to implement gpio support using gpiolib, not a custom sysfs interfaceI don't have time to look closer at the architectural bits until next week I'm afraid, but perhaps you could start with the above.
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? -- With Best Regards, Peter Hung -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
