Also: this driver does not register a GPIO provider - rather it's a GPIO consumer. For what you're trying to achieve: have you tried using libgpiod and controlling the lines from user-space? If that's too slow, then I'd say this driver should go somewhere else. Maybe you'd need a whole new protocol sub-system for that. In any case - this subsystem is not the right place. Bartosz [snip]
