I'm not convinced that the sysfs approach is actually the right interface here (I'm certainly not a fan of the gpio sysfs i/f), and I'd rather not be putting in unneeded stuff until the userspace i/f is hammered out.
Actually, thinking about it I cannot see what would be wrong with /dev/gpio0 & friends in the first place.
Using sysfs as swiss army knife for custom I/O does not seem like it would be long-term viable so thanks for this observation, and I think we need /dev/gpio* put on some mental roadmap somewhere.
Agreed. I don't want to be in the situation we are now with GPIO, where every time I look at the sysfs interface I shudder.
