Also ACPI, and this is a long standing binding so we can't change the ABI for DT. We could potentially use a refcounting mechanism provided by the GPIO core but we'd need to know when the refcount changes from 0 to 1 and back, we need to take other actions (inserting delays and generating notifications) when it does so I'm not sure how exciting it is to factor out the refcount. I think part of the decision making with the current design was that there was likely going to need to be some higher level stuff like that in the users so it wasn't clear that trying to abstract the reference count away in gpiolib was buying us much.
