Why do you leave the device in reset state? I think you wanted these reverted.
I imagine practical systems aren't using the inversion that gpiolib can do via the bindings, this is already the case for the other drivers sharing the binding. TBH the use for things like reset lines has always seemed like it causes more confusion and error than it solves.
