I had a short look at your driver and it looks to me as if all it does is
expose the raw registers as sysfs attributes. So I think one thing you first
have to do is to figure out a generic interface for the device class. How does
a application usually use these kinds of devices, how can the interface be
abstracted, so it applies to a wider range of devices of this class and not
only to this one specific device.
