For the user API, using a file descriptor is fine.

I am referring to the PPS driver itself. It should just use struct 
pps_state. A PPS driver may register a device file which can be accessed 
by the user API. Providing a device file should be optional to be able 
to use PPS in applications which do not use a filesystem at all.
