Please describe your use case.

The PPS framework distinguishes between "clients" and "generators".
Clients receive PPS signals and generators produce them.

The correct place for this functionality would be in a new
"pps_gen_gpio.c" driver, similar to "pps_gen_parport.c". Then, it could
be used together with different PPS clients.
