That's probably one of these commits:
563558b2c735: pps: add parallel port PPS signal generator
46b402a0e5e4: pps: add parallel port PPS signal generator
a10203c691ea: pps: add parallel port PPS client
Plus CONFIG_PPS_CLIENT_PARPORT=y.
This feature seems rather untested - this is a plain whitebox PC with a parallel
port.
Btw., why does 46b402a0e5e4 and 563558b2c735 have the same title?
Thanks,
Ingo
