pps: remove unreachable code

2011-03-23T00:44:17Z

Remove code enabled only when CONFIG_PREEMPT_RT is turned on because it is not used in the vanilla kernel. Signed-off-by: Alexander Gordeev Cc: john stultz Cc: Rodolfo Giometti Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

pps: claim parallel port exclusively

2011-01-26T00:50:00Z

Both pps_parport and pps_gen_parport are written in a way that they can't share a port with any other driver. This can result in locking up the process that loads modules or even the whole kernel if the modules are compiled in. Use PARPORT_FLAG_EXCL to indicate this.

pps: add parallel port PPS signal generator

2011-01-13T16:03:21Z

Add PPS signal generator which utilizes STROBE pin of a parallel port to send PPS signals. It uses parport abstraction layer and hrtimers to precisely control the signal. Signed-off-by: Alexander Gordeev Cc: Rodolfo Giometti Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
