It\nprovides a set of chars devices, one per PPS source, which can be used to\nget the time signal.  The RFC\u0027s functions can be implemented by accessing\nto these char devices.\n\nSigned-off-by: Rodolfo Giometti \u003cgiometti@linux.it\u003e\nCc: David Woodhouse \u003cdwmw2@infradead.org\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nCc: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nAcked-by: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@googlemail.com\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Roman Zippel \u003czippel@linux-m68k.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
