[RFC 0/3] Add PPS generators

[Rodolfo Giometti]

PPS generators are special hardware which are able to produce PPS
(Pulse Per Second) signals.

This RFC patchset adds the class pps-gen to the kernel in order to get
feedback useful to produce a well-thought-out and well-defined
interface for these devices.

Rodolfo Giometti (3):
  drivers pps: add PPS generators support
  Documentation pps.rst: add PPS generators documentation
  Documentation ABI: add PPS generators documentaion
