Commit Message
From: Pandith N <pandith.n@intel.com>
PPS documentation has a generalized section for generators. Update the
section so any new generator documentation can be appended.

It should be v2 with a changelog.

Applied, thanks.

Sometimes one needs to be able not only to catch PPS signals but to produce
them also. For example, running a distributed simulation, which requires
-computers' clock to be synchronized very tightly. One way to do this is to
-invent some complicated hardware solutions but it may be neither necessary
-nor affordable. The cheap way is to load a PPS generator on one of the
-computers (master) and PPS clients on others (slaves), and use very simple
-cables to deliver signals using parallel ports, for example.
