Subject: [PATCH v1] Documentation: driver-api: pps: Update PPS generator documentation
From: Pandith N <pandith.n@...el.com>
PPS documentation has a generalized section for generators. Update the
section so any new generator documentation can be appended.

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.
