Yes, but please trim your replies next time. Scrolling through pages
of quoted headers and stale content in order to read one line is very
annoying.

Cadence GEM provides a 102 bit time counter with 48 bits for seconds,
30 bits for nsecs and 24 bits for sub-nsecs to control 1588 timestamping.
This patch does the following:
- Registers to ptp clock framework
- Timer initialization is done by writing time of day to the timer counter.
- ns increme
