The ptp clock operations will be used in dpaa2-eth driver. For example, supporting one step timestamping needs to write current time to hardware frame annotation before sending and then hardware inserts the delay time on frame during sending. So in driver, at least clock gettime operation will be needed to make sure right time is written to hardware frame annotation for one step timestamping.
