Subject: [PATCH v2 0/4] net: fec: ptp: Add FEC PPS ouput support.

These patches use hardeware adjustment to ptp timer and add pps ouput
support.

Change from v1 to v2:
	- Fix the potential 32-bit multiplication overflow issue.
	- Optimize the hareware adjustment code to improve efficiency as Richard suggested
	- Use ptp PTP_PIN_SET/GETFUNC interface to set PPS channel not device tree
	  and add PTP_PF_PPS enumeration
	- Modify comments style
	
Luwei Zhou (4):
  net: fec: ptp: Use the 31-bit ptp timer.
  net: fec: ptp: Use hardware algorithm to adjust PTP counter.
  ptp: Add PTP_PF_PPS enumeration to ptp_pin_function.
  net: fec: ptp: Enalbe PPS ouput based on ptp clock
