Subject: [PATCH v2 0/4] net: fec: ptp: Add FEC PPS ouput support.
Date: Sun, 28 Sep 2014 12:20:07 +0800 [thread overview]
Message-ID: <1411878011-21767-1-git-send-email-b45643@freescale.com> (raw)
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
