This patch series contains driver implementation for TI Common Platform
Time Sync (CPTS) driver for PTP packet timestamping.
CPTS is found in following TI SoC.
* AM335X - http://www.ti.com/litv/pdf/spruh73c
* DM814X - http://www.ti.com/litv/pdf/sprugz8
The Common Platform Time Sync (CPTS) module is used to facilitate host
control of time sync operations. It enables compliance with the IEEE 1588-2008
standard for a precision clock synchronization protocol
This patch series is tested over vanilla kernel with the below patches
http://marc.info/?l=linux-arm-kernel&m=13503286372390...
Tested both L2 and L4 PTP packet timestamping
Mugunthan V N (6):
drivers: net: ethernet: cpsw: add support for CPSW register offset
changes in different IP version
drivers: net: ethernet: davinci_cpdma: add clear api for statistics
interrupt
drivers: net: ethernet: cpsw: add multicast address to ALE table
ptp: add api to get ptp seq id and event type from skb
drivers: net: ethernet: cpts: implement cpts hardware clock
drivers: net: ethernet: cpsw: implement timestamping capabilities in
cpsw
