Subject: [PATCH 0/6] Add CPTS PTP driver support

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=135032863723906&w=2
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
