Subject: [PATCH v8 net-next 0/3] Add PTP support for Octeontx2

From: Subbaraya Sundeep <sundeep.lkml@...il.com>

Hi,

This patchset adds PTP support for Octeontx2 platform.
PTP is an independent coprocessor block from which
CGX block fetches timestamp and prepends it to the
packet before sending to NIX block. Patches are as
follows:

Patch 1: Patch to enable/disable packet timstamping
         in CGX upon mailbox request. It also adjusts
         packet parser (NPC) for the 8 bytes timestamp
         appearing before the packet.

Patch 2: Patch adding PTP pci driver which configures
         the PTP block and hooks up to RVU AF driver.
         It also exposes a mailbox call to adjust PTP
         hardware clock.

Patch 3: Patch adding PTP clock driver for PF netdev.

v8:
 Added missing header file reported by kernel test robot
 in patch 2
v7:
 As per Jesse Brandeburg comments:
 Simplified functions in patch 1
 Replaced magic numbers with macros
 Added Copyrights
 Added code comments wherever required
 Modified commit description of patch 2
v6:
 Resent after net-next is open
v5:
 As suggested by David separated the fix (adding rtnl lock/unlock)
 and submitted to net.
 https://www.spinics.net/lists/netdev/msg669617.html
v4:
 Added rtnl_lock/unlock in otx2_reset to protect against
 network stack ndo_open and close calls
 Added NULL check after ptp_clock_register in otx2_ptp.c
v3:
 Fixed sparse error in otx2_txrx.c
 Removed static inlines in otx2_txrx.c
v2:
 Fixed kernel build robot reported error by
 adding timecounter.h to otx2_common.h
