Subject: [PATCH v2 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.
