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.
