Subject: [net-next PATCH v2 0/4] Add PTP support for CN10K silicon
Date: Sat, 30 Jul 2022 17:27:54 +0530 [thread overview]
Message-ID: <20220730115758.16787-1-naveenm@marvell.com> (raw)
This patchset adds PTP support for CN10K silicon, specifically
to workaround few hardware issues and to add 1-step mode.
Patchset overview:
Patch #1 returns correct ptp timestamp in nanoseconds captured
when external timestamp event occurs.
Patch #2 adds 1-step mode support.
Patch #3 implements software workaround to generate PPS output properly.
Patch #4 provides a software workaround for the rollover register default
value, which causes ptp to return the wrong timestamp.
v2 changes:
no code changes, added PTP maintainer to CC list.
