Subject: [PATCH v4 0/3] net: mvpp2: tai: add extts support
Date: Sun, 30 Apr 2023 20:06:53 +0300 [thread overview]
Message-ID: <20230430170656.137549-1-shmuel.h@siklu.com> (raw)
This patch series adds support for PTP event capture on the Aramda
80x0/70x0. This feature is mainly used by tools linux ts2phc(3) in order
to synchronize a timestamping unit (like the mvpp2's TAI) and a system
DPLL on the same PCB.
The patch series includes 3 patches: the second one implements the
actual extts function.
Changes in v2:
* Fixed a deadlock in the poll worker.
* Removed tabs from comments.
Changes in v3:
* Added more explanation about the change in behavior in mvpp22_tai_start.
* Explain the reason for choosing 95ms as a polling rate.
Changes in v4:
* Add additional lock for the polling worker reference count.
