Subject: [PATCH net-next 06/18] ptp: ocp: Add third timestamper
Date: Tue, 14 Sep 2021 19:16:24 -0700	[thread overview]
Message-ID: <20210915021636.153754-7-jonathan.lemon@gmail.com> (raw)
In-Reply-To: <20210915021636.153754-1-jonathan.lemon@gmail.com>

The firmware may provide a third signal timestamper, so make it
available for use.
