Looking back, I now recall that the series lets the HW embed the time

The application does join that group on the external (slave)
interface. I'll

So i did a quick test. If the application joins 224.0.1.129 on the
slave interface, the switch will pass the packets to the host and to
the application

I have not. Our usage has been focused on 802.1AS; the ptp4l settings we
use are the following:
transportSpecific0x1
ptp_dst_mac 01:80:C2:00:0

Yes, I ssh into the device via the external switch port interface.
Thanks,

Oops, I had "slaveOnly" set in my PC's configuration. So layer2 seems
to work as expected.

I now have a 88E6352 to test your series on. Unfortunately, it
doesn't really work. Here is what I did.

The driver should implement a cyclecounter/timecounter.

I assume ptp already has the core code to use pinctrl and Linux
standard GPIOs? What does the device tree binding look like? How do
you specify the GPIOs to use?
This patch series adds support for PTP timestamping through the DSA
framework, as well as an implementation for mv8e6xxx switches.
This implementation was targeted at a National Instruments platform
that uses the Marvell 88E6341 (Topaz). I've tried to enable support on
other Marvell switches where
