Subject: [PATCH net-next v4 0/9] Support external snapshots on dwmac1000

Hi,

This is v4 on the series to support external snapshots on dwmac1000.

The main change since v3 is the move of the fifo flush wait in the
ptp_clock_info enable() function within the mutex that protects the ptp
registers. Thanks Jakub and Paolo for spotting this.

This series also aggregates Daniel's reviews, except for the patch 4
which was modified since then.

This series is another take on the previous work [1] done by
Alexis Lothoré, that fixes the support for external snapshots
timestamping in GMAC3-based devices.

Details on why this is needed are mentionned on the cover [2] from V1.

Thanks Alexis for laying the groundwork for this,

Best regards,

Maxime
