Hi,
This series is another take on the pervious 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.
This V2 addresses multiple issues found in V1 :
- The PTP_TCR register is configured from multiple places, as reported
by Alexis, so we need to make sure that the extts configuration
doesn't interfere with the hwtstamp configuration.
- The interrupt management in V1 was incomplete, as the interrupt
wasn't correctly acked.
- This series also makes so that we only enable the extts interrupt
when necessary.

Thanks Alexis for laying the groundwork for this,
Best regards,
Maxime
