Subject: [PATCH net-next v2 0/9] Support external snapshots on dwmac1000

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
