No changes were made. 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.
