Subject: [PATCH v3 net-next 00/15] Add NETC Timer PTP driver and add PTP support for i.MX95

This series adds NETC Timer PTP clock driver, which supports precise
periodic pulse, time capture on external pulse and PTP synchronization.
It also adds PTP support to the enetc v4 driver for i.MX95 and optimizes
the PTP-related code in the enetc driver.
