Subject: [PATCH net-next 00/12] Add NETC Timer PTP driver and add PTP support for ENETC v4

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, and also optimizes the
PTP-related code in the enetc driver.

F.S. Peng (1):
  ptp: netc: add external trigger stamp support

Wei Fang (11):
  dt-bindings: ptp: add bindings for NETC Timer
  ptp: netc: add NETC Timer PTP driver support
  ptp: netc: add PPS support
  ptp: netc: add periodic pulse output support
  ptp: netc: add debugfs support to loop back pulse signal
  MAINTAINERS: add NETC Timer PTP clock driver section
  net: enetc: save the parsed information of PTP packet to skb->cb
  net: enetc: Add enetc_update_ptp_sync_msg() to process PTP sync packet
  net: enetc: remove unnecessary CONFIG_FSL_ENETC_PTP_CLOCK check
  net: enetc: add PTP synchronization support for ENETC v4
  net: enetc: don't update sync packet checksum if checksum offload is
    used
