Subject: [PATCH net-next v2 0/7] net: lan966x: Add PTP Hardward Clock support

Add support for PTP Hardware Clock (PHC) for lan966x. The switch supports
both PTP 1-step and 2-step modes.

v1->v2:
- fix commit messages
- reduce the scope of the lock ptp_lock inside the function
  lan966x_ptp_hwtstamp_set
- the rx timestamping is always enabled for all packages

Horatiu Vultur (7):
  dt-bindings: net: lan966x: Extend with the ptp interrupt
  net: lan966x: Add registers that are use for ptp functionality
  net: lan966x: Add support for ptp clocks
  net: lan966x: Implement SIOCSHWTSTAMP and SIOCGHWTSTAMP
  net: lan966x: Update extraction/injection for timestamping
  net: lan966x: Add support for ptp interrupts
  net: lan966x: Implement get_ts_info
