      ====================
      net: mscc: PTP Hardware Clock (PHC) support
      
      This series introduces the PTP Hardware Clock (PHC) support to the Mscc
      Ocelot switch driver. In order to make use of this, a new register bank
      is added and described in the device tree, as well as a new interrupt.
      The use this bank and interrupt was made optional in the driver for dt
      compatibility reasons.
      
      Thanks!
      Antoine
      
      Since v5:
        - Made sure both the PTP interrupt and register bank were available to
          enable supporting h/w timestamping.
        - Added a check after a kzalloc.
        - Add Reviewed-by tags from Andrew.
      
      Since v4:
        - Added SKBTX_IN_PROGRESS.
        - Fixed two xmas trees.
        - Rework the loop condition in ocelot_ptp_rdy_irq_handler.
      
      Since v3:
        - Fixed a spin_unlock_irqrestore issue.
      
      Since v2:
        - Prevented from a possible infinite loop when reading the h/w
          timestamps.
        - s/GFP_KERNEL/GFP_ATOMIC/ in the Tx path.
        - Set rx_filter to HWTSTAMP_FILTER_PTP_V2_EVENT at probe.
        - Fixed s/w timestamping dependencies.
        - Added Paul Burton's Acked-by on patches 2 and 4.
      
      Since v1:
        - Used list_for_each_safe() in ocelot_deinit().
        - Fixed a memory leak in ocelot_deinit() by calling
          dev_kfree_skb_any().
        - Fixed a locking issue in get_hwtimestamp().
        - Handled the NULL case of ptp_clock_register().
        - Added comments on optional dt properties.
