Subject: [PATCH net-next v2 0/7] bnxt_en: Add hardware PTP timestamping support on 575XX devices

Add PTP RX and TX hardware timestamp support on 575XX devices.  These
devices use the two-step method to implement the IEEE-1588 timestamping
support.

v2: Add spinlock to serialize access to the timecounter.
    Use .do_aux_work() for the periodic timer reading and to get the TX
    timestamp from the firmware.
    Propagate error code from ptp_clock_register().
    Make the 64-bit timer access safe on 32-bit CPUs.
    Read PHC using direct register access.

Michael Chan (4):
  bnxt_en: Update firmware interface to 1.10.2.47
  bnxt_en: Get PTP hardware capability from firmware
  bnxt_en: Add PTP clock APIs, ioctls, and ethtool methods
  bnxt_en: Enable hardware PTP support

Pavan Chebbi (3):
  bnxt_en: Get the full 48-bit hardware timestamp periodically
  bnxt_en: Get the RX packet timestamp
  bnxt_en: Transmit and retrieve packet timestamps
