Merge branch 'bnxt_en-ptp'
Michael Chan says:
====================
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.
