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. ==================== Signed-off-by: David S. Miller --- a1b05634e1f0ab11a37906557c8e8eb2aeece222
