Subject: [PATCH v5 0/1] net: fec: ptp: avoid register access when ipg clock is disabled

V5:
  Unlock the mutex when ptp clk is off in fec_ptp_settime() function.

V4:
* Init the ptp_clk_on flag to false in .probe(), and add mutex to protect the ptp clock
  status.

V3:
* Suggest from Richard Cochran, time_keep work is COMPLETELY INDEPENDENT from time stamping,
  let it always run. In .fec_ptp_gettime() function will return an error when ptp physical
  clock is disabled.

V2:
* As Richard Cochran's suggestion, use schedule_delayed_work instead of period timer.
* Stop delayed work before ipg clock disable like suspend, ethx close.
