  9. Description:
  10. Reading returns either '1' or '0'.
  11. '1' means that the clock in question is present.
  12. '0' means that the clock is missing.

  16. Description:
  17. Reading returns either '1' or '0'. '1' means that the
  18. pllY is locked.

  20. KernelVersion: 3.4.0

  22. Description:
  23. Writing '1' triggers the clock distribution synchronization
  24. functionality. All dividers are reset and the channels start
  25. with their predefined phase offsets (out_altvoltageY_phase).
  26. Writing this file has the effect as driving the external
  27. /SYNC pin low.
