Kalle/Thomas,
Thanks for your feedback.

This time sync support is different from the one that mac80211 maintains with mesh peers.
This time sync is mostly used by upper layers for several applications (like audio).
In this case we allow the user to configure for each zone who will be the synchronizer.
You can refer to the following Application Report (chapter 6) for more information: http://www.ti.com/lit/an/swaa166/swaa166.pdf

BR,

Guy Mishol

Yeah, and why use debugfs?
