Well, I read it, and it is still fairly high level with no mention at
all of "DPLL".  I hope that the new RTNL states will cover other
possible EEC implementations, too.

The "Reference source selection mechanism" is also quite vague.  Your
patch is more specific:

+enum if_eec_src {
+       IF_EEC_SRC_INVALID = 0,
+       IF_EEC_SRC_UNKNOWN,
+       IF_EEC_SRC_SYNCE,
+       IF_EEC_SRC_GNSS,
+       IF_EEC_SRC_PTP,
+       IF_EEC_SRC_EXT,
+       __IF_EEC_SRC_MAX,
+};

But I guess your list is reasonable.  It can always be expanded, right?

Yes, thanks for doing that.

Thanks,
