A superficial scan does not give me any definite agreement on an approach.
The patchset also needs to be CCed to John Stultz. Without a summary I
still am not clear what this is supposed to address.

Tuning of the PTP clock can be done with driver specific configuration
rather than a new POSIX clock. That is at least how SGI_CYCLE is operating
which is similar.


Ok this goes more into something that may prove useful but it would be
very helpful still to have a clear discussion as to why this is all
needed. From what I can tell the functionality is already there and
another clock device (CLOCK_SGI_CYCLE) is already providing a model for
how a PTP clock could be controlled and used.
