I think you're trying to put too much information into the device
name.

Currently it's:

  idt <company name> cm <platform> - phc <exact device type>

Where usually we have, taking your example:

  tps65912 <chip> - regulator <subsystem>

So assuming the PTP HW Clock is just a clock it should be:

  8a3400 <chip> - clock <subsystem>

It's difficult to say without seeing the associated child device(s).
When do you propose to upstream those?  Maybe they should be part of
this initial set.  I think that would help a lot.
