Thinking about modes "holdover" and "freerun".
1) You don't use them anywhere in this patchset, please remove them
   until they are needed. ptp_ocp and ice uses automatic, mlx5 uses
   manual. Btw, are there any other unused parts of UAPI? If yes, could
   you please remove them too?

2) I don't think it is correct to have them.
   a) to achieve holdover:
      if state is LOCKED_HO_ACQ you just disconnect all input pins.
   b) to achieve freerun:
      if state LOCKED you just disconnect all input pins.
   So don't mangle the mode with status.

I don't think I have any objections against "input", but out of
curiosity, why you changed that from "source"?

Wouldn't it make sense to add some small documentation blocks to the
attrs? IDK.

Well this is not entierly true, the mode is not a state.
Technically in those modes the user would not be able to set any states
on the pins.
The modes are supported on the synchronizer chips we are using, altough
the ice driver does not have this support enabled yet.
So I am removing those for now, if they would be needed, we will submit the
patches for it.

Agreed to previous version review comment from Jakub,
to use either: input/output or source/sink naming scheme.

Actually already tried that, but after all they did not generate any docs
for attr enums. So this need also fix in ynl-gen-c.py

I think this would be useful, but only if we could use them in the dpll.rst.
Right now it is not case, but we already try to incorporate other enums
description there, for now it is broken, but will try to fix this in the near
future.

Thank you!
