I have implemented in ice (also added back the DPLL_MODE_FREERUN).

Removed.

Hope Vadim will decide on this, the thing is merging in two patches
doesn't make much sense as there won't be any linking until both patches
are there, so most sense it would be if 3 are merged into one, but
then we will be back to one big blob patch issue.

>>4) remove function return values descriptions/lists

Fixed.

Added few things on this matter
- 1 dpll level attribute:
  - phase-shift - measuring the phase difference between dpll input
    and it's output
- 1 dpll-pin tuple level attribute:
  - pin-phase-adjust - set/get phase adjust of a pin on a dpll
- 2 pin level attributes:
  - pin-phase-adjust-min - provide user with min value that can be set
  - pin-phase-adjust-max - provide user with max value that can be set
- a constant:
  - DPLL_PHASE_SHIFT_DIVIDER similar to DPLL_TEMP_DIVIDER for producing
    fraction value of measured DPLL_A_PHASE_SHIFT
- implemented in dpll netlink and in ice

I didn't touch it, as we still need to discuss it, Jakub didn't respond
on v8 thread.
I don't see why we shall not name it the way. This is most meaningful
label for those pins for the user right now.

Thank you!
