Merge branch 'dpll-add-all-inputs-phase-offset-monitor'

Arkadiusz Kubalewski says:

====================
dpll: add all inputs phase offset monitor

Add dpll device level feature: phase offset monitor.

Phase offset measurement is typically performed against the current active
source. However, some DPLL (Digital Phase-Locked Loop) devices may offer
the capability to monitor phase offsets across all available inputs.
The attribute and current feature state shall be included in the response
message of the ``DPLL_CMD_DEVICE_GET`` command for supported DPLL devices.
In such cases, users can also control the feature using the
``DPLL_CMD_DEVICE_SET`` command by setting the ``enum dpll_feature_state``
values for the attribute.
Once enabled the phase offset measurements for the input shall be returned
in the ``DPLL_A_PIN_PHASE_OFFSET`` attribute.

Implement feature support in ice driver for dpll-enabled devices.

Verify capability:
$ ./tools/net/ynl/pyynl/cli.py \
 --spec Documentation/netlink/specs/dpll.yaml \
 --dump device-get
[{'clock-id': 4658613174691613800,
  'id': 0,
  'lock-status': 'locked-ho-acq',
  'mode': 'automatic',
  'mode-supported': ['automatic'],
  'module-name': 'ice',
  'type': 'eec'},
 {'clock-id': 4658613174691613800,
  'id': 1,
  'lock-status': 'locked-ho-acq',
  'mode': 'automatic',
  'mode-supported': ['automatic'],
  'module-name': 'ice',
  'phase-offset-monitor': 'disable',
  'type': 'pps'}]

Enable the feature:
$ ./tools/net/ynl/pyynl/cli.py \
 --spec Documentation/netlink/specs/dpll.yaml \
 --do device-set --json '{"id":1, "phase-offset-monitor":"enable"}'

Verify feature is enabled:
$ ./tools/net/ynl/pyynl/cli.py \
 --spec Documentation/netlink/specs/dpll.yaml \
 --dump device-get
