[net-next,v2,0/4] dpll: add all inputs phase offset monitor

Message

Kubalewski, Arkadiusz April 15, 2025, 6:15 p.m. UTC

Add simple dpll device level feature and capabilties infrastructure over
netlink dpll interface.
Using new infrastructure add new feature: ALL_INPUTS_PHASE_OFFSET_MONITOR.
Allow users control with two new attributes:
- DPLL_A_CAPABILITIES - for checking if dpll device is capable,
- DPLL_A_FEATURES - for enable/disable a features.
Implement feature in ice driver for dpll-enabled devices.

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

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

Verify feature is enabled:
$ ./tools/net/ynl/pyynl/cli.py \
 --spec Documentation/netlink/specs/dpll.yaml \
 --dump device-get
[
 [...]
 {'capabilities': {'all-inputs-phase-offset-monitor'},
  'clock-id': 4658613174691613800,
  'features': {'all-inputs-phase-offset-monitor'},
  'id': 1,
 [...]
]

Disable the feature:
$ ./tools/net/ynl/pyynl/cli.py \
 --spec Documentation/netlink/specs/dpll.yaml \
 --do device-set --json '{"id":1, \
 "features":0}'


Arkadiusz Kubalewski (4):
  dpll: use struct dpll_device_info for dpll registration
  dpll: add features and capabilities to dpll device spec
  dpll: features_get/set callbacks
  ice: add phase offset monitor for all PPS dpll inputs
