Subject: [PATCH v4 0/5] regulator: add under-voltage support (part 2)

This series add under-voltage and emergency shutdown for system critical
regulators

changes v4:
- rebase against latest regulator/for-next
- drop mainlined patches
- rename regulator-uv-survival-time-ms to regulator-uv-less-critical-window-ms
  to fit it to actual use case
- avoid some of words in commit messages
- us switch case to parse critical events

changes v3:
- add system-critical-regulator property
- add regulator-uv-survival-time-ms property
- implement default policy for system critical uv events

changes v2:
- drop event forwarding support
- use emergency shutdown directly instead of generating under-voltage
  error event.
- fix devicetree patch
- drop interrupt-names support

Oleksij Rempel (5):
  regulator: dt-bindings: Add system-critical-regulator property
  regulator: Introduce handling for system-critical under-voltage events
  regulator: dt-bindings: Allow system-critical marking for
    fixed-regulator
  regulator: dt-bindings: Add 'regulator-uv-less-critical-window-ms'
    property
  regulator: Implement uv_survival_time for handling under-voltage
    events
