[PATCH v1 0/2] regulator: forward undervoltage events downstream

[Oleksij Rempel]

This short series lets critical supply events propagate to consumers.
It introduces an opt-in helper in the core to forward
REGULATOR_EVENT_UNDER_VOLTAGE from a regulator's supply to the
consumer's notifier chain, and opts the fixed regulator in at probe.

Only under-voltage is forwarded to avoid surprises. Behavior is
unchanged unless a driver calls the helper. No DT/UAPI/ABI changes.

Oleksij Rempel (2):
  regulator: core: add infrastructure for downstream event forwarding
  regulator: fixed: opt in to downstream event forwarding
