title: PM Domain Idle States binding description

maintainers:
  - Ulf Hansson <ulf.hansson@linaro.org>

description:
  A domain idle state node represents the state parameters that will be used to
  select the state when there are no active components in the PM domain.

properties:
  $nodename:
    const: domain-idle-states

patternProperties:
  "^(cpu|cluster|domain)-":
    type: object
    description:
      Each state node represents a domain idle state description.

properties:
      compatible:
        const: domain-idle-state

entry-latency-us:
        description:
          The worst case latency in microseconds required to enter the idle
          state. Note that, the exit-latency-us duration may be guaranteed only
          after the entry-latency-us has passed.

exit-latency-us:
        description:
          The worst case latency in microseconds required to exit the idle
          state.

min-residency-us:
        description:
          The minimum residency duration in microseconds after which the idle
          state will yield power benefits, after overcoming the overhead while
          entering the idle state.

required:
      - compatible
      - entry-latency-us
      - exit-latency-us
      - min-residency-us
