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.
