Value type: <string>
Definition: Must be "domain-idle-state".
- entry-latency-us
Usage: Required
Value type: <prop-encoded-array>
Definition: u32 value representing worst case latency in
microseconds required to enter the idle state.
The exit-latency-us duration may be guaranteed
only after entry-latency-us has passed.
- exit-latency-us
Usage: Required
Value type: <prop-encoded-array>
Definition: u32 value representing worst case latency
in microseconds required to exit the idle state.
- min-residency-us
Usage: Required
Value type: <prop-encoded-array>
Definition: u32 value representing minimum residency duration
in microseconds after which the idle state will yield
