PM Domain Idle State Node:

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 domain.

The state node has the following parameters -

  • compatible:
    Usage: Required
    Value type:
    Definition: Must be “domain-idle-state”.

  • entry-latency-us
    Usage: Required
    Value type:
    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:
    Definition: u32 value representing worst case latency

          in microseconds required to exit the idle state.
    
  • min-residency-us
    Usage: Required
    Value type:
    Definition: u32 value representing minimum residency duration

          in microseconds after which the idle state will yield
          power benefits after overcoming the overhead in entering
    

    i the idle state.
