  1. PM Domain Idle State Node:
  2. A domain idle state node represents the state parameters that will be used to
  3. select the state when there are no active components in the domain.
  4. The state node has the following parameters -
  5. - compatible:
  6. Usage: Required
  7. Value type: <string>
  8. Definition: Must be "domain-idle-state".
  9. - entry-latency-us
  10. Usage: Required
  11. Value type: <prop-encoded-array>
  12. Definition: u32 value representing worst case latency in
  13. microseconds required to enter the idle state.
  14. The exit-latency-us duration may be guaranteed
  15. only after entry-latency-us has passed.
  16. - exit-latency-us
  17. Usage: Required
  18. Value type: <prop-encoded-array>
  19. Definition: u32 value representing worst case latency
  20. in microseconds required to exit the idle state.
  21. - min-residency-us
  22. Usage: Required
  23. Value type: <prop-encoded-array>
  24. Definition: u32 value representing minimum residency duration
  25. in microseconds after which the idle state will yield
  26. power benefits after overcoming the overhead in entering
  27. i the idle state.
