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