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.
