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. |
