Details

power-state-name

string

 
indicates a power state

This property is required.

Legal values: 'active', 'runtime-idle', 'suspend-to-idle', 'standby', 'suspend-to-ram', 'suspend-to-disk', 'soft-off'

substate-id

int

 
Platform specific identification.

min-residency-us

int

 
Minimum residency duration in microseconds.

How much time the residency in a given idle state must last for state entry
to be worthwhile energywise. It includes the time to enter into this state
and represents the "break-even" time to justify the time and power spent
on the work needed for entering and exiting the state based on how much actual energy
is saved once in the state, compared to choosing the next shallowest state.

exit-latency-us

int

 
Worst case latency in microseconds required to exit the idle state.

zephyr,pm-device-disabled

boolean

 
Disable system managed device power management for this state. When set,
the power management subsystem will not suspend devices before entering
this state.
