Matias Nitsche e118d99bf5 drivers/power/pm: Historically, the NuttX PM subsystem has consisted of two functional components: (1) an "Upper" part that detects state changes based on a random walk driven by activity levels, and (2) and "lower" part that implementst the state changes.
This change decouples that upper activity-based logic from the lower random walk logic and allows use of other upper state detection logic (such as a custom, application-specific state machine).

ligd 32075ef9d8 drivers/power/pm_activity.c: Add pm_staycount API for get stay numbers. This function is currently not used and a waste of FLASH space. 2019-01-27 11:19:26 -06:00
ligd e1622f60a6 drivers/power/pm: Use the start time of state btime) to calculate thrcnt; remove the loop whose count may be very big after the long idle 2018-11-10 07:30:23 -06:00
ligd a02f919bec drivers/power: PM: Add timer to decrease PM level automatically 2018-08-27 13:28:48 -06:00
Xiang Xiao af284c1e23 drivers/power/: PM: Don't update the power state in work thread: (1) Simplify the code logic and remove the work queue dependence, (2) Power calculation is too simple to delay into the work queue 2018-08-27 13:20:28 -06:00
Xiang Xiao 006b7d3963 drivers/power: PM: Add pm_stay and pm_relax function so special apps(e.g. mediaplayer) could disable suspend during playback much like linux kernel counterpart 2018-08-27 13:16:34 -06:00
