I am surprised this notifier didn't already report the substate id, it seems important since different substate obviously are defined for a reason, they can be having a different effect on the system. Signed-off-by: Declan Snyder <declan.snyder@nxp.com> (cherry picked from commit ae1f131)
Add two helper functions to convert power management states between enum and string: - pm_state_to_string() - pm_state_from_string() Signed-off-by: Yongxu Wang <yongxu.wang@nxp.com> (cherry picked from commit 8767cec)
Some pieces of the system may have custom types of constraints that they define based on different effects and reasons than just the standard "zephyr,disabling-states". To avoid every single one of these component reinventing the wheel, make some common APIs to handle these type of custom constraint lists. Signed-off-by: Declan Snyder <declan.snyder@nxp.com> (cherry picked from commit a4225b1)
Add function for getting and putting a lock for all power states. It is much faster version of requesting 0 us latency with actual intention to disable all power states. Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no> (cherry picked from commit 336e89e)
Add test case that validates behavior of pm_policy_state_all_lock_get and pm_policy_state_all_lock_put. Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no> (cherry picked from commit 3595c9d)
