The SPM is a programmable ++micro-controller that transitions a piece of hardware (like a processor or ++subsystem) into and out of low power modes via a direct connection to ++the PMIC. It can also be wired up to interact with other processors in the ++system, notifying them when a low power state is entered or exited. ++ ++PROPERTIES ++ ++- compatible: ++ Usage: required ++ Value type: <string> ++ Definition: shall contain "qcom,saw2".
