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: + Definition: shall contain "qcom,saw2".
