1 | SPM AVS Wrapper 2 (SAW2) | ||
2 | |||
3 | The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the | ||
4 | Adaptive Voltage Scaling (AVS) hardware. The SPM is a programmable | ||
5 | micro-controller that transitions a piece of hardware (like a processor or | ||
6 | subsystem) into and out of low power modes via a direct connection to | ||
7 | the PMIC. It can also be wired up to interact with other processors in the | ||
8 | system, notifying them when a low power state is entered or exited. | ||
