+SPM AVS Wrapper 2 (SAW2)
|
||
|
|
+
|
||
|
|
+The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the
|
||
|
|
+Adaptive Voltage Scaling (AVS) hardware. 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.

|
|
+ Definition: shall contain "qcom,saw2". A more specific value should be
|
||
|
|
+ one of:
|
