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. PROPERTIES - compatible: Usage: required Value type: <string> Definition: shall contain "qcom,saw2". A more specific value should be one of: "qcom,saw2-v1" "qcom,saw2-v1.1" "qcom,saw2-v2" "qcom,saw2-v2.1" - reg: Usage: required Value type: <prop-encoded-array> Definition: the first element specifies the base address and size of the register region. An optional second element specifies the base address and size of the alias register region. Example: regulator@2099000 { compatible = "qcom,saw2"; reg = <0x02099000 0x1000>, <0x02009000 0x1000>; };
