- 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>;
- };
