-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
-power-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.
-
-Multiple revisions of the SAW hardware are supported using these Device Nodes.
-SAW2 revisions differ in the register offset and configuration data. Also, the
-same revision of the SAW in different SoCs may have different configuration
-data due the differences in hardware capabilities. Hence the SoC name, the
-version of the SAW hardware in that SoC and the distinction between cpu (big
-or Little) or cache, may be needed to uniquely identify the SAW register
-configuration and initialization data. The compatible string is used to
-indicate this parameter.

-- compatible:
- Usage: required
- Value type: <string>
- Definition: Must have
- "qcom,saw2"
- A more specific value could be one of:
- "qcom,apq8064-saw2-v1.1-cpu"
- "qcom,msm8226-saw2-v2.1-cpu"
- "qcom,msm8974-saw2-v2.1-cpu"
- "qcom,apq8084-saw2-v2.1-cpu"
-
-- 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.
-
-- regulator:
- Usage: optional
- Value type: boolean
- Definition: Indicates that this SPM device acts as a regulator device
- device for the core (CPU or Cache) the SPM is attached
- to.
