20 +SPM AVS Wrapper 2 (SAW2)
22 +The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the
23 +Adaptive Voltage Scaling (AVS) hardware. The SPM is a programmable
24 +micro-controller that transitions a piece of hardware (like a processor or
25 +subsystem) into and out of low power modes via a direct connection to
26 +the PMIC. It can also be wired up to interact with other processors in the
27 +system, notifying them when a low power state is entered or exited.
33 + Value type: <string>
34 + Definition: shall contain "qcom,saw2". A more specific value should be
43 + Value type: <prop-encoded-array>
44 + Definition: the first element specifies the base address and size of
45 + the register region. An optional second element specifies
46 + the base address and size of the alias register region.
52 + compatible = "qcom,saw2";
