+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>;
+ };
