++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>;
++ };
