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>;

	};
