+Stub Voltage Regulators
+
+stub-regulators are place-holder regulator devices which do not impact any
+hardware state. They provide a means for consumer devices to utilize all
+regulator features for testing purposes.
+
+Required properties:
+- compatible: Must be "qcom,stub-regulator".
+- regulator-name: A string used as a descriptive name for regulator outputs.
+
+Optional properties:
+- parent-supply: phandle to the parent supply/regulator node if one exists.
+- qcom,hpm-min-load: Load current in uA which corresponds to the minimum load
+ which requires the regulator to be in high power mode.
+- qcom,system-load: Load in uA present on regulator that is not captured by any
+ consumer request.
+
+All properties specified within the core regulator framework can also be used.
+These bindings can be found in regulator.txt.
+
+Example:
+
+/ {
+ pm8026_s3: regulator-s3 {
+ compatible = "qcom,stub-regulator";
+ regulator-name = "8026_s3";
+ qcom,hpm-min-load = <100000>;
