- 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>;
- regulator-min-microvolt = <1300000>;
- regulator-max-microvolt = <1300000>;
- };
- pm8026_l1: regulator-l1 {
- compatible = "qcom,stub-regulator";
- regulator-name = "8026_l1";
- parent-supply = <&pm8026_s3>;
- qcom,hpm-min-load = <10000>;
- regulator-min-microvolt = <1225000>;
- regulator-max-microvolt = <1225000>;
- };
- pm8026_l20: regulator-l20 {
- compatible = "qcom,stub-regulator";
- regulator-name = "8026_l20";
- qcom,hpm-min-load = <5000>;
- regulator-min-microvolt = <3075000>;
- regulator-max-microvolt = <3075000>;
- };
- };
