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>;
