The content of each sub-node is defined by the standard binding for regulators -
|
see regulator.txt - with additional custom properties described below:
|
|
- regulator-initial-mode:
|
Usage: optional
|
Value type: <u32>
|
Description: 2 = Set initial mode to auto mode (automatically select
|
between HPM and LPM); not available on boost type
|
regulators.
|
|
1 = Set initial mode to high power mode (HPM), also referred
|
to as NPM. HPM consumes more ground current than LPM, but
|
it can source significantly higher load current. HPM is not
|
available on boost type regulators. For voltage switch type
|
regulators, HPM implies that over current protection and
|
soft start are active all the time.
|
|
0 = Set initial mode to low power mode (LPM).
|
|
- qcom,ocp-max-retries:
|
Usage: optional
|
Value type: <u32>
|
Description: Maximum number of times to try toggling a voltage switch
|
off and back on as a result of consecutive over current
|
events.
|
|
- qcom,ocp-retry-delay:
|
Usage: optional
|
Value type: <u32>
|
Description: Time to delay in milliseconds between each voltage switch
|
toggle after an over current event takes place.
|
|
- qcom,pin-ctrl-enable:
|
Usage: optional
|
Value type: <u32>
|
Description: Bit mask specifying which hardware pins should be used to
|
enable the regulator, if any; supported bits are:
|
0 = ignore all hardware enable signals
|
BIT(0) = follow HW0_EN signal
|
BIT(1) = follow HW1_EN signal
|
BIT(2) = follow HW2_EN signal
|
BIT(3) = follow HW3_EN signal
|
|
- qcom,pin-ctrl-hpm:
|
Usage: optional
|
Value type: <u32>
|
Description: Bit mask specifying which hardware pins should be used to
|
force the regulator into high power mode, if any;
|
supported bits are:
|
0 = ignore all hardware enable signals
|
BIT(0) = follow HW0_EN signal
|
BIT(1) = follow HW1_EN signal
|
BIT(2) = follow HW2_EN signal
|
BIT(3) = follow HW3_EN signal
|
BIT(4) = follow PMIC awake state
|
|
- qcom,vs-soft-start-strength:
|
Usage: optional
|
Value type: <u32>
|
Description: This property sets the soft start strength for voltage
|
switch type regulators; supported values are:
|
0 = 0.05 uA
|
1 = 0.25 uA
|
2 = 0.55 uA
|
3 = 0.75 uA
|
|
- qcom,saw-slave:
|
Usage: optional
|
Value type: <boo>
|
Description: SAW controlled gang slave. Will not be configured.
|
|
- qcom,saw-leader:
|
Usage: optional
|
Value type: <boo>
|
Description: SAW controlled gang leader. Will be configured as
|
SAW regulator.
|
|
Example:
|
|
regulators {
|
compatible = "qcom,pm8941-regulators";
|
vdd_l1_l3-supply = <&s1>;
|

regulator-min-microvolt = <1300000>;
|
regulator-max-microvolt = <1400000>;
|
};
|
|
...
