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>;
s1: s1 {
regulator-min-microvolt = <1300000>;
regulator-max-microvolt = <1400000>;
};
...
l1: l1 {
regulator-min-microvolt = <1225000>;
regulator-max-microvolt = <1300000>;
};
....
};
Example 2:
saw3: syscon@9A10000 {
compatible = "syscon";
reg = <0x9A10000 0x1000>;
};
...
spm-regulators {
compatible = "qcom,pm8994-regulators";
qcom,saw-reg = <&saw3>;
s8 {
qcom,saw-slave;
};
s9 {
qcom,saw-slave;
};
s10 {
qcom,saw-slave;
};
pm8994_s11_saw: s11 {
qcom,saw-leader;
regulator-always-on;
regulator-min-microvolt = <900000>;
regulator-max-microvolt = <1140000>;
