The regulator node houses sub-nodes for each regulator within the device. Each
sub-node is identified using the node's name, with valid values listed for each
of the PMICs below.
pm8841:
s1, s2, s3, s4, s5, s6, s7, s8
pm8916:
s1, s2, s3, s4, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13,
l14, l15, l16, l17, l18
pm8941:
s1, s2, s3, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13, l14,
l15, l16, l17, l18, l19, l20, l21, l22, l23, l24, lvs1, lvs2, lvs3,
mvs1, mvs2
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>
Descrption: 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).
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>;
};
....
};
