+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>;
+ };
+
+ ....
+ };
