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>; | ||
}; | ||
|
||
.... | ||
}; |
