| 72 | The regulator node houses sub-nodes for each regulator within the device. Each | |
| 73 | sub-node is identified using the node's name, with valid values listed for each | |
| 74 | of the PMICs below. | |

| 88 | The content of each sub-node is defined by the standard binding for regulators - | |
| 89 | see regulator.txt - with additional custom properties described below: | |
| 90 | ||
| 91 | - regulator-initial-mode: | |
| 92 | Usage: optional | |
| 93 | Value type: <u32> | |
| 94 | Descrption: 1 = Set initial mode to high power mode (HPM), also referred | |
| 95 | to as NPM. HPM consumes more ground current than LPM, but | |
| 96 | it can source significantly higher load current. HPM is not | |
| 97 | available on boost type regulators. For voltage switch type | |
| 98 | regulators, HPM implies that over current protection and | |
| 99 | soft start are active all the time. 0 = Set initial mode to | |
| 100 | low power mode (LPM). | |
| 101 | ||
| 102 | Example: | |
| 103 | ||
| 104 | regulators { | |
| 105 | compatible = "qcom,pm8941-regulators"; | |
| 106 | vdd_l1_l3-supply = <&s1>; | |
| 107 | ||
| 108 | s1: s1 { | |
| 109 | regulator-min-microvolt = <1300000>; | |
| 110 | regulator-max-microvolt = <1400000>; | |
| 111 | }; | |
| 112 | ||
| 113 | ... | |
| 114 | ||
| 115 | l1: l1 { | |
| 116 | regulator-min-microvolt = <1225000>; | |
| 117 | regulator-max-microvolt = <1300000>; | |
| 118 | }; | |
| 119 | ||
| 120 | .... | |
| 121 | }; |
