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, s4, 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, 5vs1, 5vs2 pm8994: s1, s2, s3, s4, s5, s6, s7, s8, s9, s10, s11, s12, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13, l14, l15, l16, l17, l18, l19, l20, l21, l22, l23, l24, l25, l26, l27, l28, l29, l30, l31, l32, lvs1, lvs2 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: 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: 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: 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: 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: 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: 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 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>; }; .... };
