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

125 | The content of each sub-node is defined by the standard binding for regulators - |
126 | see regulator.txt - with additional custom properties described below: | |
127 | ||
128 | - regulator-initial-mode: | |
129 | Usage: optional | |
130 | Value type: <u32> | |
e2adfacd SB |
131 | Description: 2 = Set initial mode to auto mode (automatically select |
132 | between HPM and LPM); not available on boost type | |
133 | regulators. | |
134 | ||
135 | 1 = Set initial mode to high power mode (HPM), also referred | |
136 | to as NPM. HPM consumes more ground current than LPM, but | |
e92a4047 SB |
137 | it can source significantly higher load current. HPM is not |
138 | available on boost type regulators. For voltage switch type | |
139 | regulators, HPM implies that over current protection and | |
e2adfacd SB |
140 | soft start are active all the time. |
141 | ||
142 | 0 = Set initial mode to low power mode (LPM). | |
143 | ||
144 | - qcom,ocp-max-retries: | |
145 | Usage: optional | |
146 | Value type: <u32> | |
147 | Description: Maximum number of times to try toggling a voltage switch | |
148 | off and back on as a result of consecutive over current | |
149 | events. | |
150 | ||
151 | - qcom,ocp-retry-delay: | |
152 | Usage: optional | |
153 | Value type: <u32> | |
154 | Description: Time to delay in milliseconds between each voltage switch | |
155 | toggle after an over current event takes place. | |
156 | ||
157 | - qcom,pin-ctrl-enable: | |
158 | Usage: optional | |
159 | Value type: <u32> | |
160 | Description: Bit mask specifying which hardware pins should be used to | |
161 | enable the regulator, if any; supported bits are: | |
162 | 0 = ignore all hardware enable signals | |
163 | BIT(0) = follow HW0_EN signal | |
164 | BIT(1) = follow HW1_EN signal | |
165 | BIT(2) = follow HW2_EN signal | |
166 | BIT(3) = follow HW3_EN signal | |
167 | ||
168 | - qcom,pin-ctrl-hpm: | |
169 | Usage: optional | |
170 | Value type: <u32> | |
171 | Description: Bit mask specifying which hardware pins should be used to | |
172 | force the regulator into high power mode, if any; | |
173 | supported bits are: | |
174 | 0 = ignore all hardware enable signals | |
175 | BIT(0) = follow HW0_EN signal | |
176 | BIT(1) = follow HW1_EN signal | |
177 | BIT(2) = follow HW2_EN signal | |
178 | BIT(3) = follow HW3_EN signal | |
179 | BIT(4) = follow PMIC awake state | |
180 | ||
181 | - qcom,vs-soft-start-strength: | |
182 | Usage: optional | |
183 | Value type: <u32> | |
184 | Description: This property sets the soft start strength for voltage | |
185 | switch type regulators; supported values are: | |
186 | 0 = 0.05 uA | |
187 | 1 = 0.25 uA | |
188 | 2 = 0.55 uA | |
189 | 3 = 0.75 uA | |

197 | s1: s1 { | |
