| |
| 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> |
| 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: <u32> |
| 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: <u32> |
| 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: <u32> |
| 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: <u32> |
| 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: <u32> |
| 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 |
| |
| - qcom,saw-slave: |
| Usage: optional |
| Value type: <boo> |
| Description: SAW controlled gang slave. Will not be configured. |
| |
| - qcom,saw-leader: |
| Usage: optional |
| Value type: <boo> |
| Description: SAW controlled gang leader. Will be configured as |
| SAW regulator. |
| |
| Example: |
| |
| regulators { |
| compatible = "qcom,pm8941-regulators"; |
