| shunt-resistor-micro-ohms: |
| description: |
| The value of curent sense resistor in microohms. If not provided, |
| the current reading and overcurrent alert is disabled. |
| |
| adi,shutdown-threshold-microamp: |
| description: |
| Specifies the current level at which an over current alert occurs. |
| If not provided, the overcurrent alert is configured to max ADC range |
| based on shunt-resistor-micro-ohms. |
| |
| adi,vrange-high-enable: |
| description: |
| Specifies which internal voltage divider to be used. A 1 selects |
| a 7:2 voltage divider while a 0 selects a 14:1 voltage divider. |
