| phandle to a "simple-battery" compatible node. |
| |
| This property must be a phandle to a node using the format described |
| in battery.yaml, with the following properties being required: |
| - precharge-current-microamp: maximum charge current during precharge phase |
| (typically 20% of battery capacity). |
| - charge-term-current-microamp: a charge cycle terminates when the battery voltage is |
| above recharge threshold, and the current is below this |
| setting (typically 10% of battery capacity). |
| |
| required: |
| - compatible |
| - reg |
| - interrupts |
| |
| additionalProperties: false |
| |
