| 51 | phandle to a "simple-battery" compatible node. | |
| 52 | ||
| 53 | This property must be a phandle to a node using the format described | |
| 54 | in battery.yaml, with the following properties being required: | |
| 55 | - precharge-current-microamp: maximum charge current during precharge phase | |
| 56 | (typically 20% of battery capacity). | |
| 57 | - charge-term-current-microamp: a charge cycle terminates when the battery voltage is | |
| 58 | above recharge threshold, and the current is below this | |
| 59 | setting (typically 10% of battery capacity). | |
| 60 | ||
