description: |
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
