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
