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

   61   - compatible
   62   - reg
   63   - interrupts
