+
+      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).
