+title: TWL4030 BCI (Battery Charger Interface)
+
+description: |
+  The battery charger needs to interact with the USB phy in order to know when
+  charging is permissible, and when there is a connection or disconnection.
+
+  The choice of phy cannot be configured at a hardware level, so there is no
+  value in explicit configuration in device-tree. Rather if there is a sibling
+  of the BCI node which is compatible with "ti,twl4030-usb", then that is used
+  to determine when and how use USB power for charging.
