    7 title: TWL4030 BCI (Battery Charger Interface)
    8 
    9 description: |
   10   The battery charger needs to interact with the USB phy in order to know when
   11   charging is permissible, and when there is a connection or disconnection.
   12 
   13   The choice of phy cannot be configured at a hardware level, so there is no
   14   value in explicit configuration in device-tree. Rather if there is a sibling
   15   of the BCI node which is compatible with "ti,twl4030-usb", then that is used
   16   to determine when and how use USB power for charging.
