7 title: TWL4030 BCI (Battery Charger Interface)
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.
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.
