| 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. |
