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.
