TWL BCI (Battery Charger Interface)



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.



Required properties:

- compatible:

  - "ti,twl4030-bci"

- interrupts: two interrupt lines from the TWL SIH (secondary

  interrupt handler) - interrupts 9 and 2.



Optional properties:

- ti,bb-uvolt: microvolts for charging the backup battery.

- ti,bb-uamp: microamps for charging the backup battery.



Examples:



bci {

   compatible = "ti,twl4030-bci";

   interrupts = <9>, <2>;

   ti,bb-uvolt = <3200000>;

   ti,bb-uamp = <150>;

};
