- 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>;
- };
