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>;
|
||
|
|
};
