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>; |
|
};
