1	TWL BCI (Battery Charger Interface)
2	
3	The battery charger needs to interact with the USB phy in order
4	to know when charging is permissible, and when there is a connection
5	or disconnection.
6	
7	The choice of phy cannot be configured at a hardware level, so there
8	is no value in explicit configuration in device-tree.  Rather
9	if there is a sibling of the BCI node which is compatible with
10	"ti,twl4030-usb", then that is used to determine when and how
11	use USB power for charging.
12	
13	Required properties:
14	- compatible:
15	  - "ti,twl4030-bci"
16	- interrupts: two interrupt lines from the TWL SIH (secondary
17	  interrupt handler) - interrupts 9 and 2.
18	
19	Optional properties:
20	- ti,bb-uvolt: microvolts for charging the backup battery.
21	- ti,bb-uamp: microamps for charging the backup battery.
22	
23	Examples:
24	
25	bci {
26	   compatible = "ti,twl4030-bci";
27	   interrupts = <9>, <2>;
28	   ti,bb-uvolt = <3200000>;
29	   ti,bb-uamp = <150>;
30	};
