1	Binding for TI bq2415x Li-Ion Charger
2	
3	Required properties:
4	- compatible: Should contain one of the following:
5	 * "ti,bq24150"
6	 * "ti,bq24150"
7	 * "ti,bq24150a"
8	 * "ti,bq24151"
9	 * "ti,bq24151a"
10	 * "ti,bq24152"
11	 * "ti,bq24153"
12	 * "ti,bq24153a"
13	 * "ti,bq24155"
14	 * "ti,bq24156"
15	 * "ti,bq24156a"
16	 * "ti,bq24158"
17	- reg:			   integer, i2c address of the device.
18	- ti,current-limit:	   integer, initial maximum current charger can pull
19				   from power supply in mA.
20	- ti,weak-battery-voltage: integer, weak battery voltage threshold in mV.
21				   The chip will use slow precharge if battery voltage
22				   is below this value.
23	- ti,battery-regulation-voltage: integer, maximum charging voltage in mV.
24	- ti,charge-current:	   integer, maximum charging current in mA.
25	- ti,termination-current:  integer, charge will be terminated when current in
26				   constant-voltage phase drops below this value (in mA).
27	- ti,resistor-sense:	   integer, value of sensing resistor in milliohm.
28	
29	Optional properties:
30	- ti,usb-charger-detection: phandle to usb charger detection device.
31				    (required for auto mode)
32	
33	Example from Nokia N900:
34	
35	bq24150a {
36		compatible = "ti,bq24150a";
37		reg = <0x6b>;
38	
39		ti,current-limit = <100>;
40		ti,weak-battery-voltage = <3400>;
41		ti,battery-regulation-voltage = <4200>;
42		ti,charge-current = <650>;
43		ti,termination-current = <100>;
44		ti,resistor-sense = <68>;
45	
46		ti,usb-charger-detection = <&isp1704>;
47	};
