1	Binding for TI bq25890 Li-Ion Charger
2	
3	Required properties:
4	- compatible: Should contain one of the following:
5	    * "ti,bq25890"
6	- reg: integer, i2c address of the device.
7	- ti,battery-regulation-voltage: integer, maximum charging voltage (in uV);
8	- ti,charge-current: integer, maximum charging current (in uA);
9	- ti,termination-current: integer, charge will be terminated when current in
10	    constant-voltage phase drops below this value (in uA);
11	- ti,precharge-current: integer, maximum charge current during precharge
12	    phase (in uA);
13	- ti,minimum-sys-voltage: integer, when battery is charging and it is below
14	    minimum system voltage, the system will be regulated above
15	    minimum-sys-voltage setting (in uV);
16	- ti,boost-voltage: integer, VBUS voltage level in boost mode (in uV);
17	- ti,boost-max-current: integer, maximum allowed current draw in boost mode
18	    (in uA).
19	
20	Optional properties:
21	- ti,boost-low-freq: boolean, if present boost mode frequency will be 500kHz,
22	    otherwise 1.5MHz;
23	- ti,use-ilim-pin: boolean, if present the ILIM resistor will be used and the
24	    input current will be the lower between the resistor setting and the IINLIM
25	    register setting;
26	- ti,thermal-regulation-threshold: integer, temperature above which the charge
27	    current is lowered, to avoid overheating (in degrees Celsius). If omitted,
28	    the default setting will be used (120 degrees);
29	
30	Example:
31	
32	bq25890 {
33	        compatible = "ti,bq25890";
34	        reg = <0x6a>;
35	
36	        ti,battery-regulation-voltage = <4200000>;
37	        ti,charge-current = <1000000>;
38	        ti,termination-current = <50000>;
39	        ti,precharge-current = <128000>;
40	        ti,minimum-sys-voltage = <3600000>;
41	        ti,boost-voltage = <5000000>;
42	        ti,boost-max-current = <1000000>;
43	
44	        ti,use-ilim-pin;
45	        ti,thermal-regulation-threshold = <120>;
46	};
