1Binding for TI bq2415x Li-Ion Charger
2
3Required 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
29Optional properties:
30- ti,usb-charger-detection: phandle to usb charger detection device.
31			    (required for auto mode)
