Binding for TI bq2415x Li-Ion Charger
Required properties:
- compatible: Should contain one of the following:
- “ti,bq24150”
- “ti,bq24150”
- “ti,bq24150a”
- “ti,bq24151”
- “ti,bq24151a”
- “ti,bq24152”
- “ti,bq24153”
- “ti,bq24153a”
- “ti,bq24155”
- “ti,bq24156”
- “ti,bq24156a”
- “ti,bq24158”
- reg: integer, i2c address of the device.
- ti,current-limit: integer, initial maximum current charger can pull
from power supply in mA. - ti,weak-battery-voltage: integer, weak battery voltage threshold in mV.
The chip will use slow precharge if battery voltage is below this value. - ti,battery-regulation-voltage: integer, maximum charging voltage in mV.
- ti,charge-current: integer, maximum charging current in mA.
- ti,termination-current: integer, charge will be terminated when current in
constant-voltage phase drops below this value (in mA). - ti,resistor-sense: integer, value of sensing resistor in milliohm.
Optional properties:
- ti,usb-charger-detection: phandle to usb charger detection device.
(required for auto mode)
Example from Nokia N900:
bq24150a {
compatible = “ti,bq24150a”;
reg = <0x6b>;
ti,current-limit = <100>;
ti,weak-battery-voltage = <3400>;
ti,battery-regulation-voltage = <4200>;
ti,charge-current = <650>;
ti,termination-current = <100>;
ti,resistor-sense = <68>;
ti,usb-charger-detection = <&isp1704>;
};
