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)
|
||

|
|
ti,weak-battery-voltage = <3400>;
|
||
|
|
ti,battery-regulation-voltage = <4200>;
|
||
|
|
ti,charge-current = <650>;
|
||
|
|
ti,termination-current = <100>;
|
||
|
|
