Currently the power supply device tree documentation is spread in .../bindings/power_supply and .../bindings/power. This unifies the files for chargers and battery fuel gauges in .../bindings/power/supply and the ones for system reset/shutdown in .../bindings/power/reset (same structure as used for the drivers itself).

- compatible: Should contain one of the following:
|
|
* "ti,bq24150"
|
|
* "ti,bq24150"
|
|
* "ti,bq24150a"
|
|
* "ti,bq24151"
|
|
* "ti,bq24151a"
|
|
* "ti,bq24152"

|
|
- 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:

|
|
|
|
ti,usb-charger-detection = <&isp1704>;
|
|
};
