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>;
