Binding for TI bq24257 Li-Ion Charger



Required properties:

- compatible: Should contain one of the following:

 * "ti,bq24257"

- reg:			   integer, i2c address of the device.

- ti,battery-regulation-voltage: integer, maximum charging voltage in uV.

- ti,charge-current:	   integer, maximum charging current in uA.

- ti,termination-current:  integer, charge will be terminated when current in

			   constant-voltage phase drops below this value (in uA).



Example:



bq24257 {

	compatible = "ti,bq24257";

	reg = <0x6a>;



	ti,battery-regulation-voltage = <4200000>;

	ti,charge-current = <1000000>;

	ti,termination-current = <50000>;

};
