TWL BCI (Battery Charger Interface)



Required properties:

- compatible:

  - "ti,twl4030-bci"

- interrupts: two interrupt lines from the TWL SIH (secondary

  interrupt handler) - interrupts 9 and 2.



Optional properties:

- ti,bb-uvolt: microvolts for charging the backup battery.

- ti,bb-uamp: microamps for charging the backup battery.



Examples:



bci {

   compatible = "ti,twl4030-bci";

   interrupts = <9>, <2>;

   ti,bb-uvolt = <3200000>;

   ti,bb-uamp = <150>;

TI BQ24735 Charge Controller

~~~~~~~~~~



Required properties :

 - compatible : "ti,bq24735"



Optional properties :

 - interrupts : Specify the interrupt to be used to trigger when the AC

   adapter is either plugged in or removed.

 - ti,ac-detect-gpios : This GPIO is optionally used to read the AC adapter

   presence. This is a Host GPIO that is configured as an input and

   connected to the bq24735.

 - ti,charge-current : Used to control and set the charging current. This value

   must be between 128mA and 8.128A with a 64mA step resolution. The POR value

   is 0x0000h. This number is in mA (e.g. 8192), see spec for more information

   about the ChargeCurrent (0x14h) register.

 - ti,charge-voltage : Used to control and set the charging voltage. This value

   must be between 1.024V and 19.2V with a 16mV step resolution. The POR value

   is 0x0000h. This number is in mV (e.g. 19200), see spec for more information

   about the ChargeVoltage (0x15h) register.

 - ti,input-current : Used to control and set the charger input current. This

   value must be between 128mA and 8.064A with a 128mA step resolution. The

   POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for

   more information about the InputCurrent (0x3fh) register.



Example:



	bq24735@9 {

		compatible = "ti,bq24735";

		reg = <0x9>;

		ti,ac-detect-gpios = <&gpio 72 0x1>;

	}
