SMB135x battery charger



SMB135x is a single-cell switching mode battery charger. It can charge

the battery and power the system via the USB and AC adapter input.



The smb135x interface is via I2C bus.



Required Properties:

- compatible:			Must be "qcom,smb1357-charger" or  "qcom,smb1359-charger".

- reg:				The device 7-bit I2C address.



Optional Properties:



- interrupts			This indicates the IRQ number of the GPIO

				connected to the STAT pin.

- qcom,float-voltage-mv	 	Float Voltage in mV - the maximum voltage up to which

				the battery is charged. Supported range 3600mV to 4500mV

- qcom,charging-timeout		Maximum duration in minutes that a single charge

				cycle may last.  Supported values are: 0, 192, 384,

				768, and 1536.  A value of 0 means that no

				charge cycle timeout is used and charging can

				continue indefinitely.

- qcom,dc-psy-type		The type of charger connected to the DC path.

				Can be "Mains" or "Wireless"

- qcom,dc-psy-ma		The current in mA dc path can support. Must be specified if

				dc-psy-type is specified. Valid range 300mA to 2000mA.

- qcom,charging-disabled	Set this if charging should be disabled in the build

				by default. Useful in usecases where battery current

				needs to be profiled even when USB is present.

- qcom,recharge-thresh-mv	Specifies the minimum voltage drop in millivolts

				below the float voltage that is required in

				order to initiate a new charging cycle.

				Supported values are: 50, 100, 200 and 300mV.

- regulator-name		A string used as a descriptive name for OTG regulator.



Example:

	i2c@f9967000 {

		smb1357-charger@1b {

			compatible = "qcom,smb1357-charger";

			reg = <0x1b>;

			interrupt-parent = <&spmi_bus>;

			interrupts = <0x00 0xCD 0>;

			qcom,float-voltage-mv = <4200>;

			qcom,dc-psy-type = <8>;

			qcom,dc-psy-ma = <800>;

			qcom,charging-disabled;

			qcom,recharge-thresh-mv = <100>;

			regulator-name = "smb1357-otg";

		};

	};
