Merge "power: smb349-charger: Add smb349 charger driver"

Summit smb349 battery charger

SMB349 is a single-cell battery charger. It can charge

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

The smb349 interface is via I2C bus.

Required Properties:

- compatible:			Must be "qcom,smb349-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,chg-valid-gpio		GPIO which indicates the charger presence.

				This GPIO is connected to the SYSOK pin.

- qcom,fastchg-current-max-ma Fast Charging current in mA. Supported range is

				from 1000mA to 4000mA.

- qcom,chg-autonomous-mode	This is a bool property and it indicates that the

				charger is configured for autonomous operation and

				does not require any software configuration.

- qcom,enable-chg-type-detection This is bool property and it indicates

				if charger detection is supported by this

				driver.

- qcom,disable-apsd		This is a bool property which disables Automatic

				power source detection (apsd). If this is set

				charger detection is done by DCIN UV irq.

- qcom,charger-disabled	This is a bool property which disables charging.

- qcom,reload-smb-config	This is a bool property to indicate if the

				smb register configuration needs to be reloaded

				when the charger is removed.

- qcom,bms-psy-name		This is a string and it points to the bms

				power supply name.

Example:

	i2c@f9967000 {

		smb349-charger@1b {

			compatible = "qcom,smb349-charger";

			reg = <0x1b>;

			interrupt-parent = <&msmgpio>;

			interrupts = <48 0x0>;

			qcom,chg-valid-gpio = <&msm_gpio 13 0x00>;

			qcom,fastchg-current-max-ma = <3500>;

			qcom,chg-autonomous-mode;

			qcom,bms-psy-name = "bms";

		};

	};

	  SMB349 be operated as a slave device via the power supply

	  framework.

	 Say Y to enable support for the SMB349 switching mode based charger.

	 The driver supports charging control (enable/disable) and

	 charge-current limiting. It also provides USB VBUS detection and

	 notification support. The driver controls SMB349 via I2C and

	 supports device-tree interface.
