+Binding for TI bq25150 500-mA Linear charger
+
+The BQ25150 is a highly integrated battery charge management IC that integrates
+the most common functions for wearable devices, namely a charger, an
+output voltage rail, ADC for battery and system monitoring, and
+push-button controller.
+
+Required Properties:
+	- compatible: Should contain one of the following:
+		"ti,bq25150"
+		"ti,bq25155"
+	- reg: int I2c address 0x6b
+	- #address-cells: 1;
+	- #size-cells: = 0;
+
+Optional Properties:
+	- ti,battery-regulation-voltage: integer, maximum charging voltage in mV.
+		Values range from 3600->4600mV
+	- ti,charge-current: integer, maximum charging current in mA.
+		Values range from 50->600mA
+	- reset-gpios: GPIO used for Master reset
+	- low-power-gpios: GPIO used for low power mode of IC.
+	- charge-enable-gpios: GPIO used to turn on and off charging.
+	- pg-gpios: GPIO used for connecting the bq2515x device PG (Power Good)
+		pin.  This pin should be used if possible as this is the
+		recommended way to obtain the charger's input PG state.
+		If this pin is not specified a software-based approach for PG
+		detection is used.
+
+Example
+bq25150@6b {
+	compatible = "ti,bq25150";
+	reg = <0x6b>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	pg-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
+	reset-gpios = <&gpio0 14 GPIO_ACTIVE_HIGH>;
+	low-power-gpios = <&gpio0 15 GPIO_ACTIVE_HIGH>;
+	charge-enable-gpios = <&gpio0 13 GPIO_ACTIVE_LOW>;
+
+	ti,charge-current = <300>;
+	ti,battery-regulation-voltage = <4200>;
+};
