This should use the new YAML binding style.

+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
Those values should be in uV and uA. Also the values basically
describe the dumb battery, so please use this binding:
Documentation/devicetree/bindings/power/supply/battery.txt
Ack
+ - 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 {
charger@6b
