+description: |
+ The BQ2515x family 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.
+
+ Specifications about the charger can be found at:
+ http://www.ti.com/lit/ds/symlink/bq25150.pdf

+
+ pg-gpios:
+ description: |
+ 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.

+ GPIO used for hardware reset.
