    Subject[PATCH v7 2/3] Add the bindings for the bq25150 and bq25155 500mA charging ICs from Texas Instruments.
    Date
    From: Ricardo Rivera-Matos <r-rivera-matos@ti.com>

    The BQ2515X family of devices are highly integrated battery management
    ICs that integrate the most common functions for wearable devices
    namely a charger, an output voltage rail, ADC for battery and system
    monitoring, and a push-button controller.
