Subject: [PATCH v14 3/4] dt-bindings: power: Add the bindings for the bq2515x family of chargers.
Date: Tue, 30 Jun 2020 16:54:25 -0500
Message-ID: <20200630215426.26450-4-r-rivera-matos@ti.com> (raw)
In-Reply-To: <20200630215426.26450-1-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.
