+description: |
+ Bindings for the Analog Devices AD7280a Battery Monitoring System.
+ Used in devices such as hybrid electric cars, battery backup and power tools.
+ Multiple chips can be daisy chained and accessed via a single SPI interface.
+ Data sheet found here:

+ description:
+ Allows limiting of scope of which channels are considered for voltage
+ alerts, typically because not all are wired to anything. Only applies to
+ last device in the daisy chain.
