14 Bindings for the Analog Devices AD7280a Battery Monitoring System.
15 Used in devices such as hybrid electric cars, battery backup and power tools.
16 Multiple chips can be daisy chained and accessed via a single SPI interface.

31 adi,voltage-alert-last-chan:
32 $ref: /schemas/types.yaml#/definitions/uint32
34 Allows limiting of scope of which channels are considered for voltage
35 alerts, typically because not all are wired to anything. Only applies to
36 last device in the daisy chain.
40 adi,acquisition-time-ns:
42 Additional time may be needed to charge the sampling capacitors depending
45 enum: [400, 800, 1200, 1600]
47 adi,thermistor-termination:
50 Enable the thermistor termination function.
