The device enters low-power mode on idle to save power. Enabling an event puts
the device out of the low-power since the ADC autonomously samples to assert
the event condition.
IIO trigger support
===================
An IIO trigger ``ad4062-devX`` is registered by the driver to be used by the
same device, to capture samples to a software buffer. It is required to attach
the trigger to the device by setting the ``current_trigger`` before enabling
and reading the buffer.
The acquisition is sequential and bounded by the protocol timings, software
latency and internal timings, the sample rate is not configurable. The burst
averaging mode does impact the effective sample rate, since it increases the
internal timing to output a single sample.
