Subsystem:
ad4030 adc driver (ad4030-24/ad4630-16/ad4630-24/ad4632-16/ad4632-24), analog devices inc iio drivers, iio subsystem and drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Michael Hennerich, Nuno Sá, Jonathan Cameron, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
In setups designed for high speed data rate capture, a PWM is used to generate the CNV signal that issues data captures from the ADC. Document the use of a PWM for AD4030 and similar devices.
