[PATCH v7 3/8] dt-bindings: iio: adc: adi,ad4030: Add PWM

From: Marcelo Schmitt <marcelo.schmitt@analog.com>
Date: 2026-02-05 16:48:21
Also in: linux-devicetree, linux-iio, lkml
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.
