[PATCH 13/15] dt-bindings: iio: dac: adi,ad5791: Add missing bindings document
From: Jonathan Cameron <jic23@kernel.org>
Date: 2021-06-27 16:31:06
Also in:
linux-iio
Subsystem:
analog devices inc iio drivers, iio subsystem and drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Lars-Peter Clausen, Michael Hennerich, Jonathan Cameron, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
From: Jonathan Cameron <Jonathan.Cameron@huawei.com> Documenting existing bindings for this device. The Linux driver in theory 'works' without the two supplies that I have listed as required, but without a valid scale. As such I've documented it as required.
