[PATCH v5 1/5] dt-bindings: iio: hmc425a: add conditional GPIO array size constraints
From: Dumitru Ceclan <hidden>
Date: 2024-02-20 15:36:01
Also in:
linux-iio, lkml
Subsystem:
analog devices inc iio drivers, iio subsystem and drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Nuno Sá, Michael Hennerich, Jonathan Cameron, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
ADRF5740 and HMC540S have a 4 bit parallel interface.
Update ctrl-gpios description and min/maxItems values depending on the
matched compatible to correctly reflect the hardware properties.
Fixes: 79f2ff6461e7 ("dt-bindings: iio: hmc425a: add entry for ADRF5740 Attenuator")
Fixes: 20f87a9a26be ("dt-bindings: iio: hmc425a: add entry for HMC540S")
