[PATCH] dt-bindings: iio: afe: current-sense-shunt: add io-channel-cells
From: Krzysztof Kozlowski <hidden>
Date: 2021-05-06 15:06:47
Also in:
linux-iio, lkml
Subsystem:
iio subsystem and drivers, iio unit converter, open firmware and flattened device tree bindings, the rest · Maintainers:
Jonathan Cameron, Peter Rosin, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
The current-sense-shunt is an IIO provider thus can be referenced by IIO
consumers (via "io-channels" property in consumer device node).
Such provider is required to describe number of cells used in phandle
lookup with "io-channel-cells" property. This also fixes dtbs_check
warnings like:
arch/arm/boot/dts/s5pv210-fascinate4g.dt.yaml: current-sense-shunt:
'#io-channel-cells' does not match any of the regexes: 'pinctrl-[0-9]+'
Fixes: ce66e52b6c16 ("dt-bindings:iio:afe:current-sense-shunt: txt to yaml conversion.")
