[PATCH v2 1/2] dt-bindings: iio: afe: current-sense-amplifier: Add io-channel-cells

Primoz Fiser
2025-09-05T06:55:13Z

The current-sense-amplifier 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.
