Subject: [PATCH 4/3] dt-bindings: iio: io-channel-mux: add optional #io-channel-cells
Date: Sat, 9 Oct 2021 00:11:21 +0200	[thread overview]
Message-ID: <43e22ba4-0619-49bc-8062-b561cf19ca23@axentia.se> (raw)
In-Reply-To: <1633661172.633248.1409599.nullmailer@robh.at.kernel.org>

Needed for in-kernel use of the child channels of the mux.

Fixes problems like this, reported by dtbs_check:
adc0mux: '#io-channel-cells' does not match any of the regexes: 'pinctrl-[0-9]+'
	arch/arm/boot/dts/aspeed-bmc-ampere-mtjade.dt.yaml
