Subject: [PATCH 1/1] dt-bindings: iio: adc: max1238: Add #io-channel-cells property
Date: Mon, 18 Aug 2025 16:00:13 -0400 [thread overview]
Message-ID: <20250818200014.3700738-1-Frank.Li@nxp.com> (raw)
Add #io-channel-cells property because it is multi-channel ADC.
Fix below CHECK_DTBS warnings:
arch/arm/boot/dts/nxp/ls/ls1021a-iot.dtb: adc@35 (maxim,max1239): '#io-channel-cells' does not match any of the regexes: '^pinctrl-[0-9]+$'
from schema $id: http://devicetree.org/schemas/iio/adc/maxim,max1238.yaml#
