The i.MX5,6,7 dtsi files use gpio-ranges as well and other i.MX dtsi files could also use it. Sascha

All other cases use maximum one element in gpio-ranges, so they are covered so I assumed they are continuous. But if it not the case, I can make all them maximum 2. Best regards, Krzysztof

Anyway, arch/arm/boot/dts/imx6dl.dtsi has this: &gpio1 { gpio-ranges = <&iomuxc 0 131 2>, <&iomuxc 2 137 8>, <&iomuxc 10 189 2>, <&iomuxc 12 194 1>, <&iomuxc 13 193 1>, <&iomuxc 14 192 1>, <&iomuxc 15 191 1>, <&iomuxc 16 185 2>, <&iomuxc 18 184 1>, <&iomuxc 19 187 1>, <&iomuxc 20 183 1>, <&iomuxc 21 188 1>, <&iomuxc 22 123 3>, <&iomuxc 25 121 1>, <&iomuxc 26 127 1>, <&iomuxc 27 126 1>, <&iomuxc 28 128 1>, <&iomuxc 29 130 1>, <&iomuxc 30 129 1>, <&iomuxc 31 122 1>; }; I don't think it makes sense to specify maxItems.

Indeed, I will skip the max limit. Best regards, Krzysztof

The GPIO controller node can have gpio-ranges property.
