I could accept patch > for your specific platforms, like: > > + select EXTCON if !ARCH_XXXX The patch doesn't remove extcon support from chipidea driver. I just want to not select EXTCON unconditionally, but let the users choose. If the users need extcon, they could enable EXTCON themselves I just searched all the dts in arch/arm/boot/dts and arch/arm64/boot/dts only the four dts give extcon phandle to chipidea host, other users don't make use of it: arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi arch/arm/boot/dts/qcom-apq8074-dragonboard.dts arch/arm/boot/dts/qcom-msm8974-fairphone-fp2.dts arch/arm/boot/dts/qcom-msm8974-sony-xperia-castor.dts Thanks -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
