OK, right. Thank you for your guidance. Then, do you mean the following? If it is right, I will send the v2 patch. ./arch/arm/boot/dts/exynos5440.dtsi pcie@290000 { ..... status = "disabled"; }; pcie@2a0000 { ..... status = "disabled"; }; ./arch/arm/boot/dts/exynos5440-ssdk5440.dts pcie@290000 { ..... status = "okay"; }; pcie@2a0000 { ..... status = "okay"; }; Best regards, Jingoo Han -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
