One conflicting resource is usb, where the imx8dxl has a second usb2 phy @5b110000, while the generic imx8 dtsi has one usb2 phy and one usb3 phy, and the usb3otg @5b110000. When including both imx8dxl-ss-conn.dtsi and imx8-ss-conn.dtsi as done in imx8dxl.dtsi this leads to a duplicate unit-address warning. The usb3otg node was introduced after the initial imx8dxl support with commit a8bd7f155126 ("arm64: dts: imx8qxp: add cadence usb3 support") and since then leads to warnings like this (when built with W=3D2): DTC arch/arm64/boot/dts/freescale/imx8dxl-evk.dtb =E2=80=A6/arch/arm64/boot/dts/freescale/imx8-ss-conn.dtsi:148.24-182.4:= Warning (unique_unit_address): /bus@5b000000/usb@5b110000: duplicate unit-= address (also used in node /bus@5b000000/usbphy@5b110000) also defined at =E2=80=A6/arch/arm64/boot/dts/freescale/imx8dxl-ss-hs= io.dtsi:41.23-50.4 also defined at =E2=80=A6/arch/arm64/boot/dts/freescale/imx8dxl-evk.d= ts:645.8-653.3 Delete usb3 related nodes at dxl to fix above warning.
