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) =E2=80=A6/arch/arm64/boot/dts/freescale/imx8-ss-hsio.dtsi:52.23-81.4: W= arning (unique_unit_address): /bus@5f000000/pcie@5f010000: duplicate unit-a= ddress (also used in node /bus@5f000000/pcie-ep@5f010000) 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 After the change that usb related warning is gone: DTC arch/arm64/boot/dts/freescale/imx8dxl-evk.dtb =E2=80=A6/arch/arm64/boot/dts/freescale/imx8-ss-hsio.dtsi:52.23-81.4: W= arning (unique_unit_address): /bus@5f000000/pcie@5f010000: duplicate unit-a= ddress (also used in node /bus@5f000000/pcie-ep@5f010000) 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 Signed-off-by: Alexander Dahl --- Notes: v2: - reworded commit message (build on mainline with W=3D2) - rebased on v6.16-rc3 =20 v1: - Link: https://lore.kernel.org/linux-devicetree/20250610060756.8212-1-= ada@thorsis.com/ arch/arm64/boot/dts/freescale/imx8dxl-ss-conn.dtsi | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm64/boot/dts/freescale/imx8dxl-ss-conn.dtsi b/arch/arm6= 4/boot/dts/freescale/imx8dxl-ss-conn.dtsi index 9b114bed084b..a66ba6d0a8c0 100644 --- a/arch/arm64/boot/dts/freescale/imx8dxl-ss-conn.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8dxl-ss-conn.dtsi @@ -5,6 +5,8 @@ =20 /delete-node/ &enet1_lpcg; /delete-node/ &fec2; +/delete-node/ &usbotg3; +/delete-node/ &usb3_phy; =20 / { conn_enet0_root_clk: clock-conn-enet0-root { base-commit: 86731a2a651e58953fc949573895f2fa6d456841 --=20 2.39.5
