Subject: [PATCH] arm64: dts: imx8dxl-ss-conn: Disable USB3 nodes
Date: Tue, 10 Jun 2025 08:07:56 +0200 [thread overview]
Message-ID: <20250610060756.8212-1-ada@thorsis.com> (raw)
The i.MX 8DualXLite/8SoloXLite has a different connectivity memory map
than the generic i.MX8 has. 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 building with ptxdist):
CPP generic/platform-v8a/build-target/linux-6.12/arch/arm64/boot/dts/freescale/imx8dxl-evk.dts
DTC generic/platform-v8a/packages/linux-6.12/boot/imx8dxl-evk.dtb
/home/adahl/Work/bsp/thorsis/generic/platform-v8a/build-target/linux-6.12/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)
