I'am currently using this series on top of linux-next-0214. https://patchwork.kernel.org/patch/11248331/ > When I worked this driver, I use a internal version > based on v5.4, the dts layout is different with internal tree. I looked also at: https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8-ss-conn.dtsi?h=imx_5.4.3_2.0.0 How do I adapt the usbotg3 for linux-next? I already ported some usb related dependencies from imx8-ss-conn.dtsi. But the cdns3 core driver is stucked at probe and currently I don't understand how the cdns3-imx glue layer comes into play. > > Besides, you need a PHY driver for upstream version: > https://patchwork.kernel.org/patch/11454581/ Best Regards, Oliver
