I'am currently using this series on top of linux-next-0214.

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.
