Marek,

Do you still have IMX8MP USB host working on top of v2022.07-rc2,
master, or imx-master? It worked for me previously at some point
applying your dwc3 glue series [1] from a repo you pointed me to that
I can no longer find but now I see an issue where device_probe fails:

u-boot=> usb start
starting USB...
Bus usb at 38100000: probe failed, error -61
Bus usb at 38200000: probe failed, error -61
No working controllers found

The failure is that dwc3_glue_probe fails to find 'usb3-phy' due to
that being in the phy-names node of usb at 38100000 and not its parent
usb at 32f10100

Am I missing a patch perhaps to dwc3_glue_probe in dwc3-generic.c?
