imx8mp integrates 2 identical dwc3 based USB3 controllers and Synopsys phys, each instance has additional wakeup logic to support low power mode, so the glue layer need a node with dwc3 core sub node.

This does not validate against your own schema: arch/arm64/boot/dts/freescale/imx8mp-evk.dt.yaml: usb@32f10108: 'assigned-clock-parents', 'assigned-clock-rates', 'assigned-clocks' do not match any of the regexes: '^dwc3@[0-9a-f]+$', 'pinctrl-[0-9]+' Please, stop adding new schema and DTS which from day one have warnings/violations. It's really a lot of effort (and commits) to clean this up later. Best regards, Krzysztof
