This does not validate against your own schema:
arch/arm64/boot/dts/freescale/imx8mp-evk.dt.yaml: usb at 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
