I got these dtbs check warnings:

arch/arm64/boot/dts/freescale/imx95-tqma9596sa-mb-smarc-2.dtb:
 phy at 4c1f0040: 'oneOf' conditional failed, one must be fixed:
        'port' is a required property
        'ports' is a required property
        from schema $id: http://devicetree.org/schemas/phy/fsl,imx8mq-usb-phy.yaml#
arch/arm64/boot/dts/freescale/imx95-tqma9596sa-mb-smarc-2.dtb: 
 phy at 4c1f0040: Unevaluated properties are not allowed ('orientation-switch' was unexpected)
        from schema $id: http://devicetree.org/schemas/phy/fsl,imx8mq-usb-phy.yaml#


How am I supposed to specify a port when the usb3 is used in host mode, thus
no USB Type-C connector and no 'port' OF-graph accordingly?

Best regards,
Alexander
