Downstream kernel also configures

> snps,tx-thr-num-pkt = /bits/ 8 <1>;

is this not needed and omitted on purpose?

I got these dtbs check warnings:

arch/arm64/boot/dts/freescale/imx95-tqma9596sa-mb-smarc-2.dtb:
 phy@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@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?

Alexander

Yes, on purpose. The later newer soc doesn't need these properties.

Are you checking on usb tree? You need below two dt-binding patch.

 - dt-bindings: usb: dwc3-imx8mp: add compatible string for imx95
 - dt-bindings: phy: imx8mq-usb: add compatible "fsl,imx95-usb-phy"

Host-only mode with Type-A connector? No Typec-C connector?
Sorry, I do not get your meaning.

Yes, these patches are already in linux-next. I'm on next-20241016.

Yes, no Type-C connector. Actually not even a Type-A as there is an
on-board USB hub attached to this host.

Understood. imx95 usb phy can work w/o typec. So I may need modify the
dt-binding to be similar to the following format:

If property "orientation-switch" exist and compatible contain "fsl,imx95-usb-phy",
then refer to usb-switch.yaml.

However, I'm not sure how to do that now. Do you know?

Thanks,

What 'works' is adding an empty port node to the usb3_phy. But this feels like a workaround.

DT guys, can you more input how to proceed?
