That's a phy, isn't it? So node name "phy".

More importantly, are these ports really HS-only?

Apologies for this, added it for testing purpose only, forgot to remove it.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

[PATCH 2/3] arm64: dts: qcom: qdu1000-idp: enable USB nodes

[Komal Bajaj]

Enable both USB controllers and associated hsphy and qmp phy
nodes on QDU1000 IDP. Add the usb type B port linked with the
DWC3 USB controller switched to OTG mode and tagged with
usb-role-switch.

If this board has only a USB-B connector, can it really handle USB 3.0?

Here's a USB 3.0 Type-B cable, so no problem there:

@Komal, please confirm that this is the connector you have on the IDP?

Hi Bjorn,

  Sorry for the confusion. The QDU1000 IDP has a Type-C connector. The 
type-c switch present between SoC and the connector is HD3SS3220 (from TI).

  I think Dmitry's comment was that if it is 3.0, is it Type-C ? and if 
it is Type-C, then the compatible written in the being 
"gpio-usb-b-connector" would mean that there is a Type-B connector for 
someone who looks at the DT. (Dmitry, Please correct me if I understood 
the comment wrong).

  I tried to push a series for adding a compatible to gpio conn driver 
[1] to resolve this and explained the connection specifics to Dmitry [2] 
and he suggested me to add a compatible for just the switch present on 
qdu1000 idp.

Dmitry, Krzysztof,

I was looking into the code again and it turns out there is a driver 
specific to HD3SS3220 switch [3] in linux already. I tried to check if 
it can be reused here but that driver relies on I2C communication 
between the SoC and the HD3SS3220 chip to get information on role 
switch. But in QDU1000 IDP board, there is no I2C communication present 
between SoC and the switch. Those lines have been cut off. The SoC only 
knows about VBUS/ID pins (other than DM/DP/SS Lanes) and no other I2C 
connections between the switch and the SoC. We still need to make use of 
vbus/id pins to decide which role we need to shift into. Can we still go 
ahead with using usb-conn-gpio driver by adding the compatible 
(qcom,qdu1000-hd3ss3220) and using it in DT ?

Let me know your thoughts on this.

Is Qualcomm a manufacturer of the device? It is not.
Is qdu1000 a part of the device? It is not.

So the compatible string should be "ti,hd3ss3220". Which is fine to be
used in the platform driver. Just describe the differences in the
schema.
