Why is this port disconnected? It it really N/C?

Hi Dmitry,

Sorry for the confusion, Can we do it as follows:

hub:                    Hd3ss3220   typec-connector

usb_hub_2_1 <-> port@1       port@1 <-> empty
usb_hub_3_1 <-> port@2       port@2 <-> <empty>
                              port@0 <-> port@0

You still missed the _why_. Why port@1 of HD3SS3220 is not connected?

There are no remote endpoints added in dwc3 node. Since we are making dr_mode host. Hence keeping this remore endpoint empty.

So can you like.. add the endpoints under that node and problem
solved?

quoted

solved?

The lines go from SoC to Hub directly and not the port controller. And
hence can't connect remote endpoints of dwc3 controller to the hd3
node.

A comment in the commit message (and/or in the DTSI) would be nice.

Regards,
Krishna,
