Sounds like we need to do some SoC specific debug on orientation switching in the PHY.

I wonder how many lanes dp_opts->lanes says for your part ?

Also potentially not having "orientation-switch" in &usb_1_qmpphy{} but, I think we discussed that before.

So either

- PHY orientation turn-around isn't working or
- DTS orientation-switch isn't happening

for you
