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
