Looking at qcom,qusb2-phy.yaml bindings and qusb2_phy_vreg_names[] in

Why not add it to the regulators list instead? It's a valid regulator for this hw.

I do not have enough information to be sure. Could you cook up a patch to
update bindings and driver, if you think that's the case? I will be
happy as long as that DTS, bindings and driver are on the same page.
