In reply to#1375550
A new compatible string, "mediatek,mt2701-u3phy", is added.

Some register settings to avoid RX sensitivity level degradation
which may arise on mt8173 platform are separated from other
platforms.

Do you mean this PHY driver support both USB2 and USB3? Then it's not really a
USB3 PHY driver right?

Sorry for my unclear description.

It supports USB3 PHY, and each USB3 PHY in fact includes a USB2 PHY and
a SuperSpeed PHY.

Thanks a lot
