It was small, but important difference. There is MUX, which selects which port to be used by USB2.0 controller. On DragonBord8074 it should be second one. This is what "qcom,phy-num" DT property supposed to select. Unfortunately this is not enough. Register 0xfd4ab000 should contain value different than zero.
