 configured as host-only

Hello,

Similar issue with ZynqMP board related to that patch:

xilinx-psgtr fd400000.phy: lane 3 (type 1, protocol 3): PLL lock timeout
phy phy-fd400000.phy.3: phy poweron failed --> -110
dwc3 fe300000.usb: error -ETIMEDOUT: failed to initialize core

With CONFIG_USB_DWC3_DUAL_ROLE and dr_mode = "host";

It may not be the correct fix.
