When a full/low speed device is connected to USB 2.0 port on UniPhier SoC that has ehci controller, the kernel shows the following messages. | usb usb1-port1: Cannot enable. Maybe the USB cable is bad? | usb usb1-port1: Cannot enable. Maybe the USB cable is bad? | usb usb1-port1: Cannot enable. Maybe the USB cable is bad? | usb usb1-port1: unable to enumerate USB device To fix the issue, the driver needs to enable Transaction Translator on ehci root hub. This adds 'has-transaction-translator' property to each node.
