From 31f1961d64ef50f61f489b79635f1c3ef0badad2 Mon Sep 17 00:00:00 2001 From: Kunihiko Hayashi Date: Tue, 26 Dec 2017 10:03:40 +0900 Subject: arm64: dts: uniphier: add has-transaction-translator property to usb node for LD11 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.
