+[PATCH] ARM: dts: imx6qdl-udoo: Disable usbh1 to avoid kernel hang
+
+Currently the kernel hangs when USB Host1 is enabled due to the lack of
+support for controlling the USB hub clock and GPIO reset line.
+
+Peter Chen has made several attempts to fix this problem, but his series
+has not been applied yet, so better disable USB host1 for now to avoid
+the kernel hang.
