1*4882a593Smuzhiyun[PATCH] ARM: dts: imx6qdl-udoo: Disable usbh1 to avoid kernel hang
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunCurrently the kernel hangs when USB Host1 is enabled due to the lack of
4*4882a593Smuzhiyunsupport for controlling the USB hub clock and GPIO reset line.
5*4882a593Smuzhiyun
6*4882a593SmuzhiyunPeter Chen has made several attempts to fix this problem, but his series
7*4882a593Smuzhiyunhas not been applied yet, so better disable USB host1 for now to avoid
8*4882a593Smuzhiyunthe kernel hang.
