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.
