Hi,
I'm running OpenWRT Kernel 3.8.3 (which already has
f66dea709cd9309b2ee9f715697818001fb518de and
5ed338778f917a035f0f0a52327fc4f72e36f7a1 applied) on a P1020WLAN (QorlQ, PPC)
device.
Before updating the kernel from 3.3.0, USB host support was working fine. Now I
get "fsl-ehci: USB PHY clock invalid" messages in dmesg and the lsusb output is
empty, so USB host support is not working. When I apply the following patch,
USB host support starts working again, so I guess
3735ba8db8e6ea22ad3ff524328926d8d780a884 is the cause.
Do you have an idea how to fix it more appropriately?
Thanks,
M. Braun
