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. Regards, M.
