Putting my initial reporter hat on, USB OHCI is completely broken in lk 3.13.0 rc1 and rc2 for AT91 family members. So it is difficult to make the situation worse. IMO the whole 4 patches should go in, since it only impacts that family. Also the kernel is more than a month away from release. Perhaps the naysayers should be looking around for whatever else the of/irq: Pass trigger type in IRQ resource flags patch has broken.
