Subject: USB 3.0 - Synopsis DWC Host-AHB - on Linux Kernel 3.10.28

Hello,

I am using Linux kernel 3.10.28 - MIPS processor (BIG Endian)

I see that XHCI fails during xhci_device_alloc() because of
wait_for_completion_interruptible_timeout () when I connect a device.

So, I thought of initializing host controller as BE as my host is BE.
But this time, it failed much earlier, i.e in xhci_handle_event()
itself for the check le32_to_cpu(event->event_cmd.flags) & TRB_CYCLE)
!=  xhci->event_ring->cycle_state)

I would like to know if any of you used Synopsis DWC Host-AHB and got
successful device detection. Also, Please let me know if XHCI needs
special configuration on Big Endian system.

Thanks
