cpu_is_at91xx have been removed from the kernel, using the correct
compatible should be enough, see
http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/usb/gadget/udc/at91_udc.c?id=f0bceab4e3b528e799aba8fda8d2936fcfd41f1f


Thanks for you information. Missing this patch, check the next-20150209, 
it is here. I will base on next-20150209, so this patch no need anymore, 
only need to change the dts(i) file now.


Thanks again.
