I will include this patch series in at91-l2 branch on:
git://github.com/at91linux/linux-at91.git
(mind the removal of -2.6-)
But there are several changes to ohci-at91 which also may fit in an USB
git tree...
According to the nature of changes, I think it is better to send them
upstream through the AT91 - arm-soc flow.
Thanks Thomas, best regards,
