SubjectRe: [PATCH 4/5] at91/USB: USB drivers modifications for at91sam9g10
Hi,

Here is a little "ping" about integration of this patch.

I wonder if we can consider its inclusion as at91sam9g10 is now
integrated in mainline.
Do you want me to split this in several pieces for host/gadget split.

Thanks.
