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

From: Nicolas Ferre
Date: Thu Jun 18 2009 - 11:13:50 EST


From: Hong Xu <hong.xu@xxxxxxxxx>

Modify both host and gadget USB drivers for at91sam9g10.
This add a clock management equivalent to at91sam9261 on usb drivers.
It also add the way of handling gadget pull-ups (like the at91sam9261).
