Needlessly so. (And presumably you're aware that the driver is also used with DaVinci ...) Note also the response I sent to Felipe.

Actually, it'd be a lot easier if you just provided a clean patch in the first place. That way it won't have to get ripped out when the musb_hdrc code goes upstream. > It should not be difficult to make a generic class driver out of this > that can be used for HSET testing on HOST side(ehci/ohci). OHCI can't do HSET ... it's not high speed. ;) > I will start working on that and soon submit a patch. - Dave ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
