Each serial device can change the status of the gpio-pin before suspendig and register and handler on it (I think one interrupt handler for all the serial that can do that), then reset it after resume. I think not all the serial device can do that in the atmel architectures but I suppose that can be very usefull for example in gprs application. > This patch doesn't really change that assumption anyway -- it just > implements it in a way more consistent with the current serial core. > > Haavard Regards Michael __________________________________________________ Do You Yahoo!?
