Speaking of which ... the EDMA channels used for those GPIO banks should basically not be used as hardware triggers. But they can work just fine for software triggering, flavors of completion IRQs, chaining, etc. The same is *probably* true for the non-banked GPIO IRQs, which nobody seems to have found out yet how to use. (As in, GPIO-2 reported directly through AINTC, with level trigger options.) Not needed now ... but at some point I think the EDMA init logic might want have a way that platform code can tell it "here are some more channels you can hand out whenever hardware triggering doesn't matter". (More examples include the clocksource/clockevent and watchdog EDMA channels, and surely a few others.) _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
