I'm fairly certain it wouldn't. Each of the interrupts on my hardware has a corresponding bit in a control register that determines if it's rising or falling-edge triggered -- thus the need for my patch. To capture both directions, it's necessary to modify the control register when a falling edge is detected, so that the corresponding rising edge can be collected afterward. May I ask why you're thinking of converting to level-triggering? Perhaps it would be better to provide an option in the platform_device structure to set edge- or level-triggering, similar to the change I'm proposing for interrupts that can only signal one way at a time. - Cory -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
