It allows drivers to avoid spurious interrupts from noisy sources so if the hardware supports it the driver can avoid having to explicitly wait for the signal to become stable and software has to cope with fewer events. We've lived without it for quite some time, though. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
